Ayudar a los agricultores a convertir los residuos en oportunidades.

We do not process food waste at our plants.  Anaerobic digesters process organic materials in the absence of oxygen to produce biogas and digestate. Our biogas plants are agri-centric and although feedstocks for an anaerobic digester can vary, the common ones from agricultural by-products and residues include: 

1. Animal Manure: Such as from cows, pigs, or poultry. It’s a rich source of organic matter and nutrients. 
2. Agricultural Residues: Such as crop residues, silage, or other plant-based materials left over from farming. 
3. Crops: Crops specifically grown for biogas production, such as maize or grass.

Our sites are professionally managed and the facilities must meet strict safety standards. Modern plants incorporate numerous design and operational safety features to mitigate risks, so  well-managed and maintained plants represent a low safety risk. Advanced monitoring systems, proper ventilation, explosion-proof equipment, and robust emergency procedures are essential to ensuring the safe operation of biogas plants (please see the list below), and regular training and adherence to safety standards further enhance safety.

Design Safety Features

• Gas-tight Digesters: Biogas digesters are built to be airtight, ensuring that gases produced during anaerobic digestion (such as methane, carbon dioxide, and hydrogen sulphide) are contained. Proper sealing prevents gas leakage, which is a critical factor in reducing the risk of explosions.
• Pressure Relief Valves: These are installed to release excess pressure that could build up inside the digester or gas storage systems. Controlled pressure management prevents over-pressurisation.
• Gas Detection and Monitoring Systems: Continuous monitoring systems are used to detect gas leaks, particularly methane and hydrogen sulphide.
• Gas Flaring: Excess gas can be safely burned off through flaring systems. In case of excess production or malfunction in storage, methane can be flared rather than allowed to build up.
• Explosion-Proof Electrical equipment: All electrical systems and machinery in hazardous areas are explosion-proof or ATEX rated. This means they are designed to prevent sparks that could ignite gas mixtures. This includes motors, switches, and lighting fixtures.
• Electrical Grounding: All metal parts of the plant are grounded to prevent static electricity from accumulating.
• Lightning Protection: Biogas plants are equipped with lightning protection systems to prevent lightning strikes from igniting methane. These systems direct lightning currents safely into the ground.
• Leak Inspections: Regular maintenance and leak inspections of the plant’s infrastructure are performed to detect and repair any gas leaks before they become hazardous.

No. We use odour control technology to significantly reduce odours and store our feedstock under negative pressure. Using digestate on fields in place of slurry provides water and air quality environmental benefits as it decreases the potential for organic pollution and also reduces odours from slurry spreading as the concentration of odour in the air is significantly lower when digestate is applied on the fields.

As part of the Environmental Impact Assessment Report noise level are assessed at the site. Noise monitoring and modelling are done to predict the noise levels during both construction and operational phases. Site specific noise mitigation measures may be recommended, if required within design phase to limit any noise so that there is no impact on surrounding receptors.  Noise mitigation features and measures will be implemented at the site as a standard practice to eliminate noise at the site.

Yes, operating an anaerobic digester can lead to a small increase in traffic levels around the facility, depending on several factors. Key factors that could contribute to increased traffic include:

1. Delivery of Feedstock: Materials such as agricultural by-products including manure, slurries and crop waste need to be transported to the digester.
2. Transportation of Digestate: After digestion, the leftover material, known as digestate, may need to be transported away from the site, for use as fertilizer.
3. Service and Maintenance: Additional vehicles may be required for the routine servicing, maintenance, and operation of the anaerobic digester facility.

The level of increased traffic will be mild, and a traffic management plan will be in place to ensure there is no traffic congestion or noise associated with the plant.

During the planning application through our Environmental Impact Assessment Report, we will access all the receptors in a locality concerning wildlife, rural and scenic areas of beauty, biodiversity and ecosystems in the locality. All our plants well be screened to blend into the natural surroundings of an area. Environmental protection practices will be utilised at all stages to preserve local ecosystems and biodiversity.

No, the plant will be self-contained and have no negative impact on surrounding local amenities. The Environmental Impact Assessment created for each planning application will look at all amenity concerns. The facility will be designed to blend into the natural surroundings of the area.

There are no major public health risks associated with the facilities. The material process is organic in nature and all operations are handled by strict public health and safety standards.
