Waste is the result of collective failure from public, legislative rules, lack of funds and technical support. Public awareness and proper knowledge of waste management and end use of different types of waste, health effects, environmental problems and economic issues that are related to waste management is very important for successful execution of any waste management related practices. Everyone needs to get better knowledge, proper understanding of waste management issues and their practices to curb it. Basic training needs to be initiated from governments in this regard, which can be very effective. Poor knowledge can make the best planned technique questionable.
The increasing cost of waste disposal is a cause of major concern in developing nations
In developing countries, participation level of most citizens in waste management is very low, with residents in urban areas are not actively involved in the process of waste management. Even though it’s low, but very beneficial for future prospect and for more meaningful involvement of majority of public in waste management practices.
People should be educated about sorting out waste based on their type e.g. recyclable waste, hazardous waste, green waste etc. Majority of people across the world are not aware of waste as recycling material, amazingly most of them think plastic is recyclable waste. Involving people who are unaware of waste management practice is extremely difficult.
In developing countries, practices of waste management are usually carried by poor, for their survival. It has been estimated that 2% of population in Asia, Latin America and Africa are dependent on waste for their livelihood. Family organized, or individual manual scavengers are often involved with waste management practices with very limited supportive network and facilities with increased risk of health effects. Also, this practice prevents their children from further education.
Despite the bad consequences, it should be kept in mind that this practice keeps them employed and provide livelihood in countries with high unemployed population. But measure need to be taken to provide their better lifestyles, social behaviour towards people involved in waste management practices, provide them with facilities to reduce their health-related risk and increase their working efficiency.
In developing countries, where government support for waste management is scarce, people need to come strongly against their local municipal office or government if they see things are not changing and stacks of waste are piling up. They should protest to protect their environment, health and keep living secure and healthy for their children.
Since catapulting to the frontlines of news headlines and global consciousness, climate change is one of the most talked about and concerning topics of the modern age. Fortunately with this shift in cognition, manufacturers all across the globe have banded together to create green products in hopes of a more eco-friendly future. It’s these very products that can transform any business from a wasteful guzzler to a green success. With this guide, we’ll walk you through how you can incorporate sustainability into your daily business practice.
1. LED bulbs
Switch out the incandescent light bulbs with CFL or LED bulbs for a longer-lasting and more energy-efficient brilliance. Compact-fluorescent (CFL) and LED light bulbs tend to carry higher price tags than the average fluorescent bulb, however they offer a far more attractive projected lifespan than typical fluorescent bulbs which tend to offer 1,200 hours of light.
LED bulbs, on average, cost around $5 and offer 25,000 hours of light, while CFL light bulbs cost about $2 and offer 10,000 hours of projected lifespan. Not only are CFL and LED lights more practical from a sustainability standpoint, but they will also save you thousands on your business’s electric bill.
2. Biodegradable Kitchen Supplies
Using biodegradable kitchen supplies to save on plastic waste. Unless your office is the type of place where employees keep personal dishes in the kitchen cupboard, you will likely need to keep a stash of utensils, cups, and plates on deck for any catered lunches or work parties.
Recycling ink cartridges is a great practice to put in place for businesses equipped with a number of printers. Believe it or not, the vast majority of discarded ink cartridges end up in harmful, toxic landfills that eventually end up in our oceans. Ink cartridge recycling is the most eco-friendly solution to this preventable problem. There are a number of simple ways to take those empty cartridges off your hands and into the hands of a trusted recycler:
Find a local office supply store: Did you know most office supply stores offer recycle programs? Check online or call in to see if they accept ink cartridges.
Consider refilling original cartridges: Do a bit of research on the brand of your empty ink cartridge. You may find that they are able to refill your cartridge and you won’t ever have to worry about tossing them!
4. Opening windows
Opening up windows is an easy solution to a stuffy, warm office. When people are packed like sardines into their tiny cubicles, the air can quickly become stale and stifling. Instead of wasting money and energy on air conditioning, open a few windows to let fresh air flow in.
Air conditioners put hydrofluorocarbons, a type of greenhouse gas emission, into the environment—so while you may feel refreshed, the earth is further harmed. Reduce your business’ contribution by saving the AC for the more-unbearable summer days.
5. Adopt renewable energy
Invest in renewable energy sources for a long-term, energy-efficient, and eco-friendly power solution. Every year, we see more and more solar panels sitting atop rooftops, which means the time to invest in solar panels is now. By converting sunlight into a sustainable power source, solar panels are the greenest source of energy on the planet today. Solar energy can be used heat buildings and provide energy to power lights on.
6. Make use of post-consumer waste
Turning to post-consumer waste (PCW) to escape the cycle of high-volume paper waste is an exceptional solution for any company that uses a lot of paper. PCW paper is paper re-made at recycling facilities. According to the Environmental Paper Network Paper Calculator, PCW paper saves on
5,610 gallons of water
5,000,000 BTU of energy
376 pounds of solid waste
1,035 pounds of CO2 greenhouse gas emissions
In 2021, there are no more excuses for why a business is stuck in the past. The future can be a bright one if we all put our best foot forward and make the effort to make our spaces greener!
The importance of saving water cannot be understated, especially as many countries around the world are facing drought conditions. Of course, there is an endless list of small changes you can make as a homeowner to improve the water-saving efficiency of your home, and they add up to a potentially significant difference in the long-term.
1. Repurpose Water
A staggering amount of water literally goes down the drain each day, when there are plenty of smart, safe ways to conserve as much of it as possible. Your bathroom is a key contributor to single-use wastage, and by keeping a container on the floor of your shower you can collect liters with each use. Meanwhile, in the kitchen, even seemingly small things like using a container to catch the water used in washing fresh produce can make a difference over time.
2. Get Smart About Lawn Care
It’s a common misconception that maintaining a healthy lawn requires a plentiful supply of water. Even during water-restricted periods, keeping your grass green is possible – you just have to get clever about your lawn care practices. Depending on the severity of restrictions, you may only be allowed to water your garden and lawn on certain days and at set times of day, and this will probably be enough, as long as you follow a few guidelines.
If possible, it’s best to water your plants and grass in the evening so that the water has plenty of time to soak into the soil and roots without the threat of evaporation. In case you’re unsure whether to water or not, feeling the topsoil for dryness will give you the best indication. Another interesting option for a smart and healthy lawn is to go for artificial grass.
3. Use the Half-flush
The second button on the toilet is more than just an aesthetic feature. In fact, the half-flush button can save as much as 70% of the water used in a full flush, owing to the difference in flushing design. A wash-down design and a large trap way make it easier for waste to flow down the drain, meaning less water is required. If you can afford to replace an old, inefficient system, you stand to save a lot of water (and by extension, money) in the long-term.
4. Use Dual Sinks
Washing dishes by hand gets a bad rap in terms of water efficiency, and it often uses more water than a dishwasher, but it’s possible to prevent a great deal of wastage by using your sink effectively. If you have a double-barreled sink, using one side for washing and the other for rinsing will allow you to wash an unlimited load without needing to refresh the water.
5. Check the Ratings
Every water-using device has an efficiency rating, and choosing a well-rated model will help you prevent unnecessary wastage at the source. In some countries, large devices like dishwashers and washing machines come with a star rating to give an indication of their efficiency, and even if they don’t, you can still do your own comparative checks.
In the US, the toilet is typically the biggest source of water wastage, followed by the shower and faucets, but with modern water-efficient designs like water-saving vacuum toilets and low-flow showerheads, much of that water could be preserved.
6. Install Water-Saving Faucets
The only thing more efficient than collecting and re-using run-off from the shower is using less water at the source, and the right faucet can help with that. You can use touchless faucets in your kitchen as well as it can save a lot of water. According to myhomeneedz, a touchless kitchen faucet can save up to 20% water compared to normal faucets.
Just like dishwashers and washing machines, faucets often come with a water-efficiency rating, but they can also be made more eco-friendly through simple add-ons like aerators. An aerator installation is a perfect project for eco-conscious lovers of DIY – once it’s done, the difference will be practically undetectable, and you’ll be saving liters without even trying.
7. Buy Smaller Machines
Devices like dishwashers and washing machines are becoming more water-efficient with each passing year, but the fact remains that large machines tend to use much more water than their smaller counterparts. A smaller device will also make it easier to commit to only running full loads, since it will take less time to fill.
You might even consider investing in a double-gallon dishwashers, designed to run smaller loads with half the amount of water – there’s plenty of technology available to help in your quest to use less.
8. Install a Water Tank
If you have the money and the space available on your property, a water tank is one of the best long-term water-saving investments you can make. Even the average backyard water tank allows for the collection of several hundred liters, which is more than enough to keep your yard in good condition or fill your bathtub many times over. Tanks can be expensive to buy, but the savings you stand to make on your water bills will make it all worthwhile.
Fresh drinking water is a precious resource, and developing efficient usage habits has never been more important. The bottom line is that saving water isn’t difficult, and with a few tips and tricks up your sleeve, you’re fully-equipped to start doing your bit for the environment and the world as a whole.
There is a broad consensus that human beings have the right to enjoy an environment suitable for personal development. In reality, this right is also a duty since it requires for its viability that human activity itself does not impede the enjoyment of this right. It is moving from mere enforceability to the sphere of responsibility and duties.
But to enter into the logic of responsibility implies for those of us who are culturally conditioned to advance towards a cultural change.
In today’s entry, we will carefully analyze our responsibilities towards our environment and nature itself. To do so, we will analyze the different aspects of environmental law and our responsibilities to respect it. Here are the four most vital components of that law.
Human Responsibility in the Natural Environment
An ecological cultural change is nourished by our modern-day behaviors. Like in many cultures, welcoming the gift of creation invites us to continue to show the love that orients and promotes all lives. However, this gift allows and also demands respect for the equilibrium of the environment itself.
This balance is not only the fruit of a simple random and fortuitous evolutionary course but must be recognized as a gift that makes human life as a whole possible. A rupture of this dynamic is what scientists are warning about, the abuse of the environment. Introducing changes that break its balance, such as the current climate change process resulting from human activity and a cultural model that allows the abuse of resources. Thus, disrupting the natural balance.
Responding to this imbalance implies recognizing and practicing some duties that are marginalized in the present culture.
Our Responsibility of Conservation
The first responsibility is the conservation of creation. Today, witnessing the signs of the globalized ecological crisis throughout the planet, it is clear that the appropriate framework for “cultivation” is guardianship or conservation.
Without conservation, there can be no responsible and fair human cultivation. From this understanding, nature’s cultivation cannot lead to its “exploitation” because it cannot be abused, breaking its balance. A current concretization of this responsibility implies fighting against climate change and the various ecological disorders.
The signs of a development that has not always known how to protect nature’s delicate balances are evident when talking about air pollution. Before it is too late, severe measures must be taken, not only when writing an air pollution essay or article, but in real-life, to re-establish a strong alliance between man and the earth.
Therefore, we need a decisive “yes” to the protection of creation and a strong commitment to reverse the trends that could lead to situations of irreversible degradation.
The Responsibility not to Alienate Nature
The second responsibility that lies in our hands is to “respect the grammar of nature”. Nature is not an “untouchable taboo.” The natural environment is not only matter subjectively available to human beings, but an admirable work of nature itself that carries within itself a “grammar” that indicates purpose and criteria for intelligent, non-instrumental, and arbitrary use.
Today, many harms to development come from these distorted ways of thinking. Completely reducing nature to a set of simple factual data ends up being a source of violence towards the environment, provoking behaviors that do not respect the nature of man himself.
The latter, insofar as it is composed not only of matter but also of the spirit, and therefore rich in meanings and transcendent ends, has a normative character even for our culture.
Integration of Justice
Third, the need to integrate ecological justice and social justice. This need implies using resources that are respectful of nature and equitable with present and future human rights. Thus, the responsibilities we have towards the environment are related to those we have towards the person and his relationship with others. We cannot demand some and violate others. This is a severe antinomy of today’s mentality and praxis, which debases the person, disrupts the environment, and damages society.
For example, the desertification and productive impoverishment of some agricultural areas is also the fruit of the impoverishment of their inhabitants who suffer resource consumption damages. These have been crucial topics that show up regularly in a water pollution essay by environmental protection advocates due to the impact it causes in our occidental society. This impoverishment includes energy, air, and water pollution, which damage their natural environment (the effects of climate change on their lands, for example) and the inequitable consumption in its enjoyment and hoarding by influential minorities of humanity. The fruit of social justice must be held at peace among our societies and also with nature.
Social injustice is the occasion for social war and natural destruction. Many natural resources are devastated by wars. Peace among peoples and between peoples would also make it possible to safeguard nature more effectively. The hoarding of resources, especially water, can lead to serious conflicts between the populations concerned. Thus, a peaceful agreement on the use of resources can safeguard nature and, at the same time, the well-being of the societies concerned.
The fourth responsibility is to improve efficiency and sustainability when dealing with nature. Responsible governance of creation implies, among other things, improving energy efficiency and the search for alternative energies to reduce their harmfulness to the environment and the harm to humanity itself. But it has to be framed in a global project of relationship with nature in the key of “alliance between human being and a healthy environment,” which adequately weighs the path to the future. That considers the approach to be followed in each aspect.
This is a global responsibility: The international community and each government must know how to counteract effectively those ways of using the environment that is harmful to it. And the competent authorities must also make the necessary efforts to ensure that the economic and social costs arising from the use of common environmental rights and resources are recognized transparently and borne entirely by those who benefit, not by others or by future generations.
The protection of the environment, resources, and the climate require that all international decision-makers act together and demonstrate a readiness to act in good faith, respect for the law and solidarity with the weaker regions of the planet.
Responsibilities that can help us to assume our responsibility towards ourselves. Towards the present and future of humanity, and towards the whole of creation.
Out of all the measures that are necessary in addressing India’s impending waste management crisis, the most efficient will be changes at the national policy and planning level. It is well-known among the small but growing waste management sector that urban India will hit rock bottom due to improper waste management.
Unfortunately, they think such a crisis is required to bring about policy changes, as they generally tend to happen only after the damage has been done. This attitude is unfortunate because it indicates a lack of or failed effort from the sector to change policy, and also the level of India’s planning and preparedness.
An average of 32,000 people will be added to urban India every day, continuously, until 2021. This number is a warning, considering how India’s waste management infrastructure went berserk trying to deal with just 25,000 new urban Indians during the last decade. The scale of urbanization in India and around the world is unprecedented with planetary consequences to Earth’s limited material and energy resources, and its natural balance.
Rate of increase in access to sanitation infrastructure generally lags behind the rate of urbanization by 33% around the world; however, the lack of planning and impromptu piecemeal responses to waste management issues observed in India might indicate a much wider gap. This means urban Indians will have to wait longer than an average urban citizen of our world for access to proper waste management infrastructure.
The clear trend in the outbreak of epidemic and public protests around India is that they are happening in the biggest cities in their respective regions. Kolkata, Bengaluru, Thiruvananthapuram, and Srinagar are capitals of their respective states, and Coimbatore is the second largest city in Tamil Nadu. However, long term national level plans to improve waste management in India do not exist and guidance offered to urban local bodies is meager.
Apart from the Jawaharlal Nehru National Urban Renewal Mission (JnNURM), there has been no national level effort required to address the problem. Even though JnNURM was phenomenal in stimulating the industry and local governments, it was not enough to address the scale and extent of the problem. This is because of JnNURM is not a long term waste management financing program, sorts of which are required to tackle issues like solid waste management.
Are Cities Hands-tied or is Change Possible?
In the short term, municipal corporations have their hands tied and will not be able to deliver solutions immediately. They face the task of realizing waste management facilities inside or near cities while none of their citizens want them near their residences. Officials of Hyderabad’s municipal corporation have been conducting interviews with locals for about eight years now for a new landfill site, to no avail.
In spite of the mounting pressure, most corporations will not be able to close the dumpsites that they are currently using. This might not be the good news for which local residents could be waiting, but, it is important that bureaucrats, municipal officials and politicians be clear about it. Residents near Vellalore dump protested and blocked roads leading to the site because Coimbatore municipal officials repeatedly failed to fulfill their promises after every landfill fire incident.
Due to lack of existing alternatives, other than diverting waste fractionally by increasing informal recycling sector’s role, closing existing landfills would mean finding new sites. Finding new landfills in and around cities is nearly impossible because of the track record of dumpsite operations and maintenance in India and the Not in My Backyard (NIMBY) phenomenon.
However, the corporations can and should take measures to reduce landfill fires and open burning, and control pollution due to leachate and odor and vector nuisance. This will provide much needed relief to adjacent communities and give the corporations time to plan better. While navigating through an issue as sensitive this, it is of the utmost importance that they work closely with the community by increasing clarity and transparency.
Despite their inability to properly manage wastes, the majority of municipal officials consider waste as “wealth” when approached by private partners. Therefore, a significant portion of officials expect royalty from private investments without sharing business risk.
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.

Environmental concerns are more widespread than they ever have been, thanks to high-profile documentaries, a raft of alarming science, and some determined activism from green pressure groups. And these concerns are helping to shape the modern home, too.
There are myriad ways in which the environmental impact of your home can be lessened. Some of these involve major investment and upheaval; others, however, offer a considerable return on just a little bit of effort.
Swapping out older halogen-style light bulbs for newer LED-based ones can save enormous amounts of energy in the long-term. They’re more resilient, and they’ll pay for themselves within a few weeks. Of course, there’s also an environmental cost associated with manufacturing a new bulb – and thus it may be worth waiting for your old bulbs to fail before investing in a replacement.
If you’re burning gas in order to replace the heat that’s escaping through your windows, doors and walls, then you’re imposing a burden on the environment. Anything you can do to improve the insulation situation will therefore confer an environmental benefit. Often, the best results can be had by improving the situation in the loft.
3. Install a compost bin
Your kitchen will produce food waste, which can be put to use in the garden. Install a compost bin, and use the results to grow yourself some quality vegetables. You’ll be slashing your food miles in the process, too.
3. Heat Pumps
A ground-source heat pump is a device which draws energy up from deep in the ground, and uses it to help heat your house. Despite the name, the heat-pump can actually help to cool your property, too. Plus, you won’t have the visual upheaval that comes with solar panels. With that said, they’re tricky to install into existing builds, and their efficiency can vary according to the type of soil heat is being extracted from.
4. Photovoltaic Solar Panels
If you can claim a little bit of the energy that strikes your roof, then you’ll reduce the amount of fossil fuels that you’re indirectly causing to be burned. Over the course of decades, again, the investment in solar panels will pay for itself – and you’ll get the benefit of solar grants to sweeten the deal still further.
Water is essential to life, making it one of the most valuable resources on the planet. We drink it, use it to grow food and stay clean. However, water is of increasingly short supply and the Earth’s population only continues to expand. Many of the countries with the largest populations are also ones that use the most water. For instance, in the United States, the average person uses 110 gallons of water each day. Meanwhile, three-fourths of those living in Africa don’t have access to clean water.
To ensure we have enough water to survive — and share with those in need — the best approach is to conserve this resource and find sustainable ways of recycling it. Currently, conventional methods or water purification use about three percent of the world’s energy supply. This isn’t sustainable long-term and can have adverse effects on the environment.
Recently, however, major steps have been made to reduce both the collective water and carbon footprint. Now, there are multiple, sustainable ways to both save energy and reuse water using renewable energy.
1. Anaerobic Digestion
Anaerobic digestion — or AD — is the natural process in which microorganisms break down organic materials like industrial residuals, animal manure and sewage sludge. This process takes place in spaces where there is no oxygen, making it an ideal system for cleaning and reusing wastewater. This recycled water can provide nutrients for forest plantations and farmland alike.
For example, in Yucatan, Mexico, the successful implementation of AD systems has provided water to promote reforestation efforts. This system has also helped accelerate the search for a sustainable solution to water-sanitation issues in rural Latin American communities.
Additionally, anaerobic digestion also reduces adverse environmental impacts. As the system filters water, it creates two byproducts — biogas and sludge. The biogas can be used as energy to supply electricity or even fuel vehicles. And the sludge is used as fertilizers and bedding for livestock. In poor countries, like Peru, 14 percent of primary energy comes from biogas, providing heat for food preparation and electricity to homes that would not have access to it otherwise.
2. Vapor Compression Distillation
In this process, the vapor produced by evaporating water is compressed, increasing pressure and temperature. This vapor is then condensed to water for injection — highly purified water that can be used to make pharmaceutical-grade solutions.
The system only needs enough energy to start the first boil and a small amount to power the compressor. This energy can be easily supplied by a solar panel, producing roughly 30 liters of water an hour using no more energy than that of a handheld hairdryer.
3. Solar Distillation
Utilizing solar energy for water treatment may be one of the most sustainable solutions to the water crisis, without sacrificing the environment or non-renewable resources. Between 80 and 90 percent of all energy collected through commercial solar panels is wasted, shed into the atmosphere as heat. However, recent advancements in technology have allowed scientists to capture this heat and use it to generate clean, recycled water.
By integrating a solar PV panel-membrane distillation device behind solar panels, researchers were able to utilize heat to drive water distillation. This panel also increases solar to electricity efficiency. This device can even be used to desalinate seawater, providing a sustainable solution to generating freshwater from saltwater.
Environmental and Economic Benefits
Finding sustainable methods of recycling water is essential to reducing energy consumption and helping the planet, and all those dependent upon it, thrive. Using methods like anaerobic digestion and environmentally-friendly distillation processes can reduce toxic emissions and provide purified, recycled water to those who need it most.
Sustainable reuse of water can also benefit the economy. The financial costs of constructing and operating desalination and purification systems are often high compared to the above solutions. Furthermore, using recycled water that is of lower quality for agricultural and reforestation purposes saves money by reducing treatment requirements.
Growing interest in renewables is rapidly changing how energy projects are financed in America and around the world.
One of the biggest shifts has been an influx in outside money into the industry in the form of “green financing” — bonds, loans and other assets earmarked for renewable energy projects around the world.
The rise of the green financing market shows how investors are starting to take renewables more seriously — and it could signal a major transformation of the renewable energy market over the next few years.
Green Financing May Accelerate Renewable Energy Projects
Green financing is a catch-all term for investment in financial vehicles related to renewables and other green industries. Assets, bonds and funds related to renewable energy and other green investments make up the green financing market. In recent years, a robust green financing market has become widely viewed as essential to accelerating the development of new renewable energy technology projects.
Green finance is growing fast. In 2012, the sustainable debt market — including “green” and sustainable bonds and loans — was worth only around $10 billion, according to data from BloombergNEF. In 2018, just six years later, the market was worth nearly $250 billion.
Most of these gains came in the form of new green bonds (sometimes also called “climate bonds”), which are fixed-income investments designed to raise money for new renewable energy projects.
The growth of green financing represents a slow but noticeable divestment away from fossil fuels.
The pivot may also represent a change in how businesses are structured. The growing popularity of bonds as an investment vehicle may enable community co-ops rather than corporations to become a more viable business model for renewable energy providers. For example, the Westmill Solar Cooperative in the United Kingdom has raised more than £6 million ($7.94 million) through bonds offered to investors.
While coil, oil and natural gas are likely to remain a good investment in the short-term, the strength of the green financing market does seem like a signal that, over the next 10 to 20 years, non-renewables will become less and less tempting for investors compared to renewable and sustainable investments.
How Green Financing May Change Energy Around the World?
As the green finance market grows, regulators are beginning to codify what counts as a green investment.
These new definitions and regulations may determine which industries receive major funding and which are left out of the green financing boom.
Nuclear energy, for example, is generally not regarded as renewable energy, but is sometimes considered sustainable. Nuclear power plants generate waste, but they also produce zero emissions, unlike fossil fuel-fired power plants.
Natural gas is also not considered renewable or sustainable, as it is a fossil fuel and produces significant carbon emissions when burned for power. However, some proponents of the energy source argue that it should be considered sustainable, as it produces significantly less carbon dioxide than similar fossil fuels.
In 2019, EU regulators reached a deadlock over whether or not nuclear and natural gas power plants should count as sustainable investments. In a final compromise, EU lawmakers ruled that both nuclear and natural gas projects were neither included nor excluded in the definition of sustainable by default. Instead, projects would need to prove that they “do no harm” on a case-by-case basis.
Similar rulings and legal challenges could shape the future of energy as governments around the world grapple with the challenge of shifting away from fossil fuels.
A Coming Sustainable Energy Revolution
The rise of the green finance market may change what alternative energy looks like around the world. Legal debates over what should count as “renewable” or “sustainable” may affect which projects receive funding, while bonds and loans may make community cooperatives that provide renewable energy more practical.
As fossil fuels become less attractive to investors and the renewable energy market grows, green financing is likely to have major impacts on the future of renewables.
The first thing that comes to mind when you hear solar power is a solar panel placed on a rooftop for creating electricity for commercial or residential use. However, solar power has another important function – to mine and deliver water to improve productivity. This is especially applicable in sunny nations like Australia and most countries in Africa since its main industry is agriculture. Still, their productivity is suffering since their fields don’t get sufficient irrigation. Though, using solar pumps, they can double or even triple their profits. These economic gains can improve the lives of many farming communities.
Importance of Water in Agriculture
Our lives depend on clean water. The developed countries can sometimes take water for granted, but the evolving economies understand the significance of this commodity. A solar pump is an ecological option to get water for the crops and deliver drinkable, clean water.
The founder and CEO of the British-American company Ignite Power, Yariv Cohen, confirmed that solar pumps brought more efficiency, leading to bigger disposable income and more employment. Farmers can now grow three seasons per year instead of one. So, disposable income increased by 20% to 30%.
60% of the Sub-Saharan Africa population is employed in agriculture. Therefore, agriculture is accountable for 60% of economic output. This is less productive than the other regions in the world since only a part of the farmland gets constant irrigation – just 6% across Africa. Most farmlands go without irrigation, so most farmers in Africa rely only on rain for the larger lands, while they take care of the smaller areas with manual effort.
What is Solar-Powered Pumping System
The solar-powered pumping systems include a solar panel array, which fuels an electric motor. The motor, in turn, fuels the surface pump. The water is pumped from the stream or ground into a storage tank, utilized to water crops. If the farmland is irrigated consistently with solar pumps, the farmers will double the production compared to farmlands irrigated by rainwater or with manual effort.
About 600 million who live in Africa don’t have consistent electricity access. This is damaging the economic health of the continent. Everyone knows the ideal solution is to expand the electrical grid, but financial and geographical considerations prevent that. Ignite Power provides off-grid solutions to African countries in rural places like Nigeria, Mozambique, Rwanda, and Sierra Leone.
Cohen explains how solar pumps allow the farmers to irrigate their lands by using the sun. They first connect the homes, and then they utilize the same solar panels to water the fields. Using solar power, the pump enables a big area to be regularly irrigated. This improves the yield affordably.
Ignite Power has 1.1 million customers in Africa. So, there is room for enormous growth for his company and other providers of solar power in the continent. Cohen aims to reach 500 million houses.
They work with the bank and try to find the ideal solutions. They want to provide the best solution for the country with the help of the government. They can connect any payment providers or manufacturers to their system. They can connect all the suppliers, so many people could join.
The case of the two Rwandan women Grace Uwas (23) and Tharcille Tuyisenge (20) is admirable. They started working with Cohen’s company and bought solar systems for homes in Rwamagana, so people there have sustainable and safe electricity. Until now, they have installed twenty-five solar systems and more are coming!
Electricity is the quintessence for any country. The solar power is game changing for African evolving communities to get access. In this way, they won’t just keep their lights on, but their agricultural productivity will be improved.
