The UK’s E-Waste Problem

There’s no doubt that the UK is in the midst of an electronic waste crisis with more than two thirds of households sitting on old phone chargers, along with other items. A study by OKdo shows exactly how big our e-waste problem is, why it’s an issue and how we can dispose of electronic items safely and responsibly.

Here we’ll take a look at the key findings and help you get clued up on what to do with your old electronic items without adding to the UK’s landfill.

The UK produces some of the biggest e-waste

With an average of 23.9kg of e-waste per person, the UK is one of the top e-waste producers in the world. Shockingly, during the first six months of 2021, the country produced an amount of electronic waste equivalent to 15 Eiffel Towers.

Cables seem to be a huge contributing factor with 140 million being stored in homes up and down the country. Not only this, households have up to 60 items of old electronics that are left unused in drawers and cupboards.

Why is there such a big e-waste problem?

The main issue appears to be that people simply don’t know how to recycle their old technology with 38% of people aged 45-54 having never done it and are unsure how to. The younger Millennials are more clued up with 31% knowing how to recycle their e-waste.

With electronic products increasing every year and the demand for more digital technology due to remote working, the problem of electronic waste is only going to get worse. Add to this our culture’s obsession with having the latest gadgets and brand-new phones and smart devices, and it’s not difficult to see we’re heading for a serious landfill and environmental issue.

How can we dispose of e-waste safely?

Donating to charity is one way to dispose of unused tech without clogging up landfill. Charities will often donate such technology to communities where items are needed so you’ll be helping others too.

There are also many company initiatives and services which encourage the recycling of old items, often rewarding you for doing so in the form of vouchers or money off a new tech device.

Council collections or recycling centres are another option if you’re looking for a local site to take your old items to. It’s worth checking your local council to make sure your device can be recycled.

By raising awareness of the e-waste problem and making sure we know how to recycle our old technology, we can contribute to a safer and greener environment and possibly help other communities along the way.

Global Trends in the Biomass Sector

There has been a flurry of activity in the biomass energy sector in recent year, with many new projects and initiatives being given the green light across the globe. This movement has been on both a regional and local level; thanks to the increased efficiency of biomass energy generators and a slight lowering in implementation costs, more businesses and even some homeowners are converting waste-to-energy systems or by installing biomass energy units.

biomass-power-trends

Latest from the United Kingdom

Our first notable example of this comes from Cornwall in the UK. As of this week, a small hotel has entirely replaced its previous oil-based heating system with biomass boilers. Fuelled from wood wastes brought in from a neighboring forest, the BudockVean hotel has so far been successful in keeping the entire establishment warm on two small boilers despite it being the height of British winter – and when warmer weather arrives, plans to install solar panels on the building’s roof is to follow.

Similar projects have been undertaken across small businesses in Britain, including the south-coast city of Plymouth that has just been announced to house a 10MW biomass power plant (alongside a 20MW plant already in construction). These developments arein part thanks to the UK government’s Renewable Heat Incentive which was launched back in 2011. The scheme only provides funding to non-domestic properties currently, but a domestic scheme is in the works this year to help homeowners also move away from fossil fuels.

Initiatives (and Setbacks) in the US

Back across the pond, and the state of New York is also launching a similar scheme. The short-term plan is to increase public education on low-emission heating and persuade a number of large business to make the switch; in the longer term, $800m will be used to install advanced biomass systems in large, state-owned buildings.

A further $40m will be used as part of a competition to help create a series of standalone energy grids in small towns and rural areas, which is a scheme that could hopefully see adopted beyond New York if all goes well.


Unfortunately, the move away from fossil fuels hasn’t been totally plain sailing across the US. Georgia suffered a blow this week as plans to convert a 155MW coal plant to biomass have been abandoned, citing large overheads and low projected returns. The company behind the project have met similar difficulties at other sites, but as of this week are moving ahead with further plans to convert over 2000MW of oil and coal energy generation in the coming years.

Elsewhere in the US, a company has conducted a similar study as to whether biomass plant building will be feasible in both Florida and Louisiana. Surveying has only just been completed, but if things go better than the recent developments in Georgia, the plants will go a long way to converting biomass to fertilizer for widespread use in agriculture in both states.

Far East Leading the Way

One country that is performing particularly well in biomass energy investment market is Japan. Biomass is being increasingly used in power plants in Japan as a source of fuel, particularly after the tragic accident at Fukushima nuclear power plant in 2011.  Palm kernel shell (PKS) has emerged as a favorite choice of biomass-based power plants in the country. Most of these biomass power plants use PKS as their energy source, and only a few operate with wood pellets. Interestingly, most of the biomass power plants in Japan have been built after 2015..

On the contrary, the US and Europe saw a fairly big fall in financing during this period; it should be noted, however, that this relates to the green energy investment market as a whole as opposed to biomass-specific funding. The increase seen in Japan has been attributed to an uptake in solar paneling, and if we look specifically to things such as the global demand for biomass pellets, we see that the most recent figures paint the overall market in a much more favorable light for the rest of the world.

Brighter Times Ahead

All in all, it’s an exciting time for the biomass industry despite the set backs which are being experienced in some regions.  On the whole, legislators and businesses are working remarkably well together in order to pave the way forward – being a fairly new market (from a commercially viable sense at least), it has taken a little while to get the ball rolling, but expect to see it blossom quickly now that the idea of biomass is starting to take hold.

Renewable Energy Stocks to Buy in the UK

The UK has become a leading voice in the fight against climate change. It’s cleantech and green energy sector consists of a startups and scaleups, all serving as a microcosm for the rest of the planet. Electric cars, renewable power and even insect-based protein for pets – this is the extent of innovation happening in the UK. Of course the UK isn’t the only country serving as an incubator for renewable energy companies – many other countries and companies are doing their part. However, if you’ve got an interest in renewable energy stocks to buy in the UK, then keep reading to know the best renewable energy companies to invest in the United Kingdom.

1. Recycling Technologies

A product of the University of Warwick conceived back in 2012, Recycling Technologies has aspirations towards a circular economy specifically for combating the effects of plastic. Thus far this green energy company has created modular technology that converts mixed plastic waste into a viable fuel for new plastic production, thus lessening the amount of new plastic on the planet.

recycling technologies

To date, Recycling Technologies has raised enough investment capital (£33.7m) to start building and commercialising its technology.

2. First Light Fusion

Conceived at the University of Oxford in 2011, First Light Fusion is looking at new was to utilise the power of inertial confinement fusion (ICF), a form of laser-focused fuel compression,  for the purposes of power generation. One of the major benefits of fusion is that unlike other forms of renewable energy like wind or solar, fusion can deliver energy in spite of weather conditions.

Thus far, First Light Fusion has secured £53m in equity funding and plans on upgrading its resources, hiring more staff and expediting its workflow. Anyone with an interest in energy and solar company stocks would do well to keep an eye on this one as it looks set to go places.

3. Propelair

Likely taking a page out of Bill Gates’ book, Propelair has developed a low-water flush toilet system for the business sector. It’s toilet system can be integrated into existing drains, thus making for low-cost installation and reducing the water usage in commercial buildings.

The company has secured equity financing to the tune of £16.5m and has global interests stretching as far as the Middle East and Australia.

4. SaveMoneyCutCarbon

Established back in 2012, SaveMoneyCutCarbon serves in a consulting capacity and acts as a singular conduit for all kinds of energy and water saving initiatives.  Catering to both households and companies, SaveMoneyCutCarbon provides consultancy services, analysis, advice and energy-saving product installations. The company also provides a slew of eco-friendly products for home use.

To date, the company has raised £8m in equity funds. Throw in a pre-money valuation of £13.7m and a £3.65m deal with Barclays and you have a company with plans to grow locally and beyond.

5. Enertechnos

This energy efficient startup has developed a new type of electrical transmission cable that relies on capacitance technology to minimise the loss of energy. The end result is an electrical transport solution epitomised by the Captive Transfer System which lets energy travel from power plants to households and end consumers at a much more efficient rate than the archaic power-draining wires used in traditional power grids. This technology can also be integrated with other sustainable energy products like smart grids, electric vehicles and wind farms.

Equity funding to date totals £8.36m, pre-money valuation sits at £22.1m, and the company plans to expand commercial sales, its marketing team and its engineering.

The Future of Gas Boilers – Hydrogen or Heat Pumps?

Due to the international crisis of global warming, the majority of western countries are now set on a course to become carbon neutral and at the Paris Accord, they agreed to achieve this by 2050. This is an impressive feat for countries still so reliant on fossil fuels for major industries like heating and transport.

Residential heating is one area that is currently in the spotlight, for instance, in countries like the UK, it is currently responsible for around one-third of carbon emissions. As a result and understandingly it is set to undergo major reform over the next 10 years.

What’s the problem with current heating?

Heating in the UK is still heavily reliant on fossil fuels, either directly or indirectly. For instance, the vast majority of homes are supplied with natural gas which is burned in fireplaces and gas combi boilers to provide homes with heat.

heating-radiator

The major issue is that burning natural gas releases carbon into the atmosphere, which is a gas that doesn’t leave the atmosphere, resulting in heat being trapped in the atmosphere, leading to global warming.

Therefore, the UK government is looking at low carbon heating alternatives as a route to transforming the current situation, which includes the likes of heat pump, hydrogen boiler and solar.

As Heatable states, residential boilers have already been under considerable scrutiny and the government has banned non-condensing boilers, driving up the efficiency of boilers to above 90%, as well as a total outlaw on all gas boilers in new homes from 2025.

Yet, it’s important to note that most industry commentators consider replacing gas boilers with solar and heat pumps completely unrealistic. Major concerns include their expensive and disruptive installation, as well as their reliability when compared to conventional boilers.

As a result, replacing the fuel is seen as a much more realistic approach with the fuel of choice being hydrogen. This can be fed into the current infrastructure and used with hydrogen-ready boilers, which are almost identical to current natural gas versions.

Hydrogen Boilers vs. Heat Pumps

There are many issues when it comes to the transition from high to low carbon heating technologies. So much so, that the Environmental Audit Committee (EAC) estimated that it would take almost 1,000 years to make the switch if the current trajectories continued.

Even worse, the Committee on Climate Change (CCC) highlighted that it would cost on average £26,000 for each home to install a low carbon heating alternative, rending the whole idea completely unviable.

hydrogen-boiler

The only sensible solution is the adoption of hydrogen fuel as an alternative to natural gas instead. This fuel is able to make use of the current gas networks infrastructure which is already connected to the vast majority of properties.

From an environmental standpoint, hydrogen is also seen as highly desirable.

Why? When hydrogen is burned it produces only vapour and absolutely no carbon dioxide making it ideal for a carbon-neutral future.

Disadvantages of Heat Pumps

As well as that, there are also other issues with heat pumps, of which there are three main types: air source, ground source and hybrid. All of which works by sucking in heat from the surrounding air, ground or water and are able to supply heat to water and central heating.

Hybrid heat pumps are different in that they utilise a boiler to provide supplemental heat if the weather becomes severely cold.

The good point of heat pumps is that they only use small amounts of electricity to operate and combined with the fact that they absorb heat from the environment, they are extremely efficient. In fact, they can achieve energy efficiency ratings exceeding 300%, compared to modern gas boilers that are around 94%.

However, it’s not all positive sadly and heat pumps are unable to provide the same, consistent heat output that gas boilers are able to. For this reason, they are usually installed with oversized radiators and/or underfloor heating and only in properties that are extremely well insulated.

Conclusion

Heating is without a doubt going to change and countries like the UK are going to transition away from gas boilers, but what will win – heat pumps or hydrogen?

It seems that hydrogen has the advantage from a feasibility standpoint, but there’s little doubt that heat pumps will be part of the mix too.

It’s becoming more common for gas boilers to be installed with a hybrid heat pump system.

The first homes fitted with hydrogen boilers and appliances are going to be installed in Fife, Scotland from next year, so progression is certainly accelerating.

Food Waste Management in UK

Food waste in the United Kingdom is a matter of serious environmental, economic and social concern that has been attracting widespread attention in recent years. According to ‘Feeding the 5K’ organisation, 13,000 slices of crusts are thrown away every day by a single sandwich factory. More recently, Tesco, one of the largest UK food retailers, has published its sustainability report admitting that the company generated 28,500 tonnes of food waste in the first six months of 2013. TESCO’s report also state that 47% of the bakery produced is wasted. In terms of GHG emissions, DEFRA estimated that food waste is associated with 20 Mt of CO2 equivalent/year, which is equivalent to 3% of the total annual GHG emissions.

Food-Waste-UK

Globally, 1.2 to 2 billion tonnes (30%-50%) of food produced is thrown away before it reaches a human stomach. Food waste, if conceived as a state, is responsible for 3.3 Bt-CO2 equivalent/year, which would make it the third biggest carbon emitter after China and USA.

What makes food waste an even more significant issue is the substantially high demand for food which is estimated to grow 70% by 2050 due to the dramatic increase of population which is expected to reach 9.5 billion by 2075. Therefore, there is an urgent need to address food waste as a globally challenging issue which should be considered and tackled by sustainable initiatives.

A War on Food Waste

The overarching consensus to tackle the food waste issue has led to the implementation of various policies. For instance, the European Landfill Directive (1999/31/EC) set targets to reduce organic waste disposed to landfill in 2020 to 35% of that disposed in 1995 (EC 1999).

More recently, the European Parliament discussed a proposal to “apply radical measures” to halve food waste by 2025 and to designate the 2014 year as “the European Year Against Food Waste”. In the light of IMechE’s report (2013), the United Nations Environment Programme (UNEP) in cooperation with FAO has launched the Save Food Initiative in an attempt to reduce food waste generated in the global scale.

In the UK, WRAP declared a war on food waste by expanding its organic waste programme in 2008 which was primarily designed to “establish the most cost-effective and environmentally sustainable ways of diverting household food waste from landfill that leads to the production of a saleable product”. DEFRA has also identified food waste as a “priority waste stream” in order to achieve better waste management performance.

In addition to governmental policies, various voluntary schemes have been introduced by local authorities such as Nottingham Declaration which aims to cut local CO2 emissions 60% by 2050.

Sustainable Food Waste Management

Engineering has introduced numerous technologies to deal with food waste. Many studies have been carried out to examine the environmental and socio-economic impacts of food waste management options. This article covers the two most preferable options; anaerobic digestion and composting.

In-vessel composting (IVC) is a well-established technology which is widely used to treat food waste aerobically and convert it into a valuable fertilizer. IVC is considered a sustainable option because it helps by reducing the amount of food waste landfilled. Hence, complying with the EU regulations, and producing a saleable product avoiding the use of natural resources.

IVC is considered an environmentally favourable technology compared with other conventional options (i.e. landfill and incineration). It contributes less than 0.06% to the national greenhouse gas inventories. However, considering its high energy-intensive collection activities, the overall environmental performance is “relatively poor”.

Anaerobic Digestion (AD) is a leading technology which has had a rapidly growing market over the last few years. AD is a biologically natural process in which micro-organisms anaerobically break down food waste and producing biogas which can be used for both Combined Heat & Power (CHP) and digestate that can be used as soil fertilizers or conditioners. AD has been considered as the “best option” for food waste treatment. Therefore, governmental and financial support has been given to expand AD in the UK.

AD is not only a food waste treatment technology, but also a renewable source of energy. For instance, It is expected that AD would help the UK to meet the target of supplying 15% of its energy from renewable sources by 2020. Furthermore, AD technology has the potential to boost the UK economy by providing 35,000 new jobs if the technology is adopted nationally to process food waste. This economic growth will significantly improve the quality of life among potential beneficiaries and thus all sustainability elements are considered.

Why Businesses Need to Reduce Their Carbon Output?

According to a recent Nielsen study, 81 percent of consumers feel strongly that businesses should be taking measures to reduce their impact on the environment. This passion is shared across generations, and it’s safe to say that businesses that have little regard for their corporate social responsibility are significantly less desirable to consumers.

Despite this, a 2018 survey by Carbon Credentials found that only 10 percent of UK businesses had strategies in place to cut carbon emissions. Of those that did, none had a set science-based target in their carbon reduction plan. We know that climate change will devastate the economy and drastically increase the cost of doing business. That’s not even mentioning how it will impact resource scarcity and the global population as a whole.

At the same time, businesses that take the initiative to reduce their carbon footprint can look forward to many more immediate benefits. Here’s why your business needs to conduct a full carbon audit to reduce its carbon output and do to highlight climate action in the sustainability reports.

Cost Savings

Naturally, your expenses go down with your resource usage. From using more efficient equipment to streamlining your transportation operations to recycling office supplies, there are countless measures every business can take to make this happen. Within the first month, you’ll have more money to allocate towards growth – instead of utility bills.

Regulatory and Tax Compliance

Year-on-year, laws are passed to penalise businesses that don’t make an effort to reduce their impact on the environment and reward those that do. In the UK, this includes the Climate Change Levy, the EU Emissions Trading System and capital allowances on energy-efficient equipment, among other schemes.

Public Image

A 2015 Nielsen study of 30,000 consumers found that 66 percent of them would pay more for sustainably manufactured products. Among millennials, that portion increases to 77 percent. Gen Z is known to be even more conscious in this regard. The more your business cares, the more your customers will care about your business.

Employee Morale

In a similar light, going green fosters positive feelings from your employees as well. This has many benefits. For one, your staff will be more productive and motivated to achieve if they know they’re working for a good cause. Additionally, turnover will be reduced as employees will be less compelled to leave a work community that cares.

The Bigger Picture

This should go without saying, but reducing your company’s environmental impact has lasting benefits for your community and the economy as a whole. The likelihood of your long-term success and prosperity is far greater if the environment is in better shape.

What You Can Do

The list of measures your business can take to become more environmentally conscious is quite frankly endless. Get started by taking a look at this post on Utility Bidder, an energy supplier comparison website, about some simple ways that businesses can reduce their carbon output. The internet serves as a wealth of information on this topic.

Implementing greener practises is extremely beneficial to your business and more often than not, it is a dead-simple process. Getting started today will help you reap the benefits and reach your business goals sooner.

Solar Panels – The Advantages and Disadvantages for Homeowners

Solar panels are seeing a huge surge in uptake, with around a million roofs of UK homes now being adorned with them. One of the main reasons for this surge is the interest in renewable energy and climate change. Before you decide to go solar, take time to check out the main advantages and disadvantages as discussed below.

energy efficient technologies

The Advantages of Solar Panels

There is no doubt that one of the biggest advantages of solar panels is the potential to save money on your energy bills, something that is highly attractive when consider alongside the increased cost of living. According to the Energy Saving Trust, most solar panel owners can make savings of between £250 to £600 a year, location-dependent, and will be able to sell any unused energy back to the grid for other users.

Another potential advantage is the ability to sell any unused energy back to the grid via the Smart Export Guarantee (SEG). The SEG allows suppliers to buy any unused energy direct from solar panel owners in return for a cash payment. This not only helps your finances but also supports the demand for renewable energy and lower carbon footprints.

Finally, the other main benefit of installing solar panels is that it is a no-fuss solution that will not need excessive maintenance, nor will it make any noise when they are in use. Plus, most installers offer a 25-year guarantee on all the panels in case of any issues.

The Disadvantages of Solar Panels

Despite offering so many benefits, there are disadvantages that you will need to consider before forging ahead with solar panel installation. The first one is the initial cost of the system that you will need to invest in to get your solar panels up and running. Most homes can expect to pay over £6500 for solar panels even with the ongoing drop in prices as they become more popular.

Next, you will need to be realistic about the amount of energy your solar panels will create with the British weather. Solar panels are always going to work better on bright sunny days, meaning that your production will slow on cloudy days and through the winter and produce less energy for you to send back to the grid.

Finally, solar panels are not suitable for every home, and you may find that your roof does not face the right way or have the right angle to accommodate the panels. Even if you do have the right roof, your solar panels will take up lots of space, so you will need to work out if your roof is big enough to offer the supply that you need.

Solar Panels – a Summary

Getting to grips with all the pros and cons can be daunting, so we have summarised them below for quick reference:

Pros Cons
Offers a genuine saving on energy bills Takes a long time to make any money back
Reduce your carbon footprint Can be expensive to install
Simple to maintain Hard to move once installed
Range of financial support options Weather can reduce performance
Several types of panels to choose between Can look unattractive
Make cash from the energy you do not use Needs lots of space
Noiseless once installed Not suitable for all roofs

If you are keen to proceed with solar panel installation, then take the time to search for the best deals and check out all the financial support packages that may be open to you as this will help you get the best return on your investment for years to come.

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.

electrical-waste-uk

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 electrical wastes from households in the UK 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.
