Fighting climate change must include a serious solution to rubbish landfills

Waste from food and other rubbish in landfills accounts for around 10 per cent of all global greenhouse gas emissions, according to the UN’s Environmental Programme.

                                                                                                  This methane gas leaking from landfills traps 81 times more heat in the atmosphere than CO2 over 20 years and about 28 times more over 100 years. Over the shorter period, its emissions are estimated to cause roughly one-third of the global heating driving the climate crisis.

This gas is released as materials slowly decompose after they are dumped in landfill. Food, paper and other natural materials are the main culprit because they cannot properly break down without oxygen.

Every year, there are huge leaks – known as "super-emitters”- from landfills that are captured and recorded on satellite imagery.

These include sites in emerging economies – but also surprisingly in Europe. We don’t usually associate such high levels of pollution with western Europe, but they are still commonplace in so many countries.

One solution here is to thermally treat and compact the waste to produce energy - and recover resources in the process – now commonly known as ‘Waste-to-Energy’. This reduces waste going to landfill and consequently methane emissions, as well as a host of other associated risks – such as soil and groundwater pollution.

Thermal treatment also allows for the recovery of metals, which cannot otherwise be recycled, and provides energy to local communities.

‘Waste-to-Energy’ is a highly regulated industry, having to meet strict environmental standards under the EU Industrial Emissions Directive.

 
The EU is currently consulting on its Emissions Trading System and its expansion to include Waste-to-Energy companies. This will mean that plants will need to purchase emissions permits for thermally treating waste – pushing up costs to the point which renders it uncompetitive and, in some cases, unviable." "Inclusion in this system would also fail to take account of the circularity coming with Waste-to-Energy - which sees metals and materials such as aggregate produced when it would be otherwise lost.

If the EU is serious about meeting its landfill reduction target, tackling climate change meaningfully, and improving people’s health, it must stop penalising the very solution that brings added benefits. Instead, it should accelerate efforts to end the landfilling of biogenic waste and increase recycling rates.
