Enevi

What Enevi does

Enevi, headquartered in Uvrier on the territory of Sion in the canton of Valais, Switzerland, is a public-interest association (association de droit public) operating a thermal waste recovery plant that has been in continuous operation since 1971 under a cantonal concession. The association serves 29 partner municipalities spanning the districts of Sierre, Sion, Hérens, and Conthey plus the communes of Salquenen, Varen, and Leytron, covering approximately 170,000 residents. Its core activity is the incineration of municipal solid waste, sewage sludge, and assorted industrial/commercial waste streams at a facility with capacity of ~9.5 tonnes/hour and ~230 tonnes/day, processing approximately 70,000 tonnes of waste annually. Enevi is governed by a Committee of Direction composed of eight elected representatives of its partner communes; it reinvests all revenues into infrastructure and operates without private equity or public shareholders.

The company's technical platform combines a modern waste-to-energy incinerator with flue gas treatment (DeNOx catalytic converter, electrostatic filters), an anaerobic digestion unit (GazEl SA, 51% owned, in Vétroz) for green and food waste, and a wood pellet facility (Valpellets SA, 50% owned) that consumes waste heat for drying. Energy recovery yields approximately 40,000 MWh of electricity per year from a new turbine commissioned in 2025, of which ~30% is self-consumed and the remainder fed into the grid under Switzerland's feed-in tariff regime, plus a district heating network supplying Sion (commissioned June 2022) targeting 50,000 MWh per year at term. Two intercommunal déchetteries (Uvrier and Chétroz) provide household and small-business recycling access, while the GastroVert food-waste collection system—deployed in 14 member communes via 156 collection Twins—processed 7,200 tonnes of material in 2024 and was spun out into a multi-plant joint subsidiary, GastroVert SA, in February 2025 alongside Satom SA and Saidef SA.

Enevi monetizes through a tiered transaction-fee model: per-tonne tipping fees (CHF 80 for wood, CHF 150 for street waste, CHF 180 for industrial waste, CHF 220 for confidential documents, CHF 300 for bulky/metal, CHF 600 for construction waste), a CHF 25 per-weighing tax introduced in September 2023, electricity sales under the Swiss RPC feed-in tariff, and district heating sales to partners such as Pôle Santé, Hospital du Valais, and OIKEN. Cumulative capital investment exceeds CHF 250 million since 1969, with recent projects including a CHF 20M district heating network and a CHF 10M turbine replacement. The company holds ISO 9001, 14001, and 45001 certifications, the Valais Excellence label (continuously since 2008), and trademarks for enevi® and GastroVert©.

Core offering

Enevi operates a thermal waste valorization plant in Uvrier, Valais (Switzerland) that incinerates approximately 70,000 tonnes of municipal solid waste and sewage sludge annually from 29 partner municipalities, generating about 40,000 MWh of electricity and supplying renewable thermal energy via a district heating network to the City of Sion. The company also manages two intercommunal recycling centers (déchetteries) and operates the GastroVert food waste collection system serving households and professional kitchens.

Product overview

Enevi is a public utility company based in Uvrier, Valais (Switzerland), formerly known as UTO (Usine pour le Traitement des Ordures du Valais central). The company operates as an integrated waste management and renewable energy platform. Its core offering is thermal waste recovery (incinerating ~70,000 tonnes annually from 29 communes serving ~170,000 residents), which generates electricity and thermal energy distributed via district heating to the City of Sion. Supporting this core are two intercommunal waste collection centers (Déchetteries d'Uvrier and de Chétroz), and the GastroVert food waste collection system (with Private and Pro variants) operated in partnership with SATOM SA. The company also holds stakes in Valpellets SA (wood pellets, 50%) and GazEl SA (methanization, 51%), which leverage enevi's waste heat for their operations. The portfolio forms a circular economy ecosystem where waste streams are fully valorized.

Broad incumbents

• ERZ (Entsorgung + Recycling Zürich): Municipal waste management utility of the City of Zurich operating one of the largest Swiss WtE plants (Josefstrasse, Hagenholz) plus déchetteries and district heating. Compares to enevi on the integrated waste-to-energy platform but operates at materially larger urban scale.
• Verbois (Services Industriels de Genève): Geneva's multi-utility (electricity, gas, water, waste) operating the Cheneviers WtE plant. Comparable as a Swiss public utility with combined electricity, district heating, and waste-processing activities, but with a broader service portfolio than enevi.
• MVV Energie: German municipal energy and waste group operating multiple WtE plants, district heating networks, and biomass facilities. Comparable business model (waste-to-energy + district heating + green-power sales) at larger European scale; useful benchmark for regulated WtE utility economics.

Direct peers

• KEBAG: Waste-to-energy incineration plant in Zuchwil (Solothurn) serving multiple municipalities, with electricity and district heating output. Closely comparable regional Swiss WtE utility with the same combination of tipping-fee, electricity, and heat revenues.
• Saidef SA: Thermal waste recovery facility serving part of Fribourg canton under the same cantonal concession model as enevi. Co-founding partner of GastroVert SA (Feb 2025); operates comparable waste-to-energy, district heating, and recycling center services.
• Limeco: Swiss waste-to-energy and wastewater operator in the Limmat valley (Dietikon). Operates KVA Limeco with electricity and district heating output from municipal waste — same integrated waste-valorization model as enevi at similar regional scale.
• SATOM SA: Thermal waste recovery plant in Martigny (Valais) operating the same UVTD (Usine de Valorisation Thermique des Déchets) model as enevi. Co-developer of the GastroVert food-waste collection system and co-founding partner of GastroVert SA; directly comparable in technology stack, customer base (municipal concessions), and revenue mix.
• OIKEN: District heating network developer and operator in Sion — direct partner of enevi for the heating network launched 2022. Comparable as the downstream thermal-distribution counterpart that monetizes enevi's recovered heat into residential and commercial customers.

Others

• ISDS Oulens SA: Landfill facility treating flue-gas washing residues from Swiss Romandie WtE plants, with a 0.05% enevi stake. Comparable as an adjacent waste-treatment ecosystem participant handling the ash/residue byproducts of enevi's incineration process.

Regional players

• Sogaval: Regional natural gas and biogas network operator in Valais that distributes GazEl SA's biomethane and enevi's thermal energy. Directly comparable as a downstream energy-distribution peer in the same Valais catchment.
