Technologies in waste

ZERO WASTE BEGINS WITH RESEARCH

As they say, one man’s trash is another man’s treasure.  Our team of engineers and sustainability experts are always searching for new uses for recovered resources. We work together with manufacturers to solve for industry-wide challenges.

Much of our work in waste processing begins with research. We take a three-pronged approach: our environmental engineering team seeks out emerging technologies throughout the world; we create pilot programs to challenge the status quo and find new answers; and we partner with other entities to research and identify new technologies for advanced materials processing.

Are you part of the emerging technology space or want find out about upcoming pilot programs? Contact us.

 


Some Technologies We Leverage

Optical Sorting

opticalsorting

Plastics need to be sorted into “like” plastics before baling, and optical sorting is one of the most efficient and remarkable ways to do so. The technology automatically sorts three common types of plastics with an infrared sensor: hard, clear, and colored. The sensor records the size, shape, structure, and position of the plastic on the sort line, and once identified, it hits the plastic with a strong puff of air, sending it into the correct plastics collection bin.

 


Negative Aerated Static Pile (ASP) Composting

ASP

Good compost needs added air and water. With a Negative ASP System, organic material sits on perforated pipes in open air, which pulls air down from the compost piles, making it easier to control moisture, oxygen, and microbial levels. The air that is pulled from the compost pile is processed through a bio-filter, which absorbs odors and volatile organic compounds.

Gas from Landfills Becomes Energy

LandfillGas

In 2013, Recology teamed up with G2 Energy to install a landfill gas-capture system at Recology Hay Road in Vacaville, CA. This system pulls the methane gas generated by the landfill and turns it into electricity to power homes and businesses nearby. The methane gas that’s pumped from the landfill is sent to an energy conversion facility operated by G2 Energy.

As a result, the methane captured from the landfill is now providing 1.6 megawatts of electricity – Enough to power up to 1,600 homes. This is equivalent to taking about 13,000 cars off the road, planting 14,500 acres of forest or otherwise offsetting consumption of approximately 7.6 million gallons of gasoline.
