Biorock

What Biorock does

Biorock, legally BIOROCK ROTOMADE SA, is a Luxembourg-headquartered manufacturer of non-electric biological wastewater treatment systems founded in 1988. The company's core technology combines a proprietary carrier material (BIOROCK Media) with a natural draft aeration system to deliver two-stage treatment (primary sedimentation plus bacterial bioreactor) without electricity, moving parts, or chemical inputs. The product portfolio spans capacities from 4 PE residential units (easyRock, Beasy 2000, MONOBLOCK) up to 10,000 PE municipal-scale systems (BIOROTOR RBC), with the ECOROCK and MULTIROCK lines covering small commercial and community applications up to 300 PE.

The company operates through a global certified dealer and installer network spanning more than 40 countries, supplemented by regional joint ventures: BIOROCK AFRICA (with Hummingbird SA, 2019), BIOROCK CHINA (with V&A, 2019), and BIOROCK (NZ) Ltd (2019). Manufacturing is performed on-site at the ROTOMADE SA rotomoulding facility in Ellange, Luxembourg, which houses 1,200 photovoltaic panels covering 50% of electricity needs. The revenue model combines one-time hardware sales (MONOBLOCK, ECOROCK, MULTIROCK, BIOROTOR units priced by PE capacity) with recurring installation, maintenance, and sludge-removal services delivered through certified partners.

Biorock holds an unusually deep stack of international certifications (EN 12566-3, AS/NZS 1546.1:2008, French Agrément 2010-026, German DIBt Zulassung C+N, KIWA, ISO 9001:2015, ISO 14001:2015, EcoVadis 2024), which functions as a significant regulatory moat in decentralized wastewater markets. The company is privately held under ROTOMADE SA with no disclosed funding rounds, no disclosed revenue, and headcount of 51-100 employees. Customer mix spans individual homeowners, hospitality operators (hotels, restaurants, campsites), commercial and institutional buyers, communities, and government/NGO projects in off-grid regions.

Core offering

BIOROCK designs, manufactures, and distributes non-electric wastewater treatment plants for residential, commercial, and community applications. Its proprietary BIOROCK Media serves as the carrier material for bacteria within bioreactors, combined with a natural draft aeration system, delivering electricity-free biological sewage treatment from individual homes (4-8 PE) up to large communities (10,000 PE).

Product overview

BIOROCK offers a complete range of non-electric wastewater treatment plants for residential, commercial, and community applications. The product portfolio includes easyRock (compact filter for 4-8 PE), Beasy 2000 (for chalets/garden areas), Monoblock (all-in-one residential system), Ecorock (two-stage treatment for up to 30 PE, scalable in parallel configurations), Multirock (high-capacity community systems up to 300 PE), and Biorotor (RBC technology for up to 10,000 PE). All systems utilize BIOROCK's proprietary media technology and operate without electricity using natural draft aeration. Systems can be configured as primary tank + bioreactor combinations, with retrofit options for existing septic tanks.

Broad incumbents

• Veolia Water Technologies: Global water and wastewater major that offers packaged and decentralized treatment solutions (alongside its core municipal/industrial business) through subsidiaries and regional brands. Veolia represents the broader incumbent benchmark for technology direction, regulatory engagement, and large-project competition that BIOROCK sometimes encounters.
• Kingspan Water & Energy (Klargester): Kingspan's water management division (including the Klargester brand) sells packaged wastewater treatment plants, septic tanks, and stormwater systems across the UK, Ireland, and broader EU. As a much larger listed incumbent, Kingspan offers overlapping decentralized treatment products but as part of a broader building solutions portfolio.
• Premier Tech (Ecoflo): Canadian-headquartered diversified manufacturer whose Ecoflo brand offers coconut-fiber-based decentralized wastewater treatment systems for residential applications across North America and selected international markets. Premier Tech is a much larger incumbent with a comparable decentralized-treatment value proposition.

Direct peers

• Tricel: Irish manufacturer of packaged wastewater treatment systems, water storage tanks, and composite products. Tricel's product range (including the Tricel Novo and Seta ranges) competes directly with BIOROCK in Ireland, the UK, and other European markets, particularly in the 4–50 PE segment.
• WPL Limited: UK-based manufacturer of packaged wastewater treatment plants for residential, commercial, and small community applications. WPL competes head-to-head with BIOROCK's MONOBLOCK, ECOROCK, and MULTIROCK lines in the UK and selected export markets, with comparable population-equivalent capacity ranges.
• Marsh Industries: UK manufacturer of domestic and commercial sewage treatment plants, septic tanks, and grease traps. Marsh serves residential, commercial, and community customers with packaged systems that overlap directly with BIOROCK's residential and small commercial product range.
• ClearFox: German manufacturer of containerized and packaged biological wastewater treatment systems for residential, commercial, and industrial applications. ClearFox competes with BIOROCK across the EU, particularly in small-to-medium community installations where biological treatment is specified.
• Graf: German manufacturer of plastic tanks, rainwater harvesting systems, and packaged wastewater treatment plants for residential and small commercial applications across Europe. Graf is one of the closest direct competitors to BIOROCK in decentralized wastewater treatment, with comparable product positioning and similar European certification footprint.
• Eloy Water: Belgian manufacturer of compact and decentralized wastewater treatment systems for residential and small community applications. Eloy Water's product range (including the Oxyfix and Helix systems) directly overlaps with BIOROCK's MONOBLOCK and ECOROCK lines, particularly in Belgium, France, and Benelux markets.

Emerging players

• BioKube: Danish developer of biological wastewater treatment systems for decentralized, small community, and humanitarian applications. BioKube has a narrower geographic footprint than BIOROCK but is comparable in technology orientation (biological treatment) and overlapping use cases including UNHCR-style humanitarian deployments.
