Pittsburg, CA- April 7th – Mt. Diablo Resource Recovery (MDRR), a leading environmental services provider serving more than 300,000 residents in the East San Francisco Bay Area, has been awarded the Solid Waste Environmental Excellence Performance (SWEEP) Platinum Certification—the highest level of recognition offered by the SWEEP Standard. This distinction places MDRR among the nation’s top performers in sustainable materials management and environmental stewardship.
“Achieving SWEEP Platinum is a testament to our team’s dedication to building a cleaner, more sustainable future for the communities we serve,” said Kish Rajan, CEO of Mt. Diablo Resource Recovery. “From innovative waste‑reduction strategies to investments in advanced recovery technologies, this certification reflects our commitment to environmental excellence and continuous improvement.”
The SWEEP Standard—the Solid Waste Environmental Excellence Performance framework—was created to transform the waste and recycling industry by establishing rigorous, data‑driven benchmarks for environmental performance, operational efficiency, social responsibility, and community impact. Modeled after the success of LEED in the building sector, SWEEP provides a comprehensive roadmap for municipalities and service providers committed to advancing a circular economy and reducing environmental harm. MDRR has been engaged with SWEEP since 2021, when it was selected as a pilot participant to help test and refine the national standard. During the pilot, MDRR demonstrated leadership in sustainable materials management, transparent data reporting, and community‑focused environmental programs.
To earn SWEEP Platinum, MDRR underwent a comprehensive evaluation across five performance categories:
- Policy & Planning – long‑term sustainability strategies and zero‑waste alignment
- Data Management – transparent, accurate reporting of materials and environmental metrics
- Collection Systems – efficient, safe, and environmentally responsible collection operations
- Recovery Programs – maximizing reuse, recycling, and organics diversion
- Disposal Practices – minimizing environmental impacts and supporting community well‑being
These categories reflect SWEEP’s mission to create “a world without waste where materials are valued and continually utilized for their highest and best purpose.
“MDRR’s achievement demonstrates what is possible when a service provider fully commits to sustainable materials management,” said Rob Watson, Founder and President at SWEEP. “Their leadership sets a powerful example for the industry and for communities nationwide.”
