Quality control of fuels through CO2 monitoring and analysis

Fossil fuels are becoming scarcer and more expensive. Substitute and secondary fuels that can be obtained from waste from households, commerce and industry are therefore an increasingly interesting economic alternative for companies. The use of these fuels not only conserves resources, but also contributes to a reduction of CO2. The experts at WESSLING support companies at this point with analysis and advice on the quality control of the fuels used, and on CO2 monitoring.
