Earthwell Refill in Kensington, San Diego, is a zero-waste refill shop at 4114 Adams Ave where customers bring empty containers and fill them by the ounce with non-toxic household and personal-care products. The store carries shampoos, conditioners, body wash, lotions, hand soaps, face wash, deodorant, sunscreen, toothpaste, laundry detergent, dish soap, and all-purpose cleaners from brands including Dr. Bronner's, Rustic Strength, Uncle Harry's, and Griffin Remedy. The 92116 shop sits at the Kensington sign behind Burger Lounge, at the eastern end of the Adams Avenue commercial corridor where Normal Heights transitions into the Kensington village district. In its eighth year of operation, Earthwell Refill is the longest-running refill shop in San Diego and has diverted more than 9,000 single-use containers from landfills and waterways in a single year. Customers who arrive without a container can grab a free donated bottle from the shop's reuse bin or purchase a glass jar on site, and pricing by the ounce means shoppers control the exact quantity they take home. The product line extends to reusable household goods — bamboo toothbrushes, compostable kitchen bags, dish scrubbies, and beeswax wraps — and the store hosts workshops on topics including kokedama (Japanese moss-ball planting) and seasonal sustainability events tied to Earth Day and Plastic Free July. Adams Avenue's concentration of sustainability-conscious businesses includes coffee roasters and farm-to-table grocers such as Dark Horse Coffee Roasters on the same Kensington stretch. The owners, who previously lived in Takoma Park, Maryland, modeled the refill concept on the European reduce-and-reuse ethos they observed while traveling abroad.
