Republic’s solar-powered compost facility processing 100 tons daily, expected to double

The composting facility designed by SCS Engineers in collaboration with Sustainable Generation operates completely off the grid using solar energy.

In October, Republic Services' Otay Compost Facility at the Chula Vista, California, Otay Landfill opened for business. The compost facility helps communities in San Diego County meet the requirements of California's SB1383 law mandating the diversion of organic waste from landfills.

The composting facility designed by SCS Engineers in collaboration with Sustainable Generation operates completely off the grid using solar energy. It is the first fully solar-powered compost facility in the state and can process 100 tons of organics per day. There are plans to double the facility's capacity by year-end.

Republic Services hired SCS Engineers to design the Otay Compost Facility. The design uses renewable energy to run 100 percent of the composting operations at the site. The facility design includes using technologies to speed the maturation rates and reduce excessive odors. Blowers, oxygen and temperature sensors, and advanced compost cover technology produce a high-quality product.

As California collects and recycles organic materials from homes and businesses, local governments will use the products made from recycled organic material for compost and mulch. Recycling organic waste into compost creates a nutrient-rich soil amendment, preserving natural resources and reducing water consumption working within a circular economy. This California jurisdiction is ready for the SB1383 deadline on January 1, 2022.

Why invest money in an intelligent MRF (4.0)?

Traditionally, waste management companies have operated using a simple "management of waste" approach to operating a MRF. Throughput targets and continuous operation (minimal downtime) were the main driving forces. The industry has changed however, and the focus moving forward is now on optimizing system performance and reliability, in conjunction with increasing recycling rates and a drive for a "greener" and more sustainable tomorrow.

When considering the addition of, or upgrade to, an "intelligent" MRF, for municipalities or private operators, the main factors should always be the client's (operator) current requirements, and evolving market needs, which include throughput, reliability, output quality, and adaptability. Equally important is a full understanding of what is really expected from any proposed system. Having an engaged and focused mindset for the project with the client from the beginning, will impact and drive the entire design process. This then impacts the overall project result, through to the productive, efficient, ongoing operation of the facility itself.
