WtE Projects provide a number of key benefits to both the environment and to the local communities they service.
segnali gratis opzioni binarie Where waste does exist it is usually best to reuse it if possible, and if not, to recycle it. What can’t be recycled (the residual waste) can either go to energy recovery, or as a last resort, landfill. This general order of preference is known as the waste hierarchy.
Energy recovery is a favoured option, particularity where markets for recycled materials, such as compost, are poor.
There are many types of WtE technology, of which EcoEnergy Ventures favours Thermal solutions due to their ability to:
- Divert most waste from landfill;
- Provides a solution that is part of an overall Waste Management plan;
- Can increase recycling levels; and
- Is a scalable / modular solution that can grow with the Community
Some of the alternate WtE solutions and their associated issues are outlined below.
Non-Thermal Waste to Energy (aka. Chemically-enabled WtE): Can only break down feedstock that is biodegradable, giving it a limited applicability without removing the need for landfilling non-biodegradable waste. Non Thermal technologies also require a very high level of maintenance due to the requirement for a constant / chemically balanced environment.
Landfill gas (methane recovery): LFG (landfill gas) involves extracting the methane that naturally occurs in a landfill as part of the decomposition of waste. This methane is then flared on-site to power a generator to create electricity. Aside from the environmental impact of burning methane, leachate is left behind in the landfill- which can contaminate groundwater. This is solution still requires landfilling to occur (to create methane) and so is less of a solution than other Thermal options.

There is often concern that energy from waste discourages greater recycling. Throughout Europe and the US there are many examples where WtE plants coexist with high recycling levels, ultimately delivering lower levels of waste to landfill. Kerbside recycling efforts can be greatly enhanced by the sorting processes in a TWtE plant, or as in many sites in the US and Europe have shown, replaced entirely by sorting at the plant to produce a highly efficient recycling system.

Thermal treatment of waste diverts all waste from going to landfill. Unlike Non-Thermal solutions, organic separation and treatment is not required as organic and non-organic material is accepted into a Thermal system.
Landfill is the least sustainable option for our waste. Landfill is source of greenhouse gas emissions, pollutes the land and is expensive to maintain.
Landfill produces carbon dioxide (CO2) and methane (CH4) in roughly equal proportions. Both these gasses contribute to global warming, although methane is around 25 times as damaging as carbon dioxide.
Some of the impacts of landfilling:
• Landfills are slow to establish, taking up to 10 years, and costly with the cost of readiness peaking over the maximum income period.
• Landfill has a long ‘contaminating lifespan’, the routine aftercare and long-term financial liabilities continue for 15–30 years after a landfill site closes.
• The decomposition of waste in landfill takes 100–150 years.
• Landfill creates greenhouse gasses as it decomposes.
• There is limited land available for landfill, it relies on transport and the use of emissions is inefficient.
• Transporting waste out of a community to other landfill areas means millions of dollars are lost by that community over the lifetime of a landfill.
