San Diego completed the rollout of organic-waste recycling collection for customers served by the city.
The program asked households to place food scraps and food-soiled paper with yard trimmings in green bins. Diverting that material from landfills is intended to reduce methane emissions and create compost.
Delivering bins completed the logistical launch, not the behavior change. Low contamination, dependable collection and usable end products would determine the program's environmental result.
