In an industrial area near the port of Wilmington, Delaware, in the United States, thousands of tons of rotting food, yard waste and paper products into rich compost is used to help farmers to plant and the owners feed their bushes .
In addition to turn into fertilizer, the compound also discarded reduces the volume of waste in landfills, saves waste disposal fees, cuts methane emissions, generates carbon credits for businesses and conducts soil nutrients back to its originating source.
Highly valued by gardeners, compost is just born for large industrial scales. But there are already signs that it is here to stay: as the case of Organic Recycling Center of Wilmington, who claims to be the largest how to calibrate a scale of its kind on the east coast of the United States.
In the center, built in an area of about 110 thousand square meters, customers pay $ 50 a ton to dump their waste in the compost plant, less than the extra $ 61 per ton to dump waste in one of three landfills health of the state, said Scott Woods, chief executive of Peninsula Compost Group, which controls access. "We are offering optimum how to calibrate a scale conditions for composting yard."
The waste is sorted to eliminate heavy and non-degradable material, how to calibrate a scale and then transfer it to a dozen long heaps where the natural rotting process, aided by special aeration and rotated periodically converts them into compost in eight weeks.
The increased deposition rates charged in the United States and a growing public demand for a greener life style made of commercially viable compost, according to Nelson Widell, a partner at Peninsula. "You must be in an area where deposit rates are high enough," he said.
Wawa, a chain of convenience stores that provides approximately six tons of trash (mostly coffee) per month from its two pilot stores, is saving $ 300 per month, reducing their rates of deposition, said Judy Ward, executive -Boss of Advanced Enviro Systems, which helps Wawa and other companies to seek sustainability. Composting food waste Wawa boosted the recycling of 48% of the waste stream, according how to calibrate a scale to Ward.
She added that the financial benefits of composting can be reduced by the increase in transportation costs for the new center, or by investing in new containers for food poisoning. But, according to Woods, the Peninsula, while there is an increasing demand on business sustainability, the financial benefits of composting will support how to calibrate a scale the new center. "The economic model works because it is simple and effective," he said.
