Attend Ambiental

What Attend Ambiental does

Attend Ambiental S.A. is a Brazilian industrial wastewater treatment company structured as a joint venture between Sabesp, one of the world's largest sanitation utilities, and Latte Saneamento, the largest environmental services company in Brazil. The company operates the Central de Tratamento de Efluentes (CTE) Barueri, a centralized off-site treatment facility located in the São Paulo metropolitan region with 36 covered discharge bays, capacity to receive up to 611 trucks per day, and combined throughput of 11,865 m³/day. At the core of the operation are four specialized treatment lines — Green (high-organic landfill leachate), Brown (high-solids septic and grease-trap waste), Yellow (inorganic heavy-metal effluents), and Gray (oil and grease emulsions) — supported by physical-chemical processes including dissolved air flotation, filter presses, sand classification, and biological treatment hand-off to Sabesp.

The company serves industrial enterprises across metalworking, galvanoplasty, chemical and petrochemical, metal finishing, sanitary landfill operations, and municipal sanitation. Revenue is generated primarily through a usage-based pricing model where clients are charged by the actual weight of effluent delivered, measured at INMETRO-certified truck scales at facility entry and exit. Supplementary revenue streams include CADRI regulatory certification advisory services routed through CETESB and laboratory characterization services performed under the company's in-house lab per Article 19-A of Decree 8.468/76. Customer servicing is handled through a dedicated consultant-driven sales motion and the Foconet web platform, which manages the full lifecycle of contracting, scheduling, documentation, certificate delivery, invoicing, and quality tracking.

The business model combines high capital intensity (physical plant, certified scales, 24/7 operations across multiple treatment lines) with a compliance-driven value proposition anchored by a stacked set of ISO certifications (14001, 37001, 45001, 37301) and LGPD alignment. The site has received architectural recognition at the London International Property Awards in the Public Service Architecture category, and the company has progressively expanded capacity since commencing operations on December 17, 2014 with two treatment lines, adding the Yellow and Gray lines in October 2018.
