A shocking 2 billion tons of waste are placed into
landfill sites around the world every year. It’s a massive global waste problem
and a practice that is not sustainable or environmentally friendly.
In this article, we’ll discuss why landfill
sites should be avoided at all costs and ways in which landfill sites can be
decommissioned by pursuing alternative methods for waste management.
At Gradeall, we manufacture practical
solutions that contribute to the global effort for pursuing recycling methods
and better waste management practices. We are committed to a sustainable future
that is supported by industry-leading equipment such as waste compactors,
and specialist waste machinery.
Landfill sites can be incredibly dangerous
and hazardous due to several factors that are primarily related to
environmental and health concerns.
Austria, Finland, Germany, and the
Netherlands are among the first countries that have implemented a landfill ban,
which indicates a promising start for eradicating this waste management
Many other countries are also showing
progress by banning certain waste such as end-of-road tyres from landfill sites,
as they have been shown to leach toxic chemicals and take hundreds of years to
Here are some reasons why landfills are
considered hazardous and dangerous:
When organic waste decomposes in a
landfill, it releases methane, which is a potent greenhouse gas that
contributes to climate change. Landfills also emit other volatile organic
compounds (VOCs) and hazardous air pollutants, which can have adverse effects
on the surrounding air quality and negatively impact human health.
Landfills generate leachate, which is a
liquid that forms as rainwater filters through the waste. Leachate contains
potentially harmful substances that can seep into the soil, this can cause
several negative side effects, including:
Landfill leachate can also pose risks to
human health if the food grown in contaminated soil is ingested. Depending on
the type and concentration of contaminants, potential health risks can include
respiratory problems, skin irritation, gastrointestinal issues, neurological
disorders, organ damage, and an increased risk of cancer.
Landfills contain a combination of waste
materials, including flammable items such as chemicals, plastics, tyres and
other combustible materials.
These conditions make landfills prone to
fires that can release toxic smoke and pollutants into the air. Landfill fires
are challenging to extinguish and can burn for long periods, posing risks to
nearby communities, emergency responders, and the environment.
Landfills emit strong odours due to the
decomposition of organic waste. These odours can be unpleasant for nearby
residents and affect their quality of life. Landfills can also attract vermin,
such as rats, mosquitoes and flies, which can lead to additional public health
concerns such as increased cases of malaria.
Landfills are visually unappealing and can
negatively impact the aesthetics of an area. The presence of a landfill in
proximity to residential or commercial areas can lower property values and
hinder economic development.
It’s important to note that modern landfill
management practices, regulations, and technologies aim to mitigate these
risks. However, the potential hazards associated with landfills underscore the
importance of waste reduction, recycling, and exploring alternative waste
Getting rid of landfills completely is a
complex and challenging task. However, there are several strategies and
practices that can help minimize reliance on landfills and reduce their
The most effective way to minimize landfill
waste is to reduce the amount of waste generated in the first place.
This can be achieved through initiatives
such as recycling, waste reduction programs, and encouraging sustainable
consumption practices. By maximizing recycling methods and diverting waste from
landfills, the overall volume of waste requiring disposal can be reduced.
At Gradeall, we have developed
industry-leading equipment such as the tire recycling range of machinery. This
provides a practical solution to recycling waste that otherwise would have
taken hundreds of years to decompose whilst posing environmental threats.
Organic waste, such as food scraps, and wood waste, make up a significant portion of
Implementing composting programs can divert
this organic waste from landfills and instead transform it into nutrient-rich
compost that can be used for gardening and agriculture. Composting reduces the
amount of waste sent to landfills while also providing a valuable resource for
Waste-to-energy facilities, such as
incineration plants, can help reduce the volume of waste going to landfills by
converting it into energy.
These facilities use controlled combustion
processes to generate heat and electricity from waste materials. One example is
tyre-derived fuel (TDF) which converts waste tyres as an
alternative fuel source for cement kilns.
While waste-to-energy facilities can be
controversial due to emissions and environmental concerns, modern technologies
aim to minimise this pollution and maximize energy recovery.
Landfills produce methane gas as organic
waste decomposes. Methane is a potent greenhouse gas contributing to climate
change. Landfill gas capture systems can collect and extract methane from
landfills, which can then be used as a renewable energy source or safely flared
off. By capturing methane, the environmental impact of landfills can be
Some regions have implemented landfill
diversion programs that encourage proper waste sorting and recycling. These
programs often involve separate collection streams for recyclables, organic
waste, hazardous materials, and other categories.
At Gradeall, we support this initiative
with waste management machinery that has been expertly designed to handle
specific types of waste, i.e.) the Large Glass Crusher, Can
Baler, MK2 Tyre Baler, etc. We aim to create
solutions that promote responsible and sustainable waste management practices.
It’s important to note that transitioning
away from landfill sites requires a comprehensive and integrated approach that
involves a combination of waste reduction, recycling and alternative waste
Government policies, legal regulations, public awareness and participation also play a significant role in achieving landfill reduction goals.
