California Waste Solutions expands recycling education to cut contamination

California Waste Solutions is expanding recycling education across Oakland and San Jose to help residents, property managers and businesses keep contamination out of recycling carts. The effort aims to improve material quality and reduce sorting problems that drive up costs and limit what can return to market.

Why it matters: - Contamination makes recycling more expensive and less effective by lowering material quality, slowing facility operations and sometimes keeping recyclables out of the market entirely. - California Waste Solutions is pairing education with sorting and property-manager support to reduce those losses in Oakland and San Jose, where the company serves more than 343,000 customers.

What happened: - California Waste Solutions, Inc. expanded its recycling education program across California to help residents better understand what belongs in recycling carts. - The program combines resident education, property-manager support and facility sorting to address contamination in Oakland and San Jose. - The company was founded in Oakland in 1992 by David Duong with eight used collection trucks. - California Waste Solutions received its first City of Oakland franchise in 1993 and has served the city continuously since. - California Waste Solutions now operates six Bay Area recycling facilities.

The details: - California Waste Solutions collects mixed recyclables and sorts them into paper, cardboard, plastics, metals and glass. - Facility teams recover material in grades that can move into further processing and manufacturing. - Food and liquids can soil recyclable paper and cardboard. - Plastic bags and film can clog sorting machinery and slow production or damage equipment. - Hoses and cords create similar entanglement problems. - Materials requiring special handling must stay out of the ordinary recycling stream. - Trained employees remove unwanted material and check recovered recyclables with sorting equipment. - Mechanics maintain the equipment, while supervisors oversee processing and customer service teams help residents with preparation and collection questions. - California Waste Solutions supports recycling education through school visits, neighborhood events and direct work with residents and property managers. - Outreach includes multilingual guides and sorting tools, plus explanations about unfamiliar packaging, special-handling items and what happens after collection. - Outreach events have included an Oakland Lakeshore street festival, the Oakland Housing Authority Summer Block Party and a session with a local Daisy Scout troop. - At apartment and condominium properties, shared collection areas require enough bin capacity, visible signs and consistent tenant information. - Oakland Recycles provides property managers with a toolkit and resident resources, and California Waste Solutions supports recycling guidance and communication with building operators.

Between the lines: - The company’s approach reflects a simple reality: recycling education is not separate from processing. The cleaner the incoming stream, the easier it is to produce material buyers will accept. - California Waste Solutions is using local events and building-level outreach to find the specific mistakes residents make, which can be more effective than broad public reminders. - San Jose and Oakland data show that contamination remains a measurable problem even as cities tighten feedback and education. - CalRecycle said China’s National Sword policy in 2018 forced recyclers to slow lines, add labor and buy equipment to produce cleaner material, underscoring why contamination control matters to the industry. - San Jose’s Biennial Recycling Characterization Study found single-family recycling contamination fell from 57% in 2022 to 41% in 2024. - San Jose’s February 2025 announcement said food- and liquid-contaminated paper and cardboard, plus plastics not accepted in the program, remained problems. - Oakland’s November 2025 audit randomly selected about 2% of trash, recycling and compost containers for inspection. - Oakland coordinated the audit with California Waste Solutions and other service providers, using “Oops!” tags for misplaced materials and “Good Job!” tags for correctly sorted containers.

What's next: - California Waste Solutions is likely to keep expanding education through schools, neighborhoods and property managers as contamination issues persist. - City audits and feedback tools in San Jose and Oakland should continue shaping where education is focused next. - The company will keep linking collection, sorting and customer education to improve the quality of recovered material for buyers.

The bottom line: - California Waste Solutions is betting that better local education will keep more bad material out of carts, improve recycling quality and make the system work more efficiently from collection to market.
