SCHWENK Latvia cement plant in Brocēni is one of the modern industry examples in Europe where 80% of the used fuel is alternative. Its use reduces emissions of the manufacturing process and provides more environmentally friendly approach. 1500°C-2000°C temperature in the kiln prevents any waste and harmful emissions going into the environment and air.
Plant was launched for operation in 2010, and specifically built for the use of alternative fuel. All fuel is regularly and strictly controlled before it is used in the SCHWENK Latvija plant. Suppliers perform a full chemical analysis of materials in the independent, accredited laboratory and submit the test results to SCHWENK Latvija before deliveries of these materials. Additionally, tests are also performed in SCHWENK Latvija laboratory for each freight delivered to the Brocēni plant. Use of alternative fuel in the plant is supervised and controlled with the operating console and laboratory, the fuel is stored in modern storages, but ashes produced during the burning process are used in production of clinker.
Alternative fuel used in the plant is specially treated and prepared household and industrial waste (SRF), chipped tyres and neutralized polluted soil. After use of alternative fuel, zero amount of any kind of waste enters environment. Ashes formed during the fuel burning process bind with introduced raw materials in the kiln – limestone, sand, clay and form final product – clinker. It is the main ingredient of cement. Thus, fuel used impacts also the quality of final product.
