Protection against diffuse emissions |
Project: Thailand bases its economy on products coming from the agricultural sector (rice, palm oil, sugar, and so on) and for this reason there are many kinds of wastes classified as biomass such as rice husk (available in areas close to our cement plants), palm shell residues, coconut residues, sunflower residues, and others available in the country.
In 2005, after a learning and training programme, Italcementi Group’s Thai subsidiaries - tested rice husk in the precalciner system. The result was both positive from the operational point of view and cost-effective.
In early 2006 Takli plant installed the first new feeding system for rice husk, which was used to replace coal and lignite by around 5%. The same action was followed five months later by Pukrang plant. As a result, for the whole year 2006 the average biomass utilization rate of both companies grew from zero up to 2%, helping the Thai subsidiaries to comply with the Group’s objective of reducing CO2 emission levels.
In 2008, the three Thai plants (Cha-am, Pukrang and Takli) used around 130,000 tons of rice husks with a net saving of around 160,000 tons of CO2. Use of biomass in Thailand achieved an outstanding 9% substitution rate of the overall thermal energy demand in only two years.
