London Assembly calls for deposits study to end plastic bottle blight of Thames
Mayor of London Sadiq Khan is being urged to explore the possibility of incentivising the recycling of plastic bottles after the London Assembly Environment Committee found that the troublesome products make up 10 per cent of all litter found in the River Thames.
The committee’s report into the environmental impacts of plastic water bottles, ‘Bottled Water’, was published today (13 April), and says that finding ways to improve the recycling rate of plastic bottles in the capital and providing alternative drinking water sources for Londoners is essential to preserving marine life and the natural environment of the city.
The report quotes research from Royal Holloway, University of London that found three quarters of the flounder swimming in the Thames had consumed plastic.
“Londoners need an alternative to buying bottles of water - this is a crucial part of the solution. Tap water needs to be more readily available. Secondly, we need to improve our recycling of plastic bottles. Currently, far too many end up in landfill or in the natural environment and London boroughs have some of the worst recycling rates in the whole of the UK.
“Electors heard Sadiq Khan pledge to be the 'greenest Mayor London has ever had’, now it’s time to fulfil that promise by addressing our thirst for plastic bottled water.”
Providing tap water as an alternative ‘essential’
According to the committee, which scrutinises the Mayor’s environmental strategies and looks at what additional measures could be taken to help improve the quality of life for Londoners, London consumes the greatest amount of plastic bottled water per capita than any other British region, and in the UK sales of plastic bottled water have more than quadrupled in the last two decades.
Plastic bottles make up 10 per cent of the litter found in the Thames, and in one day last year over 2,500 bottles were removed from the river by the Thames 21 organisation.
Of these bottles, just under 50 per cent are made up of water bottles, with cola bottles providing 12 per cent, sports drinks 10 per cent and a further 17 per cent being unidentifiable. For this reason, the committee says that action must be taken to provide alternative sources of water to Londoners.
Community water refill schemes, which encourage members of the public to fill up their water bottles for free at participating venues is seen by the committee as one localized and financially viable approach. Subsequently, the report urges Khan to investigate the possibility of installing more water refilling stations on the London Transport Network and look at how Business Improvement Districts could be used to trial potential solutions, as is currently being done with the Square Mile Challenge and coffee cups.
Deposit scheme among solutions to low plastic recycling in the capital
As well as the waste prevention measures suggested by the committee, the report urges the Mayor to explore the feasibility of a deposit return scheme (DRS) in London, with a view to approaching the government for London to be a trial site for a potential nationwide scheme.
The idea of a DRS, which adds a charge to, in this case, plastic bottles which is then repaid when the bottle is returned to a retailer for recycling, as a solution to plastic litter has taken off in the last year or so. Several high profile campaigns, including Sky’s Ocean Rescue and the Daily Mail, have backed the idea and waste management firm SUEZ called the measure a ‘win-win’ for the environment, manufacturers and ordinary households.
The plan for a UK DRS is not without its detractors, however, with several organisations saying that it would harm existing kerbside recycling services, negatively affect small retailers and potentially cause cross-border crime and fraud.
The committee’s report states that with London boroughs returning some of the lowest recycling rates in the country more must be done to ensure the recovery of plastic products. In addition to carrying out a feasibility study of a DRS scheme in London, the report recommends that Khan brings together plastics manufacturers, drinks producers, retailers, local authorities, waste collectors and recyclers to explore solutions to increase recycling.
Mayor supporting of better access to water, but favours national deposits solution
Responding to the report, a spokesperson for the Mayor of London said: “Sadiq is extremely supportive of initiatives to help boost access to tap water on the go, such as stores and restaurants providing free tap water, and, rather than just a London scheme, believes that Government needs to consider a national deposit-return scheme to encourage the re-use of plastic water bottles. The Mayor’s forthcoming Environment Strategy will include proposals aimed at reducing food and drink waste, including packaging, and increasing recycling rates.”
Previous analysis undertaken by City Hall suggests that a London-only DRS would be not be viable because of the commercial disadvantage it would cause London businesses, the infrastructure costs to a scheme based solely in the capital and the national supply chains of many manufacturers and retailers.
