Waste Minimisation – Role of Public, Private and Community Sector

waste-minisationWhen it comes to waste minimisation and moving material up the waste hierarchy you will find partisan advocates for the roles of the public, private and community sectors. Each will tell you the reasons why their sector’s approach is the best. The private sector will extol their virtues as the only ones capable of efficiently and effectively doing the job.  They rightly note that they are the providers on the front lines who actually recover the vast majority of material, that the private sector approach drives innovation and efficiency, and that if waste minimisation is to be sustainable this must include economic sustainability.

The community sector on the other hand will make a strong case to say that their model, because it commonly encompasses social, environmental, and economic outcomes, is able to leverage value from recovered materials to dig deeper into the waste stream, to optimise recovered material quality, and to maximise employment and local economic benefit.

Before recycling and composting were economically viable prospects, community sector organisations led the way, developing many of the techniques now widely used. They remain the leaders in marginal areas such as furniture reuse, running projects that deliver environmental outcomes while providing wider community benefits such as rehabilitation and training for marginalised groups.

Finally, in the public sector corner, advocates will point out that the profit-driven private sector will only ever recover those materials that are able to generate positive revenues, and so cannot maximise waste minimisation, while social outcomes are strictly a secondary consideration. The community sector, on the other hand, while encompassing non-monetary values and capable of effective action on a local scale, is not set up to deliver these benefits on a larger scale and can sometimes struggle to deliver consistent, professional levels of service.

The public sector can point to government’s role in legislating to promote consistent environmental and social outcomes, while councils are major providers and commissioners of recycling services and instrumental in shaping public perceptions around waste issues. The public sector often leads in directing activity towards non-monetary but otherwise valuable outcomes, and provides the framework and funding for equity of service levels.

So who is right? Each sector has good arguments in its favour, and each has its weaknesses. Does one approach carry the day?  Should we just mix and match according to our personal taste or based on what is convenient?

Perhaps we are asking the wrong question. Maybe the issue is not “which approach is better?” but instead “how might the different models help us get to where we ultimately want to go?”

Smells Like Waste Minimisation

So where do we want to go?  What is the waste minimisation end game?

If we think about things from a zero waste perspective, the ideal is that we should move from linear processes of extraction, processing, consumption and disposal, to cyclical processes that mimic nature and that re-integrate materials into economic and natural systems.  This is the nirvana – where nothing is ‘thrown away’ because everything has a further beneficial use.  In other words what we have is not waste but resources.  Or to put it another way – everything has value.

Assuming that we continue to operate in an essentially capitalist system, value has to be translated into economic terms.  Imagine if every single thing that we now discard was worth enough money to motivate its recovery.  We would throw nothing away: why would we if there was money to be made from it?

So in a zero waste nirvana the private sector and the community sector would take care of recovery almost automatically.  There might evolve a community and private sector mix, with each occupying different niches depending on desired local outcomes. There would be no need for the public sector to intervene to promote waste minimisation.  All it would need to do would be to set some ground rules and monitor the industry to ensure a level playing field and appropriate health and safety.

Sectoral Healing

Returning to reality, we are a long way from that zero waste nirvana.  As things stand, a bunch of materials do have economic value, and are widely recycled. Another layer of materials have marginal value, and the remainder have no value in practical terms (or even a negative value in the case of hazardous wastes).

The suggested shift in perspective is most obvious in terms of how we think about the role of the public sector. To bring us closer to our goal, the public sector needs to intervene in the market to support those materials of marginal value so that they join the group that has genuine value.

Kerbside (or curbside) collection of certain materials, such as glass and lower value plastics, is an example of an activity that is in effect subsidised by public money. These subsidies enable the private sector to achieve environmental outcomes that we deem sufficiently worthwhile to fund.

However, the public sector should not just be plugging a gap in the market (as it largely does now), but be working towards largely doing itself out of a job. If we are to progress towards a cyclical economy, the role of the public sector should not be to subsidise marginal materials in perpetuity, but to progressively move them from marginal to genuinely economic, so that they no longer require support.

At the same time new materials would be progressively targeted and brought through so that the range and quantity requiring disposal constantly shrinks.  This suggests a vital role for the public sector that encompasses research, funding for development of new technologies and processes, and setting appropriate policy and price structures (such as through taxes, levies, or product stewardship programmes).

Similarly, the community sector, because it is able to ‘dig deeper’ into the waste stream, has a unique and ongoing role to play in terms of being able to more effectively address those materials of marginal value as they begin to move up the hierarchy.  The community sector’s unique value is its ability to work at the frontiers.

Meanwhile, the private sector’s resources and creativity will be needed to enable efficient systems to be developed to manage collection, processing and recycling of materials that reach the threshold of economic viability – and to create new, more sustainable products that fit more readily into a waste minimising world.

In the end, then, perhaps the answer is to stop seeing the three models as being in competition. Instead, we should consciously be utilising the unique characteristics of each so that we can evolve our practices towards a future that is more functional and capable of delivering the circular economy that must eventuate if we are to sustain ourselves on this planet.

Foam Packaging: Take the Bull by the Horns

foam-packaging-wasteNew York City and Oxford are two prominent examples of local authorities that have tried to restrict the use of foam packaging for takeaway food and drink, arguing that doing so would reduce the environmental impact of waste in a way that alternative approaches could not. In both cases, the intervention of packaging manufacturers has lifted or watered down the rules. Other administrations might well be put off the idea of similar measures – but the argument for cracking down on foam packaging that almost unavoidably gives rise to regional waste management problems, as well as wider environmental degradation through its contribution to litter, remains hard to ignore. Bans, however, may not be the only option.

Menace of Foam Packaging

A particular target for action has been expanded polystyrene (EPS). It’s rigid and a good insulator, and yet a great deal of it is air, making it very lightweight: it’s little wonder that EPS trays, cups and ‘clamshells’ are staples of the industry. It’s also widely used in pre-moulded form in the packaging of electronics, and as loose fill packaging in the form of ‘peanuts’.

While no-one would deny its convenience, for waste managers, EPS is a challenge, for many of the same reasons that it is popular. It’s light and difficult to compact, so it fills up bins and collection vehicles quickly; and takes up a great deal of space if you try to bulk and haul it for recycling.

It’s easy to see, then, why in 2013 New York City’s council voted unanimously to prohibit the use of EPS by all restaurants, food carts, and stores. Yet from the outset, the ban proposal faced stiff opposition from retailers and manufacturers, with packaging giant Dart Container Corp. and the American Chemistry Council reportedly organising a million dollars’ worth of lobbying against the legislation. Once it took effect, the industry quickly managed to overturn it in the courts last month.

Ban on the Run

The city had found that the recycling of EPS was not, in fact, environmentally effective, economically feasible and safe, and NYC was declared EPS-free in July 2015. But in a widely reported ruling, Justice Margaret Chan deemed the decision “arbitrary and capricious”: the complex case turned on the question of whether there was a recycling market for EPS, and the judge decided that Commissioner Kathryn Garcia of the city’s Department of Sanitation had failed to take account of evidence supplied by the industry that such a market did exist.

Although it lacked the courtroom drama of the New York City case, a similar story played out in Oxford last year. The city council proposed to use its licensing powers to require street traders to use only “biodegradable and recyclable” packaging and utensils. The move was stymied by semantics: the Foodservice Packaging Association lobbied for the phrasing of the proposed licensing rule to be amended to ‘biodegradable or recyclable’. That tiny change allowed continued use of expanded polystyrene, as it is technically recyclable (though certainly not biodegradable).

Oxford’s traders are also required to arrange for the correct disposal of EPS takeaway packaging from their premises. This is an odd requirement given that take-away food is usually – well – taken away, and then disposed of in street bins, household bins, or in no bin at all. Unfortunately, Oxford City Council – like almost every other council in the country – isn’t currently able to send EPS for recycling, so the EPS it collects will in practice end up in the residual stream. The EPS litter that escapes will linger in the environment for centuries to come.

Foam Suit

It seems that both courts and councillors have been impressed by the manufacturers’ argument: ‘Why ban a highly efficient product when you can invest in recycling it instead?’ However, there are three important points that count against this contention.

The first is that, whilst EPS can technically be recycled, the economics of doing so remain tenuous. Zero Waste Scotland’s report on Plastic Recycling Business Opportunities found that polystyrene waste compacting and collection was the only one of five options considered that did not represent a viable business opportunity in Scotland.

In order to make the finances of collecting EPS for recycling stack up in New York, Dart Corporation and Plastics Recycling Inc. had to offer to provide the city with $500,000 of sorting technology; pay for four staff; and guarantee to buy the material at $160 per tonne for five years. Without this (time limited) largesse, New York’s ban would likely have stood.

They also provided a list of 21 buyers, who they claimed would purchase dirty EPS – although when the city did a market test, it could find no realistic market for the material. It’s hard to know whose view of the US market is correct; however, in the UK, the market is definitely weak.

Of the 34 EPS recyclers listed by the BPF Expanded Polystyrene Group, 12 only accept clean EPS – ruling out post-consumer fast food waste. Another dozen will only accept compacted EPS, creating an extra processing cost for anyone attempting to separate EPS for recycling. That leaves a maximum of ten UK outlets: not enough to handle the potential supply, and leaving large tracts of the country out of economic haulage range for such a bulky, lightweight material.

Foam fatale

The second is that it’s difficult to get a high percentage of takeaway food containers into the recycling stream. Food eaten on the go is likely, at best, to go into a litter bin. And if it’s littered, because it’s light, EPS can also easily be blown around the streets, contributing to urban, riverine and ultimately marine litter. It’s also very slow to break down in the natural environment. Polystyrene has been found to make up 8% of marine litter washed up on North East Atlantic beaches; in all, plastics account for three quarters of this litter. The cost, particularly for coastal and island nations, is only beginning to be recognised.

That leads on to the third argument: while EPS undoubtedly works, less damaging alternatives are clearly available. Vegware, for example, allows takeaway boxes to be moved up the waste hierarchy – from disposal to composting. Reducing impacts was clearly a consideration in Oxford: in the words of Councillor Colin Cooke:

“It is about making the waste that we do have to get rid of more user-friendly and sustainable.”

The economic and technical difficulty in recycling EPS, combined with the long-term impacts of its littering and disposal, led Michelle Rose Rubio to conclude, in an Isonomia article last year, that environmentally minded people – and perhaps governments – should perhaps avoid it altogether.

Silver Lining

Despite the discouraging events in New York and Oxford, there’s better news from elsewhere. Bans remain in place in Toronto and Paris (both dating from 2007), while Muntinlupa in the Philippines, and the coastal state of Malaka in Malaysia have imposed charges, fines, and biodegradable replacements for EPS food packaging, eventually leading to bans.

Scottish Environment Secretary Richard Lochhead has indicated that the Scottish Government is: “considering a number of options in line with the commitment in the national litter strategy to influence product design of frequently littered items to reduce their environmental impact… [W]e note a number of US cities have introduced bans on Styrofoam products, most recently New York City. We are keen to learn from these cities’ experience of introducing and implementing such bans.”

In Wales, a polystyrene ban petition lodged last year by Friends of Barry Beaches has been picking up support. The Foodservice Packaging Association’s pre-emptive opposition to the notion certainly suggests we haven’t heard the last of EPS food packaging bans in the UK.

However, bans are not the only way to deter the use of problem products. England has just joined the ranks of countries to impose a charge for single use plastic bags. Belgium has a tax on disposable cutlery, and Malta taxes numerous products on environmental grounds, including chewing gum and EPS clamshells. Whilst beyond the powers of local authorities, fiscal measures could drive change while being a bit less of a blunt instrument than a ban.

While EPS manufacturers may have scored some recent successes, they haven’t won the overarching argument. As we push towards a more circular economy, the pressure to reduce our reliance on materials that are inherently hard to recycle, which tend to escape into the environment, and which don’t decompose naturally, will grow. For EPS fast food packaging, the chips could soon be well and truly down.

11 Ideas for Easier Recycling at Home

Going green isn’t just meant for Earth Day. Going green is a way of life. However, Earth Day is a day we pause and commemorate, acknowledge and support environmental programs and Earth-saving strategies. It is also a great day to commit or recommit to employ earth-friendly practices in your life, at home and in the office. There are countless things you can do to “go green.” Most of these things are ease to incorporate into your life. Recycling is one of the easiest ways to go green. Recycling is the process of obtaining or retaining waste and converting it into usable, new materials. Some things that can be used to recycle are:

Recycling is actually a great way to conserve raw resources into energy. Recycling at least one ton of paper can save 7,000 gallons of water and 17 trees, according to the Environmental Protection Agency.

As you see, recycling is an effective and simple way to help the environment. It is something the entire family can do too. Before recycling, call your local waste management services. Determine how to you need to sort and pack items for recycling. In addition, you want to know what day or days the waste management services collects recycling. Check with them to find out where you safely dispose of light bulbs, hazardous materials and batteries. These cannot be recycled or put in the trash.

Your local waste management service has different rules about how items must be sorted, cleaned and packaged. Metal, cardboard, plastics, aluminum, glass and paper can be recycled.

It can be tricky to recycle plastics because some can break down easier than other plastics. The number located on the plastic item will determine if it can be recycled. It will also determine if the plastic can be picked up for recycling.

Although plastics are trickier to sort and recycle, it’s important to dispose of them properly. One important factor to establishing a recycling a program at work, school or home is to create a system that works for everyone. Here are a few favorites we like:

Recycling is about convenience, convenience and more convenience! When incorporating a successful recycling program, make bins easily accessible. They should be in an area that is easily visible and used like the utility room or kitchen where they can be seen and used.

Now, if you need a simple recycling system everyone can follow (even kids), use caster and baskets. These are easy to access and use. They slide out of site when not in use.

You may not have time to personally decorate trash cans by spray painting them. How about using printable labels. These labels can go generic bins to help separate recyclables.

Batteries are not to be recycled. They cannot be put into a trash can for non-recycling either. Instead, they should be properly thrown away at a collection center or a participating auto part store. The same thing should be done with light bulbs.

Make a special area of your home or office to use as a personal sorting center. This is where you can sort and clean recyclables. You may want to look at some personal recycling centers to get an understand of what you need.

Many people do not have an area they can keep bulky recycling or trash in the home or office. If this is the case for you, create a dedicated spot in the garage or other area. It won’t take long before your family or co-workers are pitching in to recycle.

Recycling is full of great ideas to help the environment. Find the ones you like. Used them in your successful recycling program.

Recycling of Polyvinyl Chloride

Polyvinyl chloride is one of the most widely used plastics worldwide. A major problem in the recycling of polyvinyl chloride is the high chlorine content in raw PVC and high levels of hazardous additives added to the polymer to achieve the desired material quality. As a result, PVC requires separation from other plastics before mechanical recycling. PVC products have an average lifetime of 30 years, with some reaching 50 or more years.  This means that more PVC products are reaching the end-of-life and entering the waste stream, and the amount is likely to increase significantly in the near future.

PVC Recycling Methods

Currently, PVC is being recycled by either one of the two ways:

  • Mechanical recycling – This involves mechanically treating the waste (e.g. grinding) to reduce it into smaller particles.  The resulting granules, called recyclate, can be melted and remolded into different products, usually the same product from which it came.
  • Feedstock recycling – Chemical processes such as pyrolysis, hydrolysis and heating are used to convert the waste into its chemical components.  The resulting products – sodium chloride, calcium chloride, hydrocarbon products and heavy metals to name a few – are used to produce new PVC, as feed for other manufacturing processes or as fuel for energy recovery.

In mechanical recycling, because no chemical reaction is involved, the recyclate retains its original composition. This poses a recycling challenge because PVC products, depending on their application, contain different additives.  For example, rigid PVC is unplasticized whereas flexible PVC is added plasticizers because this additive increases the plastic’s fluidity and thus, its flexibility. Even products used for the same application may still differ in composition if they have different manufacturers.

When different kinds of PVC waste are fed to a mechanical recycler, the resulting product’s composition is difficult to predict, which is problematic because most PVC products, even recycled ones, require a specific PVC content.  In order to produce a high-quality recylate, the feed ideally should not be mixed with other kinds of plastic and should have a uniform material composition.Material recycling is therefore more applicable for post-industrial waste than for post-consumer waste.

Feedstock recycling is seen to be complementary to conventional mechanical recycling as it is able to treat mixed or unsorted PVC waste and recover valuable materials.  However, a study showed that feedstock recycling (or at least the two that was considered) incurred higher costs than landfilling, primarily due to the low value of the recovered products. This provides little incentive for recyclers to pursue PVC recycling.  This may change in the future as more stringent regulations to protect the environment are enacted.  Some countries in Europe have already banned PVCs from landfills and PlasticsEurope is targeting a “zero plastic to landfill” in Europe by 2020.

Post-industrial waste is relatively pure and comes from PVC production and installation, such as cut-offs from laying of cables or scraps from the installation of window frames.  These are easily recycled since they can be collected directly from processors or installers or even recycled by producers themselves as raw material to manufacture the same product.

Post-consumer waste contains mixed material and has been used for different applications.  These are products that have reached the end-of-life or are replaced due to damage, like pipes from underground, window frames being replaced for renovation and electric cables recovered from demolition. These would require further sorting and cleaning, adding cost to the recycling process.  The recyclate produced is usually of lower quality and consequently of decreased economic value.

Recent Developments

Europe is leading the way for a more sustainable use of PVC with programs, such as RecoVinyl and VinylPlus, where recycling is advanced as one of the ways to use resources more efficiently and to divert as much waste as possible from landfills. Recovinyl, created in 2003, is an initiative of the European PVC industry to advance the sustainable development of the PVC industry by improving production processes, minimise emissions, develop recycling technology and boost the collection and recycling of waste.

Having been successful in all of its goals, including an increase in recycling of PVC across Europe to over 240,000 tonnes a year, in 2011 the PVC industry redefined the role of Recovinyl as part of the ambitious new ten-year VinylPlus sustainable development programme. VinylPlus works in partnership with consumers, businesses, municipalities, waste management companies, recyclers and converter, as well as the European Commission and national and local governments. The goal is to certify those companies who recycle PVC waste and those accredited converting companies who purchase recyclate to manufacture new products and applications.

Even if some types of PVC recycling are not feasible or economically viable at present, it will likely be reversed in the future as governments, manufacturers, consumers and other stakeholders create programs that innovate and find ways to achieve a sustainable future for the PVC industry.

Composting in Qatar

compost-qatarQatar has one of the highest per capita waste generation rates worldwide. In 2012, Qatar generated 8,000 tons of solid waste daily (excluding construction and demolition waste which amounts to 20,000 tons additional waste per day).  This number is predicted to reach 19,000 tons/day in 2032, with an annual growth rate of roughly 4.2%.

Most of these wastes end up in landfills – in 2012, more than 90% of Qatar’s solid waste were sent to landfills although the government is intensifying its efforts to reduce this amount. This percentage is extremely high compared to many industrialized countries in Europe and Asia (e.g. Austria, Denmark, Netherlands and Japan) where less than 10% of solid waste are disposed of in landfills.  These countries have high recycling rates, have invested in technologies that convert waste into energy, and apply composting process to their organic waste, especially food wastes. In some of these nations, as much as 40% of their wastes are composted.

Composting in Qatar

Currently, composting in Qatar is mainly done at the Domestic Solid Waste Management Centre (DSWMC) in Mesaieed, which houses the largest composting facility in the country and one of the largest in the world.  The waste that enters the plant initially goes through anaerobic digestion, which produces biogas that can power the facility’s gas engine and generators, followed by aerobic treatment which yields the final product.

Two types of compost are generated: Grade A (compost that comes from green waste, such as yard/park trimmings, leftovers from kitchen or catering services, and wastes from markets) and Grade B (compost produced from MSW).  The plant started its operation in 2011 and when run at full capacity is able to process 750 tons of waste and produce 52 tons of Grade A compost, 377 tons of Grade B compost, liquid fertilizer which is composed of 51 tons of Grade A compost and 204 tons of Grade B compost, and 129 tons of biogas.

This is a significant and commendable development in Qatar’s implementation of its solid waste management plan, which is to reduce, reuse, recycle and recover from waste, and to avoid disposing in landfills as much as possible.  However, the large influx of workers to Qatar in the coming years as the country prepares to host the World Cup in 2022 is expected to substantially increase solid waste generation and apart from its investments in facilities like the composting plant and in DSWMC in general, the government may have to tap into the efforts of organizations and communities to implement its waste management strategy.

Future Outlook

Thankfully, several organizations recognize the importance of composting in waste management and are raising awareness on its benefits.  Qatar Green Building Council (QGBC) has been actively promoting composting through its Solid Waste Interest Group.  Last year, they were one of the implementers of the Baytna project, the first Passivhaus experiment in the country.

This project entails the construction of an energy-efficient villa and a comparative study will be performed as to how the carbon footprint of this structure would compare to a conventional villa.  The occupants of the Passivhaus villa will also be made to implement a sustainable waste management system which includes composting of food waste and garden waste, which is meant to lower greenhouse gas emissions compared to landfilling.

Qatar Foundation is also currently developing an integrated waste management system for the entire Education City and the Food Services group is pushing for composting to be included as a method to treat food and other organic waste.  And many may not know this but composting can be and has been done by individuals in their own backyard and can even be done indoors with the right equipment.

Katrin Scholz-Barth, previous president of SustainableQatar, a volunteer-based organization that fosters sustainable culture through awareness, skills and knowledge, is an advocate of composting and has some great resources on how to start and maintain your own composting bin as she has been doing it herself.  A simple internet search will also reveal that producing compost at home is a relatively simple process that can be achieved with minimal tools.  At present, very few families in Qatar are producing their own compost and Scholz-Barth believes there is much room for improvement.

As part of its solid waste management plan as stated in the National Development Strategy for 2011-2016, Qatar aims to maintain domestic waste generation at 1.6 kg per capita per day.  This will probably involve encouraging greater recycling and reuse efforts and the reduction of waste from its source.  It would also be worthwhile to include programs that will promote and boost composting efforts among institutions, organizations and individuals, encouraging them with the fact that apart from its capability of significant waste diversion from landfills, composting can also be an attractive source of income.

Electrical Waste Collection Strategies in the UK

When disposing of small electrical items from the home, most householders only have the option of visiting their local recycling facility to drop them off. However, in order to meet recycling targets, local authorities in the UK are now considering kerbside (or curbside) collections of small domestic appliances.  This is expected to help prevent small electrical items being placed into the general waste/refuse containers from households.

This waste stream has become a priority as figures show that the average amount of WEEE (waste electrical and electronic equipment) recycled per person is only 1.3kg. The original WEEE directive targeted 4kg per person, as a recycling rate, so there is a considerable shortfall. It is important that householders find it easy to recycle their items in order to increase the rates.

Initial trials have taken place to assess the viability of these kerbside collections and the following conclusions were made:

  • On collections, small electrical items were often damaged, so the reuse of items was less likely.
  • Levels of recycling were encouraging at 140 grams per household.
  • The monetary value of the separated materials of the small items showed that a positive net value could be achieved.

Whilst the potential reuse of small electrical items was reduced it was a positive that local authorities could generate revenues from the collections. Quarterly or bi-annual collection frequencies would ensure volumes of equipment on the collections were maximised. Due to the success of the trials, the UK is likely to see more and more local authorities adopt some form of collection schedule for small electrical waste items.

An old refrigerator uses almost four times the electricity of a new one

Larger electrical items such as washing machines and fridge freezers pose a different collection issue. Some local authorities offer a collection service for bulky electrical items, however due to their size, weight and manpower requirements there is often a charge. As with smaller electrical items, you can deliver these to the local recycling facility, but you may not be able to fit these into your own vehicle. It is best to check with the local recycling facility on the options available and possibly even if they allow large, commercial sized vehicles onto site.

The collection of small electrical items from householders will ultimately increase the amount of electrical waste being recycled in the UK. It will also further promote the recycling of such items instead of placing them into general waste containers. Going forward it is hoped that more local authorities will adopt a collection schedule even if only bi-annually from their local householders.

5 Ethical, Sustainable & Eco-friendly Cost-Saving Tips

Consumers are no longer solely interested in catching a great deal. In fact, it’s the quick and cheap, disposable living mindset that has put the world in such a precarious state. Studies have shown that a business’s impact on the world plays a key role in their purchasing decision. Here are five ethical, sustainable, and eco-friendly cost-saving tips to help you cut back on your spending, and your carbon footprint.

Green SMEs

Evaluate your Utility Providers

Take a look at your utility providers to see what they’re doing to make a positive impact on the world around them. Many energy service providers offer special rates and rebates for lower consumption. Using Energybot, you can contrast and compare providers in your area. You can visit their website to find the most affordable, eco-friendly option for you.

In areas where providers are limited, you can still look at their environmental initiatives and programs that will save you money while making a positive impact. Many utility providers conduct energy audits or provide rebates for swapping out appliances and faucets for eco-friendly versions.

Hit the Thrift Shop

Online shopping makes it easy to get anything you could dream of at an affordable rate. However, there’s a good chance that someone like you had a similar item and discarded it.

Hitting the thrift shop before shopping online will not only save you money but will also have a positive environmental impact. The clothes you buy online are manufactured and shipped from all over the world. This creates carbon emissions that have a detrimental effect. There’s a hidden cost to affordable online shopping; buy local whenever possible.

Eat Seasonally

Eating food from local sources is better for the environment and the economy. By ensuring that your money stays in the local economy, you’re stimulating growth that will ultimately benefit you over time. Furthermore, you aren’t paying to have food manufactured, shipped, and stored from thousands of miles away.

Eating seasonal produce will help you save money on fresh food and improve the diversity of your diet. By consuming seasonal, local produce, you’re saving money, boosting the local economy, positively impacting the environment, and improving your health. It’s a win for all involved.

Be Water Savvy

Minimizing your water consumption will help keep your budget low and the environment thriving. Start by monitoring your consumption at home and making small changes. Shut the water off while brushing your teeth. Don’t rinse your dishes before putting them in the washer. Wait until you have a full load to do laundry.

To take it to the next level, swap your faucet and showerheads out with aerators and low-flow alternatives. Start collecting and reusing rainwater for gardening. Replace your hot water tank with a “tankless” alternative. Look at your meter usage and set reduction goals.

Reduce, Reuse, Recycle

Recycling is a great initiative that can make an incredible difference in the environment when done correctly. However, recycling is just one of the “Three R’s” to remember.

Circular-Economy

 

Reduce and reuse often go hand-in-hand. Reduce your packaging consumption by buying food in bulk and using reusable grocery bags. Before you recycle something, think about ways to give it new life. Mason jars can be used to store dry goods and pack lunches rather than using plastic containers. Keep a few large jugs handy to fill with water, rather than adding to the single-use bottle problem.

There are plenty of ways to lower your spending while taking care of the environment. Use a budgeting app like Mint to gain awareness about where your money is going. Then, use a carbon footprint calculator to evaluate your consumption. By making some simple changes to your lifestyle, you can limit harmful spending.

Municipal Waste Management in Poland

Municipal waste management in Poland has changed dramatically since the early ’90s when, as part of Poland’s privatisation program, municipal authorities were freed of their waste management obligations. The combined Polish recycling rate for dry recyclables and organic waste has increased from 5% in 2004 to 21% in 2010, according to a Copenhagen Resource Institute (CRI) study Municipal Waste Management in Poland (2013). Another source provides similar, corroborating statistics, putting the dry recycling rate in Poland at 14% and the composting rate at 7%.

The latest Eurostat data (for 2011) shows that the upward trend continuing, with the total recycled and composted reaching 28%. That is rapid rate of improvement, but leaves Poland well below the latest EU-27 average of 40% (25% recycled and 15% composted) – so what prospect is there of Poland reaching the EU’s mandatory 50% target by 2020?

Responsibility for waste disposal shifted to householders, who were left to individually contract any waste collection company of their choice. In the hard economic climate a ‘cheaper-the-better’ mentality prevailed, which did little to encourage sustainable practices. There wasn’t even an obligation on householders even to sign up for waste collection.

Landfilling was – and remains – the most common way of handling waste, but accompanying reporting and tracking methods were inadequate. Statistically, quantities of waste produced were usually larger than those collected, with the missing tonnages usually being dumped in forests or burned in domestic boilers to avoid waste disposal costs. As a result, waste management became largely uncontrolled, with a 2011 report concluding that ‘’waste management is one of the most badly neglected and at the same time one of the most urgent environmental issues for Poland.’’

Waste Management Legislation

Even after joining the EU in 2005, Poland didn’t rush to introduce reforms to improve practices and help to meet recycling targets. Only recently has Poland introduced several pieces of new waste related legislation, including:

  • Act on maintaining cleanliness and order in municipalities (2012);
  • Act on Waste (2012); and
  • Act on management of packaging and packaging waste (2013).

The first of these was revolutionary in that it gave responsibility for municipal waste collection and disposal back to municipalities. Now they are required to organise garbage collection and the separate collection of biodegradable waste and recyclable materials such as paper, metal, glass and plastic. It is expected that the new law will improve waste management control measures on a local level and greatly reduce the illegal dumping and trash burning.

The Act on Waste helps tackle the previous ‘free for all’ amongst collectors – it obliges waste handlers to act in a manner consistent with waste management principles and plans adopted at national level (by the Council of Ministers), regional level (Voivodeship) and local level (Municipality).

Poland has also this year adopted a new National Waste Management Plan, which states that an essential step towards improving the recycling rate in Poland is to increase landfill fees for recyclable, compostable or recoverable material. If acted upon, this could greatly increase the incentive to divert important municipal waste streams from landfill. The Polish market is clearly responsive to cost: in 2008 after landfill tax was significantly raised, there was a substantial reduction in waste being landfilled.

Declaration of bin-dependence

Although Polish citizens have always had to pay directly for waste collection, the new legislation has made some substantial changes to the payment system. There are now three different calculation methods. Each household is subject to a standard fee, which is then adjusted to reflect either:

  • The number of people living in a household;
  • The number of square metres covered by the property; or
  • The number of cubic metres of water used by the household per month.

The first of these options seems to be the most reasonable and has proven the most popular.

Municipalities are left to determine the standard collection fee, which as a result varies from region to region. Some municipalities charge at little as 3 Polish Zloty (around £0.56) per household, per person, per month, while some charge 20 Zloty (around £3.75).

The standard charge is also affected by a declaration made by the householder regarding waste segregation. If a property owner declares that they have separated out recyclable materials then they pay considerably lower fees. In some municipalities, this could be as low as 50% of the usual charge. Only those who declare that they don’t want to recycle pay full price. It’s rare that people do so: who would pick the most expensive option?

The problem is that some householders declare that they recycle their waste while in reality they don’t. Unfortunately, abusing the system is easy to get away with, especially since the new scheme is still in its early stages and is not yet stable. Monitoring recycling participation in order to crack down on such abuses of the system represents quite a challenging task.

Future Perspectives

Transformation periods are always hard and it is common that they bring misunderstanding and chaos. It isn’t surprising that there are problems with the new system which require ironing out, and the new legislation is nevertheless welcome. However, there is still much work to be done to provide sufficient and sustainable waste management in Poland. This will include such measures as educating the population, improving waste separation at source and securing waste treatment capacity.

Perhaps most importantly, Poland needs to take immediate action to develop its municipal waste treatment capacity across the board. If the 2020 recycling target is to be met, the country will require material recovery facilities, anaerobic digestion and in vessel composting sites, and household waste and recycling centres; and if more waste is to be diverted from landfill it will also need energy from waste (EfW) incinerators and mechanical biological treatment facilities.

According to Eurostat, only 1% of waste in Poland was incinerated in 2011. It has been confirmed so far that an EfW plant will be developed in each of Poland’s 11 biggest cities. Fortunately for Poland, the development of waste treatment installations is quite generously funded by the EU, which covers up to 80% of the total cost: EU subsidy agreements have already been signed for three of the planned EfW plants. The remaining cost will be covered by central, regional and local government.

The CRI paper presents three different scenarios for the future recycling rate in Poland. One of them is very optimistic and predicts that Poland has a chance to meet the 2020 recycling requirements, but each is based simply on a regression analysis of recent trends, rather than an analysis of the likely impact of recent and planned policy measures. What it does make clear, though, is that if Poland continues to progress as it has since 2006, it will reach the 2020 target. How many EU countries can claim that?

Recycling of EPS Foam Packaging

Municipalities and organisations are facing a growing problem in disposal and recycling of EPS foam packaging and products. EPS foam (Encapsulated Poly-Styrene) packaging is a highly popular plastic packaging material which finds wide application in packaging of food items, electronic goods, electrical appliances, furniture etc due to its excellent insulating and protective properties. EPS foam (also known as polystyrene) is also used to make useful products such as disposable cups, trays, cutlery, cartons, cases etc. However, being large and bulky, polystyrene take up significant space in rubbish bins which means that bins becomes full more quickly and therefore needs to be emptied more often.

Polystyrene is lightweight compared to its volume so it occupies lots of precious landfill space and can be blown around and cause a nuisance in the surrounding areas. Although some companies have a recycling policy, most of the polystyrene still find its way into landfill sites around the world.

Environmental Hazards of EPS Foam

While it is estimated that EPS foam products accounts for less than 1% of the total weight of landfill materials, the fraction of landfill space it takes up is much higher considering that it is very lightweight.  Furthermore, it is essentially non-biodegradable, taking hundreds perhaps thousands of years to decompose.

Even when already disposed of in landfills, polystyrene can easily be carried by the wind and litter the streets or end up polluting water bodies. When EPS foam breaks apart, the small polystyrene components can be eaten by marine organisms which can cause choking or intestinal blockage.

Polystyrene can also be consumed by fishes once it breaks down in the ocean.  Marine animals higher up the food chain could eat the fishes that have consumed EPS, thus concentrating the contaminant.  It could be a potential health hazard for us humans who are on top of the food chain considering that styrene, the plastic monomer used in manufacturing EPS has been classified by the US National Institutes of Health (NIH) and the International Agency for Research on Cancer (IARC) as a possible human carcinogen.

Styrene is derived from either petroleum or natural gas, both of which are non-renewable and are rapidly being depleted, creating environmental sustainability problems for EPS.

Trends in EPS Foam Recycling

Although the Alliance of Foam Packaging Recyclers have reported that the recycling rate for post-consumer and post-commercial EPS in the United States have risen to 28% in 2010 from around 20% in 2008, this value is still lower than most solid wastes.  According to USEPA, auto batteries, steel cans and glass containers have recycle rates of 96.2%, 70.6% and 34.2% respectively.

Because it is bulky, EPS foam takes up storage space and costs more to transport and yet yields only a small amount of polystyrene for re-use or remolding (infact, polystyrene accounts for only 2% of the volume of uncompacted EPS foams). This provides little incentive for recyclers to consider EPS recycling.

Products that have been used to hold or store food should be thoroughly cleaned for hygienic reasons, thus compounding the costs.  For the same reasons, these products cannot be recycled to produce the same food containers but rather are used for non-food plastic products.  The manufacture of food containers, therefore, always requires new polystyrene.  At present, it is more economical to produce new EPS foam products than to recycle it, and manufacturers would rather have the higher quality of fresh polystyrene over the recycled one.

The cost of transporting bulky polystyrene waste discourages recyclers from recycling it.  Organizations that receive a large amount of EPS foam (especially in packaging) can invest in a compactor that will reduce the volume of the products. Recyclers will pay more for the compacted product so the investment can be recovered relatively easier.

There are also breakthroughs in studies concerning EPS recycling although most of these are still in the research or pilot stage.  Several studies have found that the bacteria Pseudomonas putida is able to convert polystyrene to a more biodegradable plastic.  The process of polystyrene depolymerization – converting polystyrene back to its styrene monomer – is also gaining ground.
