ROCKFORD – A new worker-owned collective wants to help Rockford residents keep their food waste out of the landfill and instead turn it into nutrient-rich soil. Nettle Curbside Compost launched last week with its subscriber-based home pickup, which is offered weekly or biweekly. Customers fill their 4-gallon square bucket, seal the lid and leave it at their door for the company to oversee the decomposition into healthy soil.
