How New York transforms millions of pounds of food waste to 'black Gold'

Watermelon rinds and pizza boxes with grease, as well as yard trimmings. These items would be destined for a landfill in many cities. In New York, these items are used to make something surprising valuable: "black-gold."

Jennifer McDonnell, the Deputy Commissioner of Solid Waste Management for the New York City Department of Sanitation said: "We are making this amazing compost that we can utilize throughout the city to improve soil health."

Staten Island's Compost Facility is managed by Denali Water Solutions. It has been processing landscaper waste for many years, but now it also processes residential organic waste. The facility receives 100-150 tons of organic waste on average, and up to 250 tons if there is a heavy leaf fall.

Composting starts as soon as the waste arrives. The piles can reach temperatures of over 100 degrees Fahrenheit (37.2degC), which is hot enough to kill pathogens, weed seeds and other weed seeds.

In the course of a few weeks, fungi and bacteria will break down the material. The end product is a dark, rich compost after curing and screening.

The city distributes free to residents, schools and community gardens.

McDonnell stated that "we've distributed, we believe, almost 6,000,000 pounds of compost this year to residents of New York City." Compost helps to improve soil health, control stormwater and maintain city green spaces.

According to the National Resources Defense Council, the majority of household waste is made up of food scraps and yard debris. They generate methane when they are disposed of in landfills.

Eric Goldstein is the New York City Environment Director for the Council.

Residents are required to separate yard waste, food scraps and food-soiled papers from their trash as part of the city's organics program. The enforcement of the law was suspended earlier this year but is expected to resume again in 2026.
