§ Mr. Sayeed
To ask the Secretary of State for Environment, Food and Rural Affairs what assessment she has made of the proportion of waste sent to landfill which could be converted to biofuel through the an aerobic digestion process; and if she will make a statement. 
§ Mr. Meacher
We have not carried out such an assessment. Experience has shown that although anaerobic digestion is an appropriate treatment for a wide range of biodegradable wastes there are doubts about its commercial viability.
The Government support the development of anaerobic digestion through mechanisms such as eligibility for the Renewable Obligation Certificates. The waste management industry is reviewing the role of anaerobic digestion, along with other treatment options, to achieve the reduction in the biodegradable content of MSW sent to landfill as required by the Landfill Directive.
In these circumstances it is considered to be premature to make a realistic assessment of the quantities of wastes that will be treated by this option.
