About: Linea Energia builds plants for exploiting energy from wood biomasses using the best technology available. Through LGH Rinnovabili (held 100%) and Franciacorta Rinnovabili (strategic holding 48%), Linea Energia has built and runs two biomass plants, in Cremona and Rodengo Saiano (Brescia), which are expected to produce around 14 GWh a year. These plants are also designed to be educational, places where anyone can learn about how wood waste is recovered and used to produce energy.
To make the entire operating cycle more effective, LGH has decidedly focused on the system of separate waste collection, favoring the recovery of materials and energy, reducing landfill disposal and water, air and soil pollution. The wood waste is given directly or through its own selection plant with sorting and volumetric reduction at the woody biomasses plant that converts it into thermal energy.
Energy produced by the waste-to-energy plant is added in the district heating network of the city of Cremona.

So, wood waste has a positive balance in terms of emissions. The presence of biomass plants avoids the polluting emissions produced by fossil plants currently in operation (fueled by coal, oil, etc). The systems are equipped with the most modern systems to reduce dust and are respectful of the restrictive limits imposed by legislation. The systems are constantly monitored in order to guarantee full compliance with national and regional regulations.

The plant has a potential of 1 MWelectric and provides 5.5 MW of thermal power in the main backbone of the city’s existing district heating network
• The production of energy from wood waste that otherwise should be landfilled at high economic and environmental costs
• Investments in innovative technologies for infrastructure and waste management systems
• The promotion and implementation of a satisfactory door-to-door separate collection of waste

• Using and promoting on the territory the solutions with the lowest environmental impact, with particular reference to air quality: developing high-efficiency district heating and cooling, integrated with the use of renewable sources and cogenerated heat/ energy recovery
