The Renewables Energy Division of Garc SpA is specialized in design and construction of plants for the production of energy from renewables and alternatives sources.
The engineers and technicians of Garc manage and coordinate the design of renewable energy plants such as Solar and alternative energy sources like as Biomass and Biogas; analyzing customer needs, evaluating the potential of the site and environment to arrive at the definition of a feasibility study, also with the use of various technologies associated with it.
The Division also proposes the diagnosis, design and implementation of energy efficiency measures, for individuals, companies and public administrations: the analysis of the status of the plants, processes or wraps already present in order to identify problems and inefficiencies developed by such systems; planning and implementation of interventions and at the conclusion of the process, the analysis of the results obtained.
Significant is also the know-how acquired by Garc part of the recycling of municipal solid waste and industrial special waste, of post-consumer material; aimed to the next energy recovery from the same.
A source of energy is renewable when its exploitation takes place in a time comparable with that required for its regeneration. Unlike fossil and nuclear fuels, renewable sources – sun, wind, sea, earth’s heat – can be considered inexhaustible.
Biomass is defined as “the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries by including fisheries and aquaculture, as well as the biodegradable fraction of industrial and urban waste”.
Biogas is defined as “crops, vegetable waste and animal slurry subjected to anaerobic digestion or fermentation (ie in the absence of oxygen). After the cleaning treatment, this can be used as fuel, fuel for heating or cooling, and for the production of electricity”.
Energy Recovery from Waste
In 2009, per capita production of urban waste ranges between a minimum of 316 kg for the Czech Republic and Poland to a maximum of 833 kg in Denmark.
Italy, along with Austria, Germany, Spain, France and the United Kingdom has values between 500 and 600 kg, is in line with the European average.
In terms of waste management, while being increased in recent years, the trend for recycling and recovery, landfilling remains predominant.
Minimize the use of landfills has, in general, high levels of utilization of the heat treatments associated with good levels of energy recovery, mainly through the production of thermal energy intended for heating.
