What Zerowaste Asia (ZA) does

Zerowaste Asia Pte Ltd (ZA), founded in 2013 and headquartered in Singapore's Cleantech Hub, is a high-tech environmental engineering and consulting firm that delivers patented physicochemical and thermal waste treatment solutions to government agencies, industrial manufacturers, environmental contractors, and construction companies across Asia. Its core technology stack comprises six registered patents — WCI (Wet Classification and Immobilization), CIP (Chemical Immobilization Process), SIL (Stabilization, Immobilization, and Lithification), MIL (Microwave Incineration and Lithification), WCS (Washing, Curing, and Stabilization), and SER (Selective Extraction and Recovery) — supported by patented specialty chemical reagents branded as ZA-TECH and ZA-H, and end-products branded as NEWSand (treated IBA for construction), ZALITE (lightweight aggregates), and ZAERO (horticultural media). The company addresses the full waste lifecycle from characterization and environmental impact assessment through design-build-operate delivery of treatment facilities and supply of reagents.

ZA generates revenue through three principal streams: (1) Design & Build services delivered under DB, DBOO, or PPP modes as managed services projects; (2) Reagent and system supply of proprietary ZA-TECH chemicals and treatment systems for client-implemented projects; and (3) Environmental Consulting for impact assessment, standards-setting, and policy advisory work. Pricing is project-specific and quote-based with no public price list. Go-to-market is consultative enterprise field sales targeting large-scale waste challenges, with Keppel Seghers acting as a strategic investor and channel partner since December 2019 to support international expansion. Customers span Singapore statutory boards (NEA, ESG, PUB, BCA, MND, JTC) and industrial accounts including Foxconn (wastewater treatment since 2017), CT Foodnex Mandai, and semiconductor manufacturers in Taiwan and Malaysia, with active projects in Singapore, China, Taiwan, and Malaysia and reference signals in Qatar, Maldives, Japan, and Hong Kong.

Core offering

Zerowaste Asia delivers turn-key environmental engineering solutions that transform hazardous and complex waste streams—including incineration bottom ash (IBA), incineration fly ash (IFA), sludge, contaminated soil, e-waste, and industrial wastewater—into reusable construction aggregates, horticultural media, and recovered metals. The company combines six patented physicochemical and thermal treatment technologies (WCI, CIP, SIL, MIL, WCS, SER) with proprietary ZA-TECH™ specialty chemicals, supplying branded products such as ZALITE™, ZAERO™, and NEWSand™, and executing projects under Design-Build, DBOO, or PPP commercial structures alongside environmental consulting services.

Product overview

Zerowaste Asia (ZA) is a high-tech environmental engineering and consulting firm founded in 2013, offering a comprehensive portfolio of waste treatment technologies and solutions. The company provides proprietary branded products including ZALITE™ (lightweight aggregates for construction), ZAERO™ (horticultural media), and NEWSand™ (IBA-derived construction material), alongside specialty chemical reagents under the ZA-TECH™ brand. ZA operates six core patented process technologies: WCI (incineration bottom ash treatment), CIP (incineration fly ash treatment), SIL (soft waste to aggregates), MIL (non-incinerable waste to lightweight aggregates), SER (metal recovery from e-waste/EV batteries), and WCS (IFA washing for utilization). The company delivers services across five verticals: Urban Mining, Remediation & Restoration, Hazardous Waste Treatment, Wastewater Treatment, and Environmental Consulting. ZA functions as a one-stop solutions provider offering consulting through design-build-operate services, serving government agencies, manufacturers, and environmental contractors primarily in Singapore and the Asia-Pacific region.

• Suez: International environmental services and water operator offering hazardous waste treatment, soil remediation and industrial wastewater chemistry comparable to ZA's ZA-TECH/SIL/CIP stack, particularly in the APAC markets ZA is expanding into.
• GFL Environmental: Diversified environmental services firm in solid and liquid waste, soil remediation and recycling; comparable in heavy-metal-impacted waste streams and growing hazardous-waste footprint that overlaps with ZA's IBA/IFA/SIL platforms.
• Tetra Tech: Global consulting and engineering firm with a leading Environmental, Health and Safety practice — comparable to ZA's environmental consulting leg (EIA, standards setting, solution design) and to the engineering backbone of its DBOO delivery.

Direct peers

• Clean Harbors: Largest North American hazardous waste treatment, disposal and industrial services company — closely comparable business model of field-based enterprise waste services, treatment chemistry and high-compliance disposal for industrial generators.
• Stericycle: Hazardous and regulated waste services provider to manufacturers and healthcare; comparable enterprise field-sales motion and focus on compliant disposal and recycling streams that ZA also serves through its NEA/PUB/JTC contracts.
• REMONDIS: One of the world's largest privately held recycling, service-water and hazardous-waste operators; comparable mix of proprietary process technology, DBOO project delivery and circular-economy product off-take.

Regional players
