Limeco

What Limeco does

Limeco is an intercommunal public-law utility institution (Interkommunale Anstalt) founded in 1959 and headquartered at Reservatstrasse 5, Dietikon, in the Canton of Zurich, Switzerland. It is collectively owned by eight municipalities (Trägergemeinden) — Dietikon, Geroldswil, Oberengstringen, Oetwil an der Limmat, Schlieren, Unterengstringen, Urdorf, and Weiningen — serving approximately 86,722 equivalent residents and a regional population of roughly 84,000 across the Limmattal. The organization operates an integrated infrastructure combining a Kehrichtverwertungsanlage (KVA) waste-to-energy plant, an Abwasserreinigungsanlage (ARA) wastewater treatment facility, Switzerland's first industrial Power-to-Gas installation, and a Regiowärme district heating network that spans 74.3 km and serves 576 connected buildings.

In 2025, Limeco incinerated 91,995 tonnes of waste, treated 12.5 million cubic meters of municipal wastewater, and delivered 172,797 MWh of district heating — a year-over-year volume increase of roughly 23%. Revenue is generated through a combination of municipal service fees (Betriebskostenbeiträge) for wastewater treatment, weight-based waste disposal charges at the on-site recycling center (with free disposal for many recyclables), district heating/cooling/steam tariffs (Regiowärme, Regiokälte, Regiodampf), and infrastructure planning services for municipalities on settlement drainage and sponge-city implementation. Net investments exceeded CHF 31 million in 2025, primarily directed at Regiowärme network expansion, the Limmattaler Energiezentrum (LEZ) generation project, and canal renovation works. The company recorded its ninth consecutive positive annual result, with CHF 9.6 million assigned to equity.

The company is governed by a Verwaltungsrat chaired by Stefano Kunz (departing end of April 2026) under CEO Patrik Feusi. Limeco's strategic agenda is anchored by the LEZ project — a multi-decade replacement of the KVA and ARA planned through 2034 with expansion scope to 2050, supported by a 2018 acquisition of the adjacent Coop-Areal (~64,000 m²). Strategic partnerships include Energie 360° AG for the Urdorf district heating network, Eawag for the Blue Nexus Lab climate-resilience research program, and operational partnerships such as the Firma Obrist e-truck charging arrangement. A new Anstaltsvertrag was approved by the control body in November 2025, formalizing the governance framework needed to execute this long-term capex pipeline.

Revenue model

1. Municipal Services & Waste Disposal Fees: Limeco generates revenue through municipal service fees (Betriebskostenbeiträge) for wastewater treatment services paid by the 8 Trägergemeinden, fees for waste incineration and disposal services charged per kilogram, and district heating (Regiowärme) sales to connected buildings. The company achieved CHF 9.6 million assigned to equity in 2025, with CHF 4.9 million from thermal waste processing and net investments of over CHF 31 million.
2. Regiowärme/Regiokälte Sales: Revenue from district heating (Regiowärme) and district cooling (Regiokälte) supplied to connected residential and commercial buildings. In 2025, 576 building connections delivered 172,797 MWh of district heating with heat revenues approximately CHF 3.6 million above previous year.
3. Municipal Planning Services: Planning and coordination services for municipalities in the areas of settlement drainage (Siedlungsentwässerung), Schwammstadt (sponge city) implementation, and infrastructure maintenance.

Core offering

Limeco operates an integrated municipal waste, wastewater, and energy utility for the Limmattal region of Switzerland, converting waste and sewage into CO2-neutral heat, electricity, and green gas. The company runs a KVA waste incineration plant, an ARA wastewater treatment facility, Switzerland's first industrial Power-to-Gas installation, and a 74.3 km Regiowärme district heating network serving 576 connected buildings. It also operates a public recycling center and provides guided educational tours.

Product overview

Limeco operates as an intercommunal infrastructure company providing integrated waste management, water treatment, and renewable energy services to the Limmattal region of Switzerland. The core product portfolio centers on three interconnected services: (1) Abfallentsorgung (Waste Disposal) including recycling center operations with free and fee-based waste processing; (2) Regiowärme (Regional Heat), a CO2-neutral district heating network supplying over 576 connected buildings with heat recovered from waste incineration and wastewater; and (3) Wassermanagement (Water Management) encompassing drainage planning and wastewater treatment. These services are powered by core technologies including the Kehrichtverwertungsanlage (KVA) waste-to-energy plant, the Abwasserreinigungsanlage (ARA) wastewater treatment facility, and Switzerland's first industrial Power-to-Gas installation. The Multi-Energy-Hub integrates these technologies into a unified renewable energy system. Limeco is also developing the Limmattaler Energiezentrum (LEZ), a major generation project to replace and modernize existing facilities by 2034. Educational discovery tours and the Blue Nexus Lab research collaboration with Eawag complement the operational portfolio.
