Four different guided technical tours of real scale plants operating in the production of energy from biomass and waste both by means of thermal and biological processes have been arranged for Thursday 15th November:
- Bio Treatment plant in Camposampiero (approx. 1hr from Venice), managed by Etra Spa
The plant of Camposanpiero, active since 2005, combines a biological wastewater and a solid waste (food waste, zootechnical wastewater, sewage sludge) treatment plant for the production of energy from renewable sources.
Food waste entering the plant undergoes specific pretreatments, which depend on the source of the waste, and it is subsequently digested anaerobically, in order to produce biogas and digested sludge.
Starting from the biogas produced, electric and thermal energy is generated through co-generators and boilers. In particular, the plant treats about 49.000 tons/year of waste, producing more than 3 millions kWh/year of electric energy and more than 5 millions kWh/year of thermal energy.
- Anaerobic Digestion plant in Bassano del Grappa (approx. 1hr 30mins from Venice), managed by Etra Spa
The treatment plant in Bassano, active since 2003, processes food waste and residual non-recyclable waste derived from separate collection in the Vicenza 5 basin, amounting to a total of about 70.000 tons/year.
In particular, food waste undergoes mechanical pretreatment and anaerobic digestion. The biogas produced within the three digesters is used for the production of electric energy, enabling the plant to self-sustain its energy consumption and sell excess energy generated.
The digested sludge then undergoes composting in order to allow the production of high quality compost.
The treatment line of non-recyclable waste consists of different physical-biological processes, aimed at the production of RDF/SRF and biostabilized material, used as landfill cover material.
- MSW Incineration plant in Padova (approx. 1hr from Venice), managed by Acegas Aps Spa
The thermal treatment plant in Padova is currently made up of three different incineration lines, which are now able to meet the needs for waste disposal of the Municipalities of the Padova 2 basin (180,000 t/y) and annually produce 78,4 GWh of electric energy.
The plant mainly treats residual municipal solid waste, non-hazardous special waste and hazardous medical waste.
Treatment of exhausted gases, as well as treatment of the wastewater generated by the different sections of the plant, is carried out in different stages, each of which is aimed at the removal of one or more pollutants.
The technologies and procedures adopted allowed the achievement of interesting results both in terms of the amount of waste burnt and energy produced, and of environmental performance.
- MSW Incineration plant in Brescia (approx. 2hrs from Venice), managed by Aprica Spa
The plant consists of three combustion units, one of which is dedicated entirely to biomass energy and built using the most advanced technologies. The waste to energy plant was conceived within the framework of an integrated waste and territorial management strategy and represents a valuable source of energy for the city of Brescia: indeed, the district heating network allows not only for the production of electric energy but also for the recovery of considerable quantities of thermal energy, by conveying the heat produced through the district heating network to the houses of the individual users.
In 2011 the Brescia waste to energy plant burned 796 thousand tons of residual municipal waste, special waste and biomass, obtaining 602 kWh of electricity and 747 kWh of heat (that is, almost 55% of the yearly thermal energy mains input in Brescia).
Buffet lunches will be offered to all delegates taking part in the tours.
Coaches will be provided by the Organizers. Expected departure and return times are 9am – 3pm for Camposampiero, Bassano and Padova, and 7am – 5pm for Brescia.
Places are limited and will be assigned on a first-come first-served basis; participants are therefore strongly advised to book their place as soon as possible and no later than Wednesday November 7th by email to firstname.lastname@example.org
