Agricultural biomethane has also entered the public debate on energy transition in Molise, at a time when European and national policies are pushing decisively towards reducing emissions and more sustainable management of production chains.
In this context, the model developed by Retina is one of the most widely observed cases in central and southern Italy, especially in areas with a strong agricultural and livestock farming tradition.
The debate stems from a concrete issue: how to effectively manage livestock waste and agricultural by-products, avoiding environmental impacts and transforming a structural problem into a resource. In regions such as Molise, where livestock farming and agriculture are an integral part of the economic and social identity, the issue does not concern the introduction of new industrial activities, but the evolution of existing practices.
One of the most debated points is the distinction between urban waste treatment plants and agricultural biomethane plants. In the case of Retina, the operational scope is clearly defined: the plants use only biomass of agricultural and livestock origin, such as livestock waste and agri-food processing residues. They are not part of the urban waste cycle and do not treat organic waste from cities.
This separation is reinforced by a regulatory system that imposes stringent controls on the traceability of biomass. The sustainability of processes and access to incentives are subject to certification by the Energy Services Manager, who verifies compliance with environmental and production requirements. This mechanism makes transparency an essential condition for the operation of the plants.
The Retina model is based on a specific territorial principle: the plants are built where agriculture and animal husbandry are already present and generate waste to be managed. They do not involve the consumption of new land or changes in the agricultural use of the land. The aim is to offer farmers a stable and programmable solution for waste management, while reducing emissions and environmental pressures.
Through the anaerobic and aerobic digestion processes adopted by Retina, livestock waste is transformed into biomethane, which is fed into the national grid as a renewable source, and into organic fertilizers that are returned to the fields. This improves the quality of agricultural soils, limits nitrate dispersion, and reduces the use of synthetic chemical fertilizers.
The less visible but central aspect is the circular economy logic that characterizes the Retina project. Biomass comes from local farms and returns to the territory in the form of energy and fertilizers, creating a cycle that strengthens the autonomy of supply chains and reduces dependence on external inputs. This model has an impact not only on the environment but also on the economic organization of agricultural activities.
In the Molise debate, agricultural biomethane is often viewed with attention and caution. But the central issue remains the management of materials that already exist and which, in the absence of structured solutions, continue to represent a cost and an environmental risk. In this scenario, the Retina case offers a concrete example of how the energy transition can be integrated into traditional supply chains without distorting them.
For a region such as Molise, the evaluation of these projects depends on the ability to distinguish between perceptions and data. Agricultural biomethane, if included in a regulated and transparent framework, can become a tool for sustainable management and local development. This issue is set to remain at the center of debate in the coming months.
