TO A CO2 NEUTRAL INDUSTRIAL PARK: CASE STUDY

摘要

The industrial park of Herdersbrug (Brugge, Belgium) comprises 92 small and medium-sized companies, a waste-to energy incinerator, and a power plant (not included in the study) on its site. A park-wide inventory is made in order to study the “CO2-neutrality” of the park; CO2emissions in 2007, corresponding to the energy (electricity and fossil fuel) consumption and waste incineration, as well as the existing renewable energy (electricity and heat) generation, are recorded. A number of measures to further increase the generation of renewable energy (wind and solar energy, renewable energy from waste treatment) and thus avoid CO2 emissions, are projected and evaluated. Herdersbrug industrial park is CO2 neutral according to the definition of “CO2 neutrality of industrial parks” in Flanders; this definition considers only CO2 emissions due to electricity consumption, excluding CO2-emissions due to building heating and process heat. Existing and projected renewable electricity generation, gives even 66 kton more avoided CO2 than required for CO2 neutrality. From the CO2 emitted due to fossil fuel consumption and waste incineration, only 4.7 % is balanced by existing and projected measures. From the total CO2 emission (149 kton) due to energy consumption and waste incineration in the Herdersbrug industrial park in 2007, 62 % can be balanced by the CO2 avoided due to existing and projected renewable energy generated on the park; 45 % of the avoided CO2 is due to renewable energy generated from waste treatment (waste incineration and biomass fermentation). Renewable energy from waste incineration is a valuable and cost-effective method in order to achieve CO2 neutrality of an industrial park.
