The £4.6m capacity-building scheme, funded by Wrap, the Government's waste-reduction body, will offer consultancy support, marketing and fundraising training to charities and social enterprises working to encourage sustainable management of resources.
Wrap, which is wholly funded by the Department for the Environment, Food and Rural Affairs, will deliver the programme in partnership with a new community-interest company, REconomy, which was created in January to unite third sector waste and recycling networks.
"Waste is an unloved part of the third sector and it's a part that doesn't get the same resources as other sector groups," said Matthew Thomson, managing director of REconomy and chief executive of the London Community Recycling Network.
"The partnership will link all the sustainability organisations together better."
The initiative will be launched today in London at CRN's annual conference, People and Resources: Third Sector, First Choice.
Liz Goodwin, chief executive of Wrap, said she would tell delegates: "My experience is that the third sector includes many people who have the vibrancy, flexibility and skills for innovation that will be so critical."
Goodwin was also intending to praise the sector's "passionate commitment, vision and energy" in bringing the subject of reusing items to the forefront of public awareness.
