The retailer is expected to announce that it will launch recycling outlets at 347 of its stores, recycling household waste, plastics, clothes and other products.
It will also pledge to phase out PVC in packaging and cut the amount of waste that it sends to landfill.
Alison Austin, environment manager for Sainsbury, said: “Recycling is something we'd like to help make easier for our customers and by improving recycling facilities available, as well as selling food in more recyclable materials, we will be significantly contributing to achieving this.”
She added: “We recognise that many of our activities have some impact on the environment and our aim is to minimise these impacts through a programme of continuous improvement.”
Last week Tesco unveiled a ten-point community action plan which pledged to double customer recycling by 2008, to make carrier bags biodegradable from September and to use 25% fewer carrier bags by 2008.
