ABSTRACT
Purpose of this Bachelor's Thesis was to study the carbon footprint of Suomen Lämpöpuu thermowood manufacturing process. Company is going to increase utilization of their own waste sawdust in the process, which means investments on renewable energy. Part of the oil is already replaced. Manufacturing process of thermowood is under development.
This research included the whole production chain from wood raw material growing in forest up to supply to customer. Also transportation and energy consumption were included.
Carbon dioxide emissions calculated were based on the PAS 2050:2011, which is commonly used standard specification for the assessment of the life cycle greenhouse gas emissions of goods and services. PAS 2050:2011 is very suitable for the companies, which evaluate carbon dioxide emission of products lifetime.
According to the results, major emissions originated from the fossil fuel combustion and transportation. Especially, combustion of oil could be even half of the total emissions. Share of Thermowood own process from total CO2-emissions was about 50 %, which originates almost entirely from heating of wood by combustion of oil. Replacing oil with renewable wood would lead to almost zero CO2-emission.
According to the calculations total CO2-emissions covering the whole chain was about 70 kg CO2/s-m3.
