Some countries have achieved considerable success in solid waste management. But the rest of the world is grappling to deal with its wastes. In these places, improper management of solid waste continues to impact public health of entire communities and cities; pollute local water, air and land resources; contribute to climate change and ocean plastic pollution; hinder climate change adaptation; and accelerate depletion of forests and mines.
Compared to solid waste management, we can consider that the world has achieved significant success in providing other basic necessities like food, drinking water, energy and economic opportunities. Managing solid wastes properly can help improve the above services further.
Composting of organic waste can help nurture crops and result in a better agricultural yield. Reducing landfilling and building sanitary landfills will reduce ground and surface water pollution which can help provide cleaner drinking water. Energy recovery from non-recyclable wastes can satiate significant portion of a city’s energy requirement.
Inclusive waste management where informal waste recyclers are involved can provide an enormous economic opportunity to the marginalized urban poor. Additionally, a good solid waste management plan with cost recovery mechanisms can free tax payers money for other issues. In the case of India, sustainable solid waste management in 2011 would have provided
9.6 million tons of compost that could have resulted in a better agricultural yield
energy equivalent to 58 million barrels of oil from non-recyclable wastes
6.7 million tons of secondary raw materials to industries in the form of recyclable materials and livelihood to the urban poor
Solid waste management until now has only been a social responsibility of the corporate world or one of the services to be provided by the municipality and a non-priority for national governments. However, in Mumbai, the improperly managed wastes generate 22,000 tons of toxic pollutants like particulate matter, carbon monoxide, nitrous and sulfur oxides in addition to 10,000 grams of carcinogenic dioxins and furans every year. These numbers are only for the city of Mumbai. This is the case in cities all across the developing world. There are numerous examples where groundwater is polluted by heavy metals and organic contaminants due to solid waste landfills.
Solid waste management expenditure of above $ 1 billion per year competes with education, poverty, security and other sustainable initiatives in New York City. Fossil fuels for above 500,000 truck trips covering hundreds of miles are required to transport NYC’s waste to landfills outside the city and state. Similarly, New Delhi spends more than half of its entire municipal budget on solid waste management, while it is desperate for investments and maintenance of roads, buildings, and other infrastructure.
Solid waste management is not just a corporate social responsibility or a non-priority service anymore. Improper waste management is a public health and environmental crisis, economic loss, operational inefficiency and political and public awareness failure. Integrated solid waste management can be a nation building exercise for healthier and wealthier communities. Therefore, it needs global attention to arrive at solutions which span across such a wide range of issues.
Bahrain has the distinction of being one of the highest per capita municipal solid waste generators worldwide estimated to be more than 1.80 kg per person per day. Infact, Bahrain produces largest amount of waste per person among GCC countries despite being the smallest nation in the region. Rising population, high waste generation growth rate, limited land availability and scarcity of waste disposal sites has made solid waste management a highly challenging task for Bahrain’s policy-makers, urban planners and municipalities.
Municipal Solid Wastes in Bahrain
Bahrain generates more than 1.2 million tons of solid wastes every year. Daily garbage production across the tiny Gulf nation exceeds 4,500 tons. Municipal solid waste is characterized by high percentage of organic material (around 60 percent) which is mainly composed of food wastes.
Presence of high percent of recyclables in the form of paper (13 percent), plastics (7 percent) and glass (4 percent) makes Bahrain’s MSW a good recycling feedstock, though informal sectors are currently responsible for collection of collection of recyclables and recycling activities
The Kingdom of Bahrain is divided into five governorates namely Manama, Muharraq, Middle, Southern and Northern. Waste collection and disposal operation in Bahrain is managed by a couple of private contractors. The prevalent solid waste management scenario is to collect solid waste and dump it at the municipal landfill site at Askar.
Askar, the only existing landfill/dumpsite in Bahrain, caters to municipal wastes, agricultural wastes and non-hazardous industrial wastes. Spread over an area of more than 700 acres, the landfill is expected to reach its capacity within the next few years. The proximity of Askar landfill to urban habitats has been a cause of major environmental concern. Waste accumulation is increasing at a rapid pace which is bound to have serious impacts on air, soil and groundwater quality in the surrounding areas.
The Kingdom of Bahrain is grappling with waste management problems arising out of high population growth rate, rapid industrialization, high per capita waste generation, unorganized SWM sector, limited land resources and poor public awareness.
The government is trying hard to improve waste management scenario by launching recycling initiatives, waste-to-energy project and public awareness campaign. However more efforts, in the form of effective legislation, large-scale investments, modern SWM technology deployment and environmental awareness, are required from all stake holders to implement a sustainable waste management system in Bahrain.
Most people want to do what they can to help the environment. After all, this planet is our home, and it doesn’t benefit us if we’re destroying it. That being said, it can be incredibly hard to live an eco-friendly life. It often requires time, money, and resources that the average person doesn’t have. Luckily, there are a few ways that you can live a more eco-friendly life that don’t require any major changes or sacrifices. These are changes that most people can easily make. And, as with most things, change tends to start at home. That’s why, in this post, we’ll be discussing four ways that you can make your house more eco-friendly.
1. Support eco-friendly services
We all make use of services when it comes to our house. We constantly call people in to fix things, or to clean things. So, why not rather support a company that isn’t harming the earth?
Other than doing some research and making the switch, this will require minimal effort from your side but can make a big difference when it comes to the environment. For example, next time you need your carpets cleaned, why not try an earth-friendly carpet cleaning system?
It’s a well-known fact that recycling is one of the most common topics that are brought up when it comes to living a more eco-friendly life. And yet, many people don’t recycle. That’s because many of them don’t know what recycling entails.
We’re not saying you need to make homemade paper out of your old scraps of paper (although you absolutely can, if the idea interests you) but simply separating your recyclable items from the non-recyclable items will make it much better for recycling companies to do their jobs. If you need more information, click here for a list of what can be recycled.
3. Make use of alternative energy sources
Every single day, nearly every person on this planet uses some form of electricity, and a lot of it negatively impacts the world. That’s why more and more people are being encouraged to make the switch to alternative or renewable energy sources. Wind energy is a popular choice, but it’s not suitable for all regions.
Solar panels, on the other hand, can be utilized by most households. While solar energy used to be a rare luxury that few could afford, the increase in demand means that it’s now more affordable than ever.
4. Make your own compost
Compost is great for various reasons. It’s good for the environment, it means that you waste less product, and it’s great for your garden. So, with all that in mind, we can’t think of a single reason not to make your own compost!
Many people shy away from composting because they find the idea of it unappealing, but the truth is that it can be a very rewarding thing. The least you can do is to try composting – if it’s not for you, you can be eco-friendly in other ways!
Waste management is a serious problem in Nigeria, and Delta State is no exception. It is a problem that starts at a cultural level: many of the populace believe that once they remove waste from their homes it is no longer their concern. It is a problem that starts at a cultural level: many of the populace believe that once they remove waste from their homes it is no longer their concern, and you often see people disposing of their household waste in the streets at night. Once the waste gets out into the streets, it’s perceived as the duty of the government to handle it.
However, I have never yet heard of any Nigerian politician making waste management a feature of his or her manifesto during the election campaign process. Having said that, a few of Nigeria’s political leaders deserve to be commended for coming to terms with the fact that waste has to be managed properly, even if such issues were far from their minds when they entered political office.
Legislation and Framework
Nigeria does have a waste legislation framework in place. Its focus has been on the most toxic and hazardous waste: partly in response to some major pollution incidents in the 1980s, the government took powers in relation to Hazardous Waste in 1988. In the same year, the Federal Environmental Protection Agency was established – and was subsequently strengthened by the addition of an inspectorate and enforcement department arm in 1991, with divisions for standard regulation, chemical tracking and compliance monitoring. These laws have since given rise to regulations and guidelines pertaining to environmental and waste management issues.
Under our laws, waste management in each state is the duty of the local governments that fall within it, but few are taking an active approach to implementing and enforcing the sensible measures that the regulations require. A small number of states have taken over this task from local government, and Delta State’s decision to do this has led to significant new investment in waste management.
One of the fruits of that investment is the Delta State Integrated Waste Management Facility at Asaba for treating both household and clinical waste generated locally. It was developed when the Delta State government decided to put an end to the non-sustainable dumping of waste in Asaba, the state capital.
Integrated Waste Management Facility at Asaba
It is described as an integrated waste management facility because it includes a composting department, a recycling department and a (non-WTE) incineration department. Trucks carrying waste are weighed in as they come into the facility. From the weigh bridge, they move to the relevant reception bay – there are separate ones for household and clinical wastes – to tip their load, and are then weighed again on the way out.
Medical waste is taken directly for incineration, but household wastes are sent along conveyors for sorting. Recyclables and compostable materials are, so far as possible, separated both from other waste and from one another. Each recyclable stream ends up in a chamber where it can be prepared for sale. The compostable materials are moved to the composting section, which uses aerated static pile composting.
The remaining waste is conveyed into the three incinerators – moving grate, rotary kiln and fixed end– for combustion. The resulting ash is recycled by mixing it with cement and sharp sand and moulding it into interlocking tiles. The stacks of the three incinerators are fitted with smoke cleaning systems to reduce emissions. The process produces wastewater, which is channelled to a pit where it is treated and reused. Overall, 30% of the waste is composted, 15% recycled and 55% incinerated.
There are many examples of sophisticated waste infrastructure being built in developing countries, but failing because the necessary collection systems were not in place to support them. To ensure that this problem is avoided at Asaba, the Delta State government is working with a group known as the Private Sector Participants (PSP).
Each member of this group has trucks assigned to them and has been directed to collect household waste from different parts of the city, for delivery to the facility for treatment. The arrangements made by each PSP are different: some collect from outside individual properties, and some from communal sites; most collect waste that is found in the streets; and while each is subsidised by the state, households also have to pay towards the cost.
Before the Asaba waste management facility was developed, most of the wastes generated in Asaba were disposed of at a dumpsite just adjacent to the Delta State Airport. This created a pungent odour, as well as visual disamenity for people nearby. A great deal of remediation work is now taking place at the dumpsite, which is vastly improving the local environmental quality.
War on Waste
Of course, although this is an improvement there remains more to do. First on the list is education. People do not know how sustainable waste management can impact positively in their lives, reducing their exposure to toxins as well as improving their surroundings. Nor do they understand that recycling a beverage can or a plastic bottle will cost less than producing one from virgin materials and will have a lesser environmental impact. There remains a good deal of cultural change and environmental education that is needed before people will stop throwing waste and litter on the streets – but there are few countries where, to some extent, the same would not be true.
Next is the lack of infrastructure. Nigeria has 36 states and a federal capital, yet the facility in Asaba is the first publicly commissioned one of its kind in the country; there are also some privately owned incinerators that a few companies in Port Harcourt use to treat wastes from vessels (ships), hospitals and industries. Lagos state and Abuja are relatively advanced, simply by virtue of having put in place a few managed landfills, but they are still far from having the level of facility that Asaba can now boast.
The backbone of Asaba’s progress is the state government’s commitment to put a proper waste management solution in place. We’ve seen the impact in the form of infrastructure, collections and remediation, and law enforcement work is starting to change people’s perception about waste management in Delta State. At the moment, plans are being concluded to setup another facility in Warri, Delta State’s industrial hub, which will be twice the size of the Asaba facility.?
My hope is that the progress made by Delta State will be a beacon for other states’ governments. The example we are providing of cleaner, hygienic, more environmentally responsible waste management, and the positive changes that is bringing about, should inspire new development elsewhere in the country, which could equal or even exceed Delta State’s results. So whilst Nigeria’s track record on waste may leave a lot to be desired, the path ahead could be a great deal more promising.

When 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.
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.

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 and save 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 program about which you can read in the essay about recycling, 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
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.
Millions and billions of garbage are accumulated every year. In America alone, each individual produces up to 4 pounds of waste material every day. Improper disposal of this garbage is harmful not only to you but also to everyone around you. Waste from landfills can emit greenhouse gases, pollute the soil, and can contaminate your drinking water.
However, in a simple way, such as recycling, you can make a difference. You can recycle your garbage in various ways, including reselling, donating, collecting, manufacturing, etc. Recycling is a lifestyle you can choose that requires a vast amount of dedication and a sense of responsibility.
Here are some tips and tricks that can help you start your recycling journey.
What You Can Recycle
First, you need to distinguish what garbage you can and cannot recycle.
Plastic – Any plastic containers and bottles with the recycling symbol, and inside are the numbers 1 or 2.
Paper Products – Items including phonebooks, magazines, mails, newspapers, food boxes, cardboard boxes, and printer paper.
Glass – Objects like food containers, bottles, and jars, which are emptied and rinsed.
Metal – Mainly aluminum cans, steel cans, tin, and other metals as long as it’s also empty and rinsed.
There are still more items to be included in the list, feel free to read the label or go online for them. It’s good to make it a habit to check if an item is recyclable or not.
Purchase Your Recycling Bins
After knowing what garbage is recyclable and non-recyclable, you can now buy your recycling bins. You can shop in malls or other marketplaces that offer bins in your desired size and shape at affordable prices. Some bins have a recycling logo that would help you to easily distinguish it from your other trash cans.
The basic rule in how many bins you should acquire depends on how many trash cans you have in your household. Also, set up your recycling bins next to your trash cans so that every time you throw an item away, you will be reminded to check if it’s recyclable or not. Remember not to use plastic bags in recycling because they are not recyclable.
Aside from your home, you can also keep recycling bins in your car and your office at work. Wherever you are, you can always sort and recycle your garbage.
Find Your Local Drop-Off Location
Depending on where you live, there may be different rules on what you can recycle and how to prepare your recycled items. Moreover, public drop-off areas are also important information to know together with the local garbage collection schedule.
Some states would allow you to leave your recycled items in the curbside, but if not, be sure to know where the designated areas are so that you can dump your recyclables before garbage collectors pick them up. The collection schedule could either be once a week or once every other week. It wholly depends on where you live.
Be sure to inquire to your local government or information desk about these rules and instructions before you start recycling. Print out the vital information and instructions, and post them somewhere visible so that you can’t forget about them.
Other Actions to Consider
Recycling your garbage helps in reducing your household waste and lowering your carbon footprint. But besides recycling, there are many other activities and practices you can do to help the society and the environment more. Remember to reduce, reuse, and recycle the items in your household instead of immediately throwing them out.
You can avoid buying or using single-use plastics to reduce the waste you produce. Another trick is to use recyclable bags instead of paper and plastic bags. Utilize your jars for your leftovers instead of plastic containers. You can also create your garden fertilizer by using food waste and other compostable garbage to set up a compost pile.
However, for wastes such as expired medicines, one should not, in any way, recycle and reuse expired or unused medicines as they can pose a risk to one’s health and safety. Throwing it anywhere is also harmful to the environment.
There’s a specific disposal process you must follow, which includes mixing the medicine with cat litter or referring to the FDA’s Flush List. Visit BuzzRx to learn more about proper medicine disposal.
The way you live can impact the world and the environment. By recycling, you can help lessen waste, conserve resources, and not contribute to the pollution already prevalent in our world. No matter how tedious recycling can be, remember that it will be developed into a good habit that will help improve the society, environment, and especially yourself.
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.
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. For those that are bill tracking, it is important to note that 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.
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.
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. Instead of plastic toothbrush, use a bamboo toothbrush from Ecoy.
Around 5% of the world’s CO2 emissions are caused by concrete production, so finding sustainable alternatives is essential to slowing down climate change. Fortunately, there are plenty of materials out there which are perfect for mass home construction, without the same ecological damage. If you want to continue to do meaningful things, such as travel the world or live in safe and comfortable accommodation, then finding alternative building materials is the route to doing this sustainably.
Hemp Concrete Substitute
By compacting hemp and lime, it is possible to create a building block comparable to concrete. Unlike concrete, however, hemp absorbs carbon dioxide rather than emits it. This means that during the production process, 1m3 of hemp concrete wall will suck up 165kg of CO2. It is just as durable and robust as regular concrete, but will require cannabis legalisation before manufacture can begin.
Nigerians are building fireproof, bulletproof, and eco-friendly homes with plastic bottles and mud
In countries where the plant is already legal to produce, then the switch to hemp alternative building material should begin immediately. Hemp plastic is an attractive sustainable building material which holds great potential worldwide.
Bamboo and Straw
Wood has long been a popular home building material, but not all plants are equally green. Bamboo has the quickest regrowth time of any plant, meaning that it can be replaced as quickly as it is cut down. It is strong and durable. Meanwhile, straw, when packed tightly, is a perfect eco-friendly insulation material. Together, this makes the most environmentally conscious wooden cabin.
In the debate of manufactured vs modular cabins, the latter tends to be preferred due to its rigidity and durability, while the former is more affordable. By constructing modular bamboo cabins, however, you are able to produce a long-lasting, energy efficient home at a much cheaper cost.
Reused Plastic Waste
The world purchases a million plastic bottles a minute or 480 billion a year. We need to seriously start thinking about how we can reduce our consumption of single use plastics, but also what to do with the waste in the meantime.
One thing that the bottles can be used for is the construction of houses. When filled with sand and stacked together, they form a durable and insulating wall. In some countries, this is being used as a way to bring affordable housing to those living in poverty. It is certainly a creative way to build homes without using more of the Earth’s precious resources.
There are so many alternatives to concrete out there. Governments and construction companies need to come together to move towards sustainable building practices. This will help to ensure that everyone has a safe place to call home, while recycling resources and cleaning the carbon dioxide out of the atmosphere.
Solid waste management is one of the major environmental problems threatening the Kingdom of Morocco. More than 5 million tons of solid waste is generated across the country with annual waste generation growth rate touching 3 percent. The proper disposal of municipal solid waste in Morocco is exemplified by major deficiencies such as lack of proper infrastructure and suitable funding in areas outside of major cities.
According to the World Bank, it was reported that before a recent reform in 2008 “only 70 percent of urban wastes was collected and less than 10 percent of collected waste was being disposed of in an environmentally and socially acceptable manner. There were 300 uncontrolled dumpsites, and about 3,500 waste-pickers, of which 10 percent were children, were living on and around these open dumpsites.”
It is not uncommon to see trash burning as a means of solid waste disposal in Morocco. Currently, the municipal waste stream, including hazardous wastes, is disposed of in a reckless and unsustainable manner which has major effects on public health and the environment. The lack of waste management infrastructure leads to burning of trash as a form of inexpensive waste disposal. Unfortunately, the major health effects of burning trash are either widely unknown or grossly under-estimated to the vast majority of the population in Morocco.
The good news about the future of Morocco’s MSW management is that the World Bank has allocated $271.3 million to the Moroccan government to develop a municipal waste management plan. The plan’s details include restoring around 80 landfill sites, improving trash pickup services, and increasing recycling by 20%, all by the year 2020. While this reform is expected to do wonders for the urban population one can only hope the benefits of this reform trickle down to the 43% of the Moroccan population living in rural areas, like those who are living in my village.
Needless to say, even with Morocco’s movement toward a safer and more environmentally friendly MSW management system there is still an enormous population of people including children and the elderly who this reform will overlook. Until more is done, including funding initiatives and an increase in education, these people will continue to be exposed to hazardous living conditions because of unsuitable funding, infrastructure, policies and education.
