COMMENTARY:

What Happens to Your Food Scraps?

New York City began enforcing mandatory residential composting on April 1^st this year and our city now has the largest curbside organics collection program in the country. On average, NYC residents produce a staggering 12,000 tons of waste every day. But by separating compostable materials – food scraps, soiled compostable paper, and yard waste – we substantially reduce that amount by about one-third, or 4,000 tons. So if you ever find yourself bridling at the need to store your compost or dump it into a collection container, know that you’re having a significant and beneficial impact on reducing waste. You may even find, as we have, that removing both recyclables and compostables from your garbage means it takes a lot longer to fill up your garbage can. You’re making an important difference.

But what happens to all that organic waste? The City’s ambitious program to recycle food scraps from all our residential buildings utilizes both City agencies and private contractors: The NYC Department of Sanitation (DSNY) provides free curbside collection of compostable material, which is then transferred to processing stations operated by independent contractors. This material is then both directly composted and/or anaerobically digested to produce biogas.
