Zero, a company based in the Californian Bay Area of San Francisco and surrounding areas, offers its customers a delivery service of fresh food. The Californians do not rely on biodegradable containers, but rather on reusable, more stable containers made of glass or silicone. These are cleaned by the consumers after use and picked up with the next delivery. The product range comprises almost 400 different products - from meat and other fresh produce to fruit and vegetables and snacks such as crisps and popcorn - and is constantly being expanded.
