Executive Councillor for Bins Reports Amount of Waste City Sends to Landfill has Fallen


The Black, Blue, and Green bins in use in Cambridge

Cllr Pit reports the amount of waste the city sends to landfill has decreased and that compostable material is being extracted from Black Bin waste.

At Cambridge City Council’s annual meeting on the 27th of May 2010 Cllr Ian Nimmo-Smith put the following oral question to the Executive Councillor for Environmental and Waste Services, Cllr Pitt:

What progress is the city making towards reducing the amount of domestic waste that is not recycled but goes to landfill.

Cllr Pitt responded to say the amount of waste from the city going to landfill had fallen last year despite an increase in number of households. He gave the credit for this decrease to householders who he said had made more efforts to reduce the amount of waste going into their black bins. Cllr Pitt said that moving to two weekly collections and the provision of a larger container for recyling (the blue bins) had contributed too as had the adding the ability to recycle tetrapack cartons and batteries.

The executive councillor rattled off a lot of figures including “70Kg” and “12%”; which he said he would submit to council officers as a table for inclusion in the minutes. Cllr Pitt made a point of asking for his answer specifically, and the answers to oral questions generally, to be minuted but both the Mayor and Chief Executive stayed silent and didn’t respond with any assurance this would be done.

Cllr Pitt also said the council was promoting: “waste prevention”, and said that a plant to “reclaim” black bin waste was being commissioned at the moment. He said that compostable material was already being extracted from black bin waste but at the moment – during the commissioning – it was still being landfilled but he hoped that would change in the near future.

Cllr Ian Nimmo-Smith, who earlier in the meeting had been elected Deputy Mayor, so was speaking from the dias wearing a gold medal on a blue ribbon round his neck, thanked Cllr Pitt for his answer and asked if the executive councillor agreed that the percentage of domestic waste going to landfill should be given less prominence than the absolute amounts.

Councillor Pitt agreed, and to point out the problem with the percentage statistic being taken alone – he noted, in an example he pre-emptively described as absurd, that if he went out to buy paper to put in his blue bin that would increase the percentage of his waste which was being recycled.

As there has been a case of compost even from Green bins ending up being contaminated in such a way that affected people’s ability to use it on their gardens I wonder what is to happen to the compost derived from the black bins which surely inevitably will be even less “clean”. If it’s not going to be used as compost but left to rot somewhere else – what’s the real difference between doing that and letting it rot in the landfill – other than it being avoiding landfill tax? Is this a scheme which only makes any sense at all due to an oddity of the tax system? One possible benefit is capturing methane being released during composting more efficiently than is possible in a landfill and generating energy from waste.

  1. An article on the Mechanical Biological Treatment (MBT) plant at Waterbeach states:

    The process is expected to reduce the volume of the waste by 25% through the material extraction and a further 25-30% through the composting process – leaving behind a compost-like output. Subject to accreditation from the Environment Agency, Donarbon hopes to use the material in land restoration or to grow energy crops.

    The Donarbon MBT website states:

    Due to the fact that the input is mixed waste, the material produced cannot be used by farmers or the public, but Donarbon hope to use the compost-like output of the MBT plant for quarry restoration, growing energy crops or as a fuel.

    One worrying possible consequence of this last statement is the potential implication that once land has been used to grow energy crops – using contaminated compost – it might be hard to revert that land to food production use.

    There is no mention of direct energy production or of methane capture during the composting process on either site.

  2. This waste business is extremely important – probably the one local move we can make towards a greener way of life. But if the percentage of recycling is the criterion ( as the new rules suggest) then throwing stuff away is being encouraged rather than the reverse.
    And there is no mention of the horrors of plastic so called recycling which is shipped off to China to do untold damage to the health of people there as it is rather uselessly processed.
    The new initiative to discourage bi monthly collections will make it even harder for Councils to reduce landfill but the most heinous move of the new Tory government is to abandon the Pay as you Throw plans .
    Anyone who was deluded enough to vote for the Lib Dems at the Election are now seeing what it is bringing, unimaginative, centralized diktats – as for Huppert promising to vote against Trident ( and then not doing so) and to abolish student fees , it has manifestly compromised his position as MP for Cambridge.
