Blackburn with Darwen s red bag litter picking revolution NEARLY 2,000 volunteer litter-pickers have joined Blackburn with Darwen s red bag revolution since the scheme was launched. And council bosses have praised the hundreds of people who give up their spare time to help keep their borough tidy. Since the Keep Blackburn and Darwen Tidy initiatives began around three years ago, a total of 1,891 volunteers have signed up to be involved, with the respective Facebook groups continuing to grow by the day. Blackburn with Darwen Council has supplied 628 litter-picking kits to people since the start of lockdown, and during the Easter bank holiday alone, thousands of bags were collected across the borough.
