Residential Food Waste Collection Access In The U.S.
Austin, TX, the newest program included in this year’s survey, just rolled out curbside service to 52,000 households at the beginning of October, and plans to expand to all households by 2020 (left). Anoka County, MN has two year-round drop-off locations at county yard trimmings sites. Each site has separate drop-off containers for food waste/soiled paper/compostable plastics, yard trimmings and tree waste (right).

Survey of residential food waste collection programs across the country from June to November 2017 ultimately identified 148 curbside collection and 67 drop-off programs.

Compost Use On Turf
The North Shore Country Club in Glenview, Illinois was an early adopter of using compost as a top dressing on golf courses. The Club utilizes an Ecolawn applicator to top dress its turf (loading the spreader (left) and application of an 85:15 sand-compost and biochar mix (right)).

Compost as a soil amendment prior to planting turf, and using it for maintenance as a top dressing product, are common applications on residential and commercial landscapes, ball fields and golf courses.
