Experts from North America are flying in for the UK's first conference on zero waste.
The conference, at the University of Sussex, has been organised by the pressure group Zero Waste UK, which was inspired by campaigns to stop incinerators.
Communities from Nova Scotia to California have begun adopting initiatives to reduce what gets thrown away, prompted by fears about landfilling and incineration.
Among the speakers will be recyclers, engineers and academics who will talk about how the new zero-waste policies have evolved and how they are working.
Juli Johnson, of Zero Waste UK, said: "The response has been incredible. We have booked in representatives from town, district and county councils across the country.
"Interest has even been generated from other European countries and we have delegates coming from as far way as Slovenia and North Africa."
Defenders of the Ouse Valley and Estuary, formed to campaign to stop an incinerator in Newhaven, was among the dozen groups that helped to set up Zero Waste UK last year.
The conference takes place at the university on Saturday, February 16.
