Case Study A grocery store chain with stores across North America needed to reduce operating costs. Environmental expenses were high, but they could not hire in-house personnel to tackle the issue. Store management desired to be a good corporate citizen and also do right for the environment. Store management sought a way to connect with their local community and sustain a competitive edge. 16 THE PROBLEM THE SOLUTION Quest completed store assessments and calculated the chain's waste baseline. The team identified various waste streams that could be removed from the landfill, ran targeted pilots to calculate accurate savings on solid waste management cost, and measured employees' engagement with the program. Quest rolled out and managed the following landfill diversion programs: Food donation program Food waste recycling program Meat and seafood recycling program Cardboard and plastics recycling program Used cooking oil recycling program • Quest managed the remaining solid waste to maximize savings
