Dihua Sewage Treatment Plant Receives EPA’s Carbon Footprint Label

SSO receives Certificate for the Use of Product Carbon Footprint Label at award ceremony The Public Works Department Sewerage Systems Office (SSO)’s Dihua Sewage Treatment Plant received the Executive Yuan Environmental Protection Administration (EPA)’s Certificate for the Use of Product Carbon Footprint Label in August this year (2019). The Deputy Minister of EPA arrived at the plant on December 24 to award the certificate, allowing the largest level-2 sewage treatment plant in the country – processing half a million tons of sewage daily – to take the all-important first step in mitigating global warming and minimizing carbon emissions.

According to Deputy Minister of Environmental Protection Shen Chih-Hsiu, the EPA has launched the Green Mark system in 1992, and as of today approximately 4,600 products bear the label. Since the implementation of the Product Carbon Footprint Label in 2009, there are now 36 products (services) featuring the Carbon Footprint Label and 4 products (services) with the Carbon Footprint Reduction Label.

SSO Director Lee Chien-Hsien stated that the sewage treatment plant is a fundamental infrastructure of an advanced city. However, removing pollutants in the water also comes at a great cost of energy consumption, resulting in considerable carbon emissions. To remedy the situation, Dihua Sewage Treatment Plant has conducted a comprehensive audit of its sewage treatment-related carbon footprints, and the results have been verified by SGS Taiwan to obtain the EPA’s Carbon Footprint Label. By receiving such accreditation, Dihua Sewage Treatment Plant is the best embodiment of the Taipei City Government’s endeavors in promoting energy conservation and carbon reduction policy.

Kuo Shu-Chen, the owner of Forest Water Environmental – the company responsible for operating the Dihua Sewage Treatment Plant – commented excitedly that environmental protection has always been an important global agenda. Since engaging in the environmental protection industry, the company has vigorously improved the operating and maintenance quality of sewage treatment plants nationwide, and it has upheld the spirit of business conscience and given back to society.

According to carbon footprint audit statistics, Dihua Sewage Treatment Plant’s carbon footprint is 340g/m3 CO2e; in other words, for every cubic meter of sewage processed, Dihua Sewage Treatment Plant will emit 340g of CO2. The carbon emissions are mainly produced by the power needed throughout various stages of sewage treatment (as high as 87% of total carbon emissions). Therefore, the plant will strive to reduce power consumption in the future in a bid to decrease carbon emissions. In the preliminary stages, carbon reduction will be carried out via a three-pronged approach: treatment system, air conditioning system, and lighting system. This involves regulating the airflow of blowers, maintaining and configuring the central air conditioning systems, adjusting lighting, and installing energy-saving switches in order to meet the goal of decreasing carbon emissions by 3% before the next carbon footprint audit.
