Councils across the North-west are aiming to boost food and garden waste recycling during Compost Awareness Week from 6 May.
Residents of Greater Manchester who compost at home between 6 and 12 May have the chance to win a compost bin and £100 of garden centre vouchers.
There will also be events held at Debdale Eco Centre in Manchester, including beginners composting classes and family activities.
Meanwhile the Merseyside and Halton Waste Partnership is also holding a series of composting events will run throughout the region.
These include a compost giveaway in Knowlsey; information events in St Helens; and composting workshops in Wirral.
Carl Beer, chief executive of Merseyside Recycling and Waste Authority, said: “Most people don’t realise that up to 30% of their household bin is made up of organic waste, which can be turned into compost.
“Composting is an inexpensive, natural process that transforms your kitchen and garden waste into valuable and nutrient-rich food for your garden.”
