Bioreciclaje de Cádiz and Enagás Renovable Join Forces with Waga Energy to Produce Renewable Natural Gas in Spain 
  
 . The public-private consortium formed by Bioreciclaje de Cádiz (owned by Valoriza, GS Inima, and Consorcio de 
  Residuos de la Bahía de Cádiz) and Enagás Renovable has established a company whose objective is to develop a 
  renewable natural gas (RNG) generation project at the Medina Sidonia Landfill in the province of Cadiz in Andalusia 
  (South of Spain). To this end, they have signed an agreement with Waga Energy, which will install and operate its 
  technology for the project. 
  
 . The RNG upgrading unit will be commissioned by 2027 and will produce up to 273,000 MMBtu of energy per year - 
  enough to supply the annual energy consumption of approximately 16,000 Spanish households. 
  
 . The new facility will avoid the emission of around 21,000 metric tons equivalent of carbon dioxide (CO2) annually 
  [1], contributing to the region's carbon neutrality. 
Eybens (France), September 29, 2025 - Bioreciclaje de Cádiz is a public-private consortium formed by Valoriza Servicios 
Medioambientales, GS Inima, and the Consortium for Urban Waste Management in the Province of Cadiz, which manages the 
Miramundo Environmental Complex - Los Hardales. It has joined forces with Enagás Renovable, a leading company in the 
development of renewable gas projects, to develop a renewable natural gas (RNG) production project at the Medina 
Sidonia Controlled Landfill in the province of Cadiz in Andalusia (South of Spain). 
To this end, Bioreciclaje de Cádiz and Enagás Renovable have signed an agreement with Waga Energy (EPA: WAGA) - a 
specialist in the production of RNG from landfill gas - to build an RNG production facility in Medina Sidonia. The 
project will be developed at the Miramundo - Los Hardales environmental complex, which manages the public service of 
treatment and disposal of solid urban waste from 34 municipalities and belongs to the Consortium for Urban Waste 
Management in the Province of Cadiz. 
Under this agreement, Waga Energy will build a purification unit using its patented WAGABOX® technology to recover 
landfill gas and convert it into RNG. This marks Waga Energy's second project in Spain, following the first one near 
Barcelona. 
Waga Energy, the owner and operator of the WAGABOX® technology, will provide biogas upgrading services through May 2038 
and will deliver the RNG to Bioreciclaje de Cádiz and Enagás Renovable, who will be responsible for injecting it into 
the gas grid and managing its commercialization. 
The commissioning of this RNG plant in Cádiz is scheduled for 2027. It is designed to recover up to 1,400 scfm (2,400 
m³/h) of biogas and inject approximately 273,000 MMBtu (80 GWh) of RNG into the gas grid annually-equivalent to the 
energy consumption of 16,000 Spanish households or a fleet of 185 liquefied natural gas-powered heavy-duty vehicles. 
Last July, the Board of the Consortium for Urban Waste Management in the Province of Cadiz approved the launch of the 
project. This initiative supports carbon emissions reduction goals, one of the main measures of the Paris Agreement, by 
following a circular economy model that converts waste into valuable resources. Its implementation will prevent the 
emission of 21,000 metric tons of CO[2] equivalent per year by replacing fossil natural gas with renewable gas. 
The signing of the agreement for the development of the project has been made possible thanks to the collaboration 
between representatives of the companies Valoriza Servicios Medioambientales and GS Inima (which together with the 
Consortium for Waste Management in the Province of Cadiz form the company Bioreciclaje de Cádiz) and the CEO of Enagás 
Renovable, together with the CEO of Waga Energy Spain. 
Jose Antonio García Galdón, CEO of Waste Treatment by Valoriza: "Thanks to this new agreement with Waga Energy and 
Enagás Renovable, we continue to demonstrate our commitment to sustainable development by supporting a circular economy 
that turns waste into resources." 
Francisco de Los Santos, Director of GS Inima: "At GS Inima, we are proud to be part of a project that redefines waste 
management. By using cutting-edge technology, we are not only addressing the region's environmental challenges, but 
also creating a more sustainable future. We believe that this public-private partnership is the key to transforming 
waste into a valuable resource, promoting clean energy production and generating tangible benefits for the environment 
and our community." 
Antón Martínez, CEO of Enagás Renovable: "With the implementation of this new RNG production plant in collaboration 
with Bioreciclaje de Cádiz and Waga Energy, we reaffirm our commitment to a sustainable future by promoting innovation 
and efficient waste management." 
Baptiste Usquin, CEO of Waga Energy Spain: "We are excited about this new project in Spain with Bioreciclaje de Cádiz 
and Enagás Renovable, two leading companies in the environmental sector. Our WAGABOX® unit will allow us to transform 
landfill gas into a local, renewable, and circular energy source. By producing renewable natural gas-a key component of 
the energy transition-we are taking concrete action against climate change and helping to strengthen Andalusia's energy 
independence." 
Miramundo Environmental Complex 
The Miramundo Environmental Complex, managed by Bioreciclaje de Cádiz S.A., manages the public service of waste 
transfer, transport, treatment, and disposal for the municipalities of the provincial entity Consorcio para la Gestión 
de Residuos Urbanos de la Provincia de Cádiz (Consortium for Urban Waste Management in the Province of Cadiz), 
providing a social and environmental solution for its 618,000 inhabitants. 
The center processes around 340,000 tons of waste per year. Currently, biogas is partially recovered using two engines 
to produce electricity and heat. The new biomethane plant will enable this renewable gas to be fed into the grid, 
contributing to the decarbonization of the energy system. 
About 
Bioreciclaje de Cádiz 
The Miramundo - Los Hardales Environmental Complex in Medina Sidonia is managed by Bioreciclaje de Cádiz, S.A., which 
has held a 30-year concession since 2008 from the Provincial Consortium for Urban Waste Management in the Province of 
Cádiz to manage "the public service of transfer, transport, treatment, and disposal of waste from these municipalities 
and to provide social and environmental solutions for its 617,567 inhabitants." 
Bioreciclaje arose from a public-private agreement to undertake investments co-financed with European funds in the late 
1990s in the Miramundo - Los Hardales Environmental Complex. The public part was led by the aforementioned 
supramunicipal body, while the private part was led by a union of two companies in the public services and construction 
sector: Valoriza Servicios Medioambientales S.A., and GS Inima Environment S.A. 
The result of the agreement was the construction and commissioning of the Miramundo Waste Treatment and Composting 
Plant, created with the aim of leading the field in Southern Europe due to the technology used and its nominal 
capacity. 
Valoriza Servicios Medioambientales, S.A. 
Valoriza Servicios Medioambientales is a leading waste management company with a presence throughout the waste 
management value chain. With more than 40 years of experience, Valoriza provides essential waste collection and
