Leachate is carefully collected and recirculated into the landfill cells to prevent contamination of land, groundwater and waterways. Some leachate is reabsorbed when passed back into landfill, but the rest filters through again, picking up more toxins with each pass.
When organic material such as food scraps and green waste is put in landfill, it is generally compacted down and covered. This removes the oxygen and causes it to break down in an anaerobic process. Eventually this releases methane, a greenhouse gas that is about 25 times more potent than carbon dioxide. Methane is also a flammable gas that can become dangerous if allowed to build up in concentration.
The implications for global warming and climate change are enormous. Composting your food scraps and green waste in a compost bin can eliminate many of these problems. And when it comes to moving the needle on greenhouse gas emissions, what really counts is what happens over the next 10 — 20 years. So how much methane is produced by a typical landfill site? A huge amount. In fact, enough to fuel a power station. For example, a landfill that serves a population of half a million, generates nearly 1.
When burned, methane produces carbon dioxide — just like oil and coal. Landfill meets a critical infrastructure need — to deal with the residual waste produced by businesses and households. This waste is expected to grow as the population increases, and with current consumer behaviours. Even with improved recycling rates, there is still general waste anything that cannot be recycled to be managed safely and effectively. At some level, most of us agree we should try to avoid, or at least reduce rubbish that we send to landfills.
The word landfill conjures up images of vast, foul smelling open tips, strewn with garbage, teeming with scavenger birds and flies. Let alone the pollution, and problems to wildlife and nature that come with landfills, which is becoming a more talked about subject.
Learn more on this here. Living a zero-waste lifestyle means you strive to use as little single-use plastic as possible, instead opting for sustainable and reusable alternatives. In short, it means you send as little as possible to landfills.
Replacing as much as possible with reusable products includes everything from food and drink packaging, to hygiene products, to clothing, either more sustainable or plastic free, which will help protect the environment, benefit communities and support a circular economy. At Unisan, we love helping workplaces dramatically increase their recycling rates and manage waste better, in order to send less waste to landfill and become more sustainable.
Setting up an effective recycling station can make all the difference. We believe this enables people to do the right thing and allow companies to demonstrate their commitment to sustainability and the environment.
Find out more here on how we help transform companies environmental commitments for the better, or call us on for expert advice on how your business can move further towards zero waste! We have a fantastic range of recycling and waste bins, whether for offices, schools, universities, reception areas, break out or canteen areas, or even for back of house, such as warehouses and distribution areas.

Conclusion In theory, providing there are no earthquakes, or underground methane gas explosions, landfill sites that are well constructed and managed may be able to contain toxic chemical and leachate byproducts for hundreds of years.
But the vast quantities of landfill gasses from landfills cannot be so contained. Before any methane is burned, landfills produce almost as much raw carbon dioxide as methane. And after taking into account burned off methane, a typical landfill site produces thousands of tonnes of carbon dioxide per month.
In striving to make our organisations and waste management more sustainable, we should be doing everything in our power to eliminate landfill waste. A To prepare the land before waste is deposited, several layers of linings are installed to seal up the base. Before beginning to deposit waste, this process has to be verified independently for quality assurance.
The process is: 1. A regulating layer is laid down to smooth out the surface. A layer of clay is then put down to provide an impermeable material to help prevent liquid from escaping.
The third layer is a plastic liner 4. Geotextile is then placed over the plastic. A fifth layer of gravel is then installed. Emissions from landfills pose a threat to the health of those who live and work around landfills. Large landfills, on average, decrease the value of the land adjacent to it by Smaller landfills depress land values less, with around a 2.
Minority and low-income areas are more likely to find themselves home to landfills and hazardous waste sites. These areas have fewer resources to oppose the placement of these facilities. This makes them an easier target for landfill placement than higher income areas. Every year the amount of waste that avoids the landfill increases due to recycling. Continuing to recycle will keep plastic and other materials out of the biosphere and put them to further use!
Avoid single-use plastics. Check out this article on single-use plastics and how to avoid them from the CU Zero Waste team here. Landfills lack the oxygen that compostable items need to fully decompose. By putting biodegradable items into the compost instead of the trash, huge amounts of waste can avoid the landfill. Landfills help to keep our communities clean, but they also pose serious threats to the health of our environment.
Waste such as televisions, computers and other electronic appliances contain a long list of hazardous substances, including mercury, arsenic, cadmium, PVC, solvents, acids and lead.

Leachate is the liquid formed when waste breaks down in the landfill and water filters through that waste.
This liquid is highly toxic and can pollute the land, ground water and water ways. When organic material such as food scraps and green waste is put in landfill, it is generally compacted down and covered. This removes the oxygen and causes it to break down in an anaerobic process.
Eventually this releases methane, a greenhouse gas that is 25 times more potent than carbon dioxide.
