In a recent statement he joined the debate on the suitability of AWC within high density city communities.
Livingstone said: Harrow Council is the only council to date in London to have introduced AWC. I am concerned that other boroughs will soon follow Harrows lead, despite the fact no research has been done as to its success in London.
I am not convinced that the research carried out in rural areas applies to the high rise, high-density buildings in some London boroughs. Some Harrow Councillors have raised concerns with my office that this policy has led to confusion with the public as to which days they could recycle.
"My suspicion is that alternate weekly collections are more about cutting costs than improving recycling rates. It is clear that the boroughs are introducing this without understanding the effects on environmental hygiene and the rodent population and the real test will come as we experience a long hot summer.
