Sainsbury’s awards AD contract to Biffa

Thursday, February 4th, 2010

Sainsbury’s has signed a three-year contract with waste management firm Biffa to send food waste from 40 of its Midlands stores to the Birmingham-based firm’s anaerobic digestion facility in Leicestershire.

Supermarket giant Sainsbury’s has singled out anaerobic digestion (AD) as its preferred method of organic waste treatment and intends to send all its food waste to AD by 2012.

 Material collected under the agreement will be sent to Biffa’s 1.5MW Wanlip AD facility in Leicestershire, where it will be broken down to create biogas and used to generate electricity for the National Grid.

Since October 2005, Biffa has worked with Sainsbury’s to provide recycling and waste management services to around 600 stores. Under this agreement, Biffa has also overseen a waste oil recycling scheme, management of confidential paperwork and back-of-store residual waste collection, treatment and disposal.

“Securing this contract with Sainsbury’s for the management of food waste from their Midlands stores has been the culmination of 18 months hard work to optimise the performance of the Wanlip AD plant and then to secure the necessary authorisations to receive food waste direct” said Biffa’s engineering director, John Casey.

Biffa is currently increasing its foothold in the energy generation market and, in addition to increasing the capacity of the Wanlip facility, has also begun construction on a second AD facility in Cannock, Staffordshire. Biffa hopes to have the 80,000 tonnes-a-year capacity plant operational by autumn 2010 (see letsrecycle.com story).

Commenting on the arrangement with Biffa, Neil Sachdev, Sainsbury’s commercial director, said: “We are the industry leader in the use of anaerobic digestion and with this additional capacity provided by Biffa, we put ourselves even further ahead.”

“Respect for the environment is one of our key values, and as such, we will completely stop sending food waste to landfill within the next few weeks. We are desperate for greater anaerobic digestion capacity and would therefore like to see greater, clearer incentives for investment in this green technology.”

In January 2009, Sainsbury’s signed a “long-term” contract with PDM Group to handle its food waste in a move which was set to see the food waste recycling firm process material from all of Sainsbury’s 283 UK stores by the end of summer 2009 (see letsrecycle.com story).

The company explained that the deal with Biffa did not infringe on its existing arrangements with PDM, as Sainsbury’s was simply committed to using AD wherever was geographically practical.

A spokesman told letsrecycle.com: “PDM do food waste recycling for us via the process of fluid bed combustion. AD is our preferred method of disposal, so in areas where AD is available and within a practical distance of a depot, we will use that.”

Gloucester family cuts waste to one rubbish bag a year

Thursday, January 28th, 2010

When it comes to household recycling, one family in Gloucester take some beating. They have cut the waste they produce to just one bag a year.

The Strauss family dustbin is unremarkable in many ways. Admittedly it is metal, a rarity in the age of the plastic wheelie-bin, but it is dented, dusty and underused.

 

Where many families put their bin out once a week or once a fortnight, the Strauss family put theirs out just once a year.

Richard, 52, his wife Rachelle, 37, and eight-year-old Verona recycle everything they can at their home in Longhope in the Forest of Dean.

‘Careful not frugal’

“It’s about changing the way that you shop initially so that you’re looking at the product and making sure that the packaging it comes in is not something that’s excessive or something that you know you can either compost or recycle afterwards,” Richard explains.

A family holiday during the Boscastle floods in Cornwall prompted them to think about the impact the human race has on the environment, and has led to a change in their habits.

They insist they live a very normal life, they are not frugal – just careful.

I went with them to their local shops and Kevin’s Butchers in nearby Mitcheldean. I noticed many shoppers in the street with re-usable bags, but the Strauss family go one better – even taking their own containers along.

“When you buy meat and vegetables from your local store you can buy exactly the amount you want. No food waste, so it’s cheaper,” Rachelle says.

The butcher, Kevin Brown, is impressed. “They’ve opened up our eyes really to what we do waste. They’re a bit of an inspiration,” he says.

“Over the last 12 months I’ve seen a heck of an increase in people bringing their own bags in. I used to offer everyone a carrier bag and everyone used to take one. But not anymore.”

SECRETS OF EXTREME RECYCLING
Pick packaging that can be composted or recycled
Take containers into shops to carry loose products home
Compost paper and cardboard and either compost or use a wormery for vegetable peelings, fruit cores and crumbs
Sort bottles, cans and most plastics for kerbside collection or take to recycling depots
Reuse wire and plastic ties found in packaging to support plants in the garden

After carefully selecting food with minimal packaging the next step is to deal with the rubbish after the food has been eaten.

Where many of us find our kitchen bin – under the sink – Richard and Rachelle keep their tea towels.

“It makes us think about exactly what we’re throwing away,” Richard advises.

Vegetable peelings, fruit cores and crumbs go either into the compost or wormery. Tissues, paper and cardboard are also composted.

Bottles, cans, and most plastics are sorted either for kerbside collection or taken to recycling depots in the Forest of Dean.

I wondered about Christmas, and especially those little wire and plastic ties that most children’s toys seem to be plastered in these days.

“I use them to tie up my tomato plants,” Rachelle says. She seems to have a use for everything.

All that is left are crisp packets and some plastics. Once squashed, a year’s worth fits almost perfectly into their old metal bin.

The Strausses insist anyone can cut their waste – perhaps not to the extent they have but so much more is possible and every little step makes a difference.

So, just one bin for 2009 – what’s ahead in 2010? “Zero waste. No landfill rubbish, no bin,” Richard says.

Seeing the old dusty bin standing empty outside their cottage, you almost feel sorry for it, quite nostalgic. But Richard and Rachelle are not concerned about the past, they are determined to improve the future.

Axion runs “groundbreaking” carpet recycling trials

Monday, January 25th, 2010

Manchester-based Axion Consulting has undertaking “groundbreaking” trials to turn polypropylene carpets into plastic polymer that is suitable for reuse, in a move the firm claims could help stimulate the UK’s “fledgling carpet recycling industry”.

The project was initiated by carpet recycling trade association Carpet Recycling UK with the intention of finding recycling outlets for post-consumer carpets and possible end-markets for polypropylene (PP) from recovered sources.

Carpets which include manmade materials, such as nylon and polypropylene, account for almost two-thirds of the total number of carpets in the market.

However, carpet recycling is a nascent industry in the UK, with only 2% of the 500,000 tonnes of carpet waste produced each year currently being recycled and the remainder going to landfill or incineration.

Axion said tests at the plastics recycling facility its sister operation Axion Polymers runs in Salford found that plastic extracted from waste PP carpets in the form of an extruded polymer had the potential to be used in applications such as injection-moulded projects.

The London-based firm stressed that further testing was required to truly assess its sustainability and said that a large-scale trial would be required to demonstrate the commercial viability of the scheme.

Roger Morton, director of Axion, said: “We believe this is the first in-depth study of its kind in the UK and are very pleased with the positive results. Carpet recycling in the UK is currently limited with only a few companies involved and recycling processing in development stages.

“So this successful study shows exciting potential and promise for material recovery from a difficult and largely-ignored waste stream.”

Axion said that, while the economics of the recycling process “looked promising”, it was “critical to the viability of a commercial process” that PP carpets were separated from mixed polymer carpets. This is because mixed polymer carpets are not suitable for extrusion.

Carpet Recycling

Chief executive of Carpet Recycling UK, Kate Chappell, said: “This study shows there is great potential to reclaim valuable material from carpet waste and re-use it in new products in a variety of end markets. We are actively pursuing fresh sources of funding to take this exciting breakthrough to new levels.”

Carpet Recycling UK said it would now seek further research and was keen to pursue the commercial-scale trial of the PP carpet recycling process.

The trade body revealed in November 2009 that it intends to develop a National Action Plan to help stimulate a growth in the sector with a specific focus on broadloom carpets and improving collection of the material (see letsrecycle.com story).

Funding for the Axion trial was provided by Envirolink Northwest, which aims to aid the growth of energy and environmental technologies and services sector in the North-West of England.
