Centro Servizi Ambiente Impianti (CSAI), a subsidiary of the Italian multiutility company Iren, and Waga听Energy, a global expert in the production of Renewable Natural Gas (RNG) from landfills, have initiated a 10-year partnership to produce RNG at the Podere Rota Landfill in Terranuova Bracciolini, located in the province of Arezzo (Tuscany, Italy).
As part of this project, Waga Energy will purchase biogas produced by landfill waste from CSAI and upgrade it into RNG, a renewable substitute for fossil natural gas, thanks to its patented WABAGOX庐听technology. The RNG will be injected into the local gas transportation network and sold to an energy utility under a 10-year private purchase agreement. This innovative project combines CSAI鈥檚 know-how in waste treatment and recovery with Waga Energy鈥檚 unique expertise in producing RNG from landfills.
The Podere Rota Landfill has been closed since 2022 and is currently in post-operation phase. Its biogas production is currently recovered in the form of electricity by engines. The WAGABOX庐 unit will guarantee higher energy efficiency, supplying local and renewable energy that can be easily stored and transported via existing gas infrastructure, which substitutes fossil fuels for transportation, industry and heating.
The WAGABOX庐听unit at Terranuova Bracciolini will be commissioned in 2026, producing up to 98,950听MMBtu (29 GWh) of RNG per year, representing the annual consumption of approximately 3,400 households in Italy. The project will avoid the emissions of around 5,900 tons of CO2听eq. annually, by replacing fossil natural gas with renewable natural gas.
The project undertaken by CSAI and Waga Energy will optimize the management of the biogas produced by the Terranuova Bracciolini Landfill, with the goal of making a significant contribution to reducing greenhouse gas emissions and enhancing the local community鈥檚 energy independence. Andrea Baldini, CEO, Waga Energy Italia: 鈥淐SAI is the first waste manager in Italy to call upon the WAGABOX庐听technology which is already implemented in France, Spain, the United States and Canada. We are proud of the partnership between the public sector, an Italian corporation leading the energy transition, and a start-up committed to the fight against climate change. Renewable natural gas 鈥� made locally from the effective use of biogas produced by landfill waste 鈥� is a renewable and storable energy source that will serve to curb the use of fossil natural gas while restricting greenhouse gas emissions.鈥�
Mathieu Lefebvre, CEO, Waga Energy: 鈥淲ith our very first contract in Italy, we are pleased to initiate the rollout of the WAGABOX庐 solution in this country, paving the way to a highly promising market for Waga Energy. This partnership with CSAI is the concrete manifestation of a shared ambition to decarbonize the economy through renewable natural gas production, contributing to the fight against global warming.鈥�
