Friends of the High Line will be taking their composting program to a new level using cutting-edge technology to compost in only 14 days. The Rocket composter technology allows for a continuous process of feeding it daily while constantly aerating the mass inside the vessel, producing high enough temperatures to kill pathogens. 

Friends of the High Line compost program began in 2010 as an effort to practice sustainable horticulture, reduce costs and create a high-quality product. The High Line gardens produce about 490 cubic yards of waste per year. Last year they were able to process 80% of that waste into 72 cubic yards of compost.   They are currently running two bins on a forced air system alongside their traditional bin system, which allows them to have more range and flexibility in their composting. The current bin system requires that the piles be manually turned in order to add water and expose the microbial community to oxygen. Andi Pettis, director of horticulture for Friends of the High Line, comments  “The rocket will help us optimize our composting initiative and allow us to create a streamlined, net zero, green waste system and achieve a more consistent final product that can be applied directly to the gardens or used to inoculate our compost tea.”  

The A900 Rocket composter model will be housed inside a container at the cross of 14th street and 11th av. There are hundreds of apartment buildings, businesses and people walking through the The High Line, which probably will never know that it is possible to compost at a commercial level in the middle of one of the largest cities in the world.
