My Lords, I am grateful to the noble Lord, Lord Judd, for prompting further debate on the setting of targets for the landfilling of waste. Amendment 76 is designed to require the Secretary of State to set out a plan and timeframe, as soon as is practicable, for reducing and eventually eliminating the landfilling of organic waste. It would make it available for renewable energy generation and other appropriate uses, consistent with the waste hierarchy as defined in the Waste (England and Wales) Regulations 2011.
The Government support the minimisation of organic waste going into landfill and are sympathetic to the aims of this amendment. When we debated this matter in Committee, I outlined the considerable progress made in minimising organic waste entering landfill by the reduction of food waste and the increase in the number of anaerobic digesters generating energy from food waste. We very much agree with the points that the noble Lord made during that debate about the value of avoiding emissions of greenhouse gases from landfill. Preventing food waste is the most effective approach in carbon-saving terms: compared to landfilling, each tonne of food waste prevented means 4.2 tonnes of CO2-equivalent emissions are avoided.
We have worked very successfully with industry to reduce supply chain food and packaging waste by nearly 10% over the past three years, while the Waste and Resources Action Programme’s “Love Food Hate Waste” campaign helps consumers to make informed choices on reducing food waste. Household food waste is down by 13% since 2006, and we expect a 20% reduction to be achieved during the three phases of the Courtauld commitment that all the major supermarkets have signed up to. These results show that the voluntary approach can deliver real reductions
in waste while allowing businesses to be more efficient and competitive. We want to build on this work with businesses rather than impose targets or restrictions. When food waste cannot be avoided, anaerobic digestion is currently the best option that we have, because it produces renewable energy and a valuable fertiliser. Over the years, we have provided a range of support through WRAP for anaerobic digestion, including £11 million in grant funding.
The substantial increase in the number of anaerobic digesters generating energy from waste continues. We now have more than 100 megawatts of capacity for waste and, together with the long-standing use of anaerobic digestion in the sewage treatment sector, this gives us capacity to generate 1.5 terawatt hours annually. In the Government’s anaerobic digestion strategy to tackle barriers to anaerobic digestion, we estimated that there was a potential to generate 3 terawatt hours to 5 terawatt hours of electricity by 2020. With another 300 megawatts of capacity consented or being built, the industry is well on its way to delivering that potential.
Most of the actions in our anaerobic digestion strategy are now complete. The Government published a second progress report in August and it is now for industry to use the outputs to ensure that the barriers they identified are removed. I hope the noble Lord will be reassured that we can continue to reduce organic waste entering landfill by encouraging food waste prevention and supporting a growing anaerobic digestion industry without introducing further targets to those set out in the EU landfill directive. I also add that current evidence suggests that further statutory targets would have an impact on businesses and local authorities in compliance and monitoring, risking additional cost burdens on business. It is likely that these additional cost burdens faced by industry and local authorities would be passed on to the consumer, which means that consumers could risk facing higher costs if additional statutory landfill bans were introduced.
The noble Lord, Lord Grantchester, asked about reporting on a reduction of landfill. Landfill tax is the main form of reducing organic waste from landfill. Defra is encouraging food waste prevention and encouraging the use of anaerobic digestion; the Environment Agency monitors emissions under the industrial emissions directive. Under the permitting regulations, the Environment Agency also monitors the air quality.
We are mindful of the concerns expressed by the noble Lord, Lord Judd, around this sector, but I hope that I have been able to satisfy the noble Lord that the actions that we are taking and our encouragement of industries such as anaerobic digestive generators to make use of waste will help him to decide to withdraw his amendment.
