What is 「Carbon Footprint」?

The earliest concept of carbon footprint originated from ecology footprint, in order to calculate how much of ecological area support to meet the requirement of consumption and service demands of daily life of each person。

Carbon footprint measured by CO2 quantification emission volume directly and indirectly of products whole life stage。

Life cycle: Take from nature resource or produced raw material to final treatment, in connect with the continuous and mutual linked process of the product system。(CNS 14040:2006-3.1)

The importance of「Carbon Footprint」

Enterprise internal assessment of greenhouse gas emission volume from products life cycle。

Calculation base on products greenhouse gas emission volume which can discover the carbon reduction potential to production process and resource cost waste, and choose proper replacement, operation or resource projects as information basis of reduction。

Production system closely linked, demands from supply chain increased daily。

Consumer or investor support and encourage enterprise to pay attention to related issues of greenhouse gas, investigation result of products carbon footprint can be taken as report content of enterprise social responsibility。

Consumer choose carbon tag products, expedites green consumption。

Let clients understand more about consumption choice create influence to global warming。


Category of 「Carbon Footprint」

  • Nation/city carbon footprint:whole nation/ city emission volume resulted from total material and energy consumed。
  • Enterprise carbon footprint:organization emission volume。
  • Service carbon footprint:exhibition activity service life cycle ex TPCA show 2010 convention activity carbon footprint。
  • Product carbon footprint:life cycle of commercial products。
  • Person carbon footprint:daily life consumption activity。

Requirement of supply chain in internation and each country

  • In 2007, (SCLC)developed by main cross-country enterprise , ask cross-country enterprise assist products supplier to provide greenhouse gas emission, reduction target , climate change strategy and enterprise risk assessment information. Dell ,whirlpool , P&G and Unilever are all take part in。
  • Global largest retailer (US Walmart) had sent its 100 thousand supplier to provide feasibility study in 2009 and ask supplier to give environment information include greenhouse gas emission etc., and let consumer purchase low-carbon products。
  • Many garment supplier (includes Nike, Adidas, Timberland and more than 30 members ) announced to organize 「Everlasting Garment association (SAC)」, intend to develop a green-tag plan to evaluate how environment had been affected by current marketing clothes and shoes, which includes water , energy, green-gas emission, etc。
  • Our domestic electronic manufacture begin their demands to ask supplier to provide green-house emission or products carbon footprint investigation。


Operation standard of carbon footprint

Current carbon footprint reference standard in our country。
  • BSI:PAS 2050:2011 specification for the assessment of the life cycle greenhouse gas emissions of goods and services。
  • EPA of Executive Yuan:footprint calculation reference of goods and services before ISO 14067 announced, to let person to follow how to calculate carbon footprint: Base on PAS 2050:2008. Coordinate with ISO 14067WD2 edition。
International carbon footprint reference standard。
  • Goods carbon footprint international standard ISO /TS14067 :2013 (Greenhouse gases — Carbon footprint of products — Requirements and guidelines for quantification and communication)。
  • Announced by “specification of technology” and reviewed every 3 years, which has to turn to international standard or canceled。
  • The content mainly as carbon footprint quantification and public communication。
Other international carbon footprint reference standard。
  • WRI/WBCSD:calculation and report of goods life cycle and enterprise value chain。
  • Japan:TS Q 0010。
  • Gernany :Product Carbon Footprint – Work on Methodology and Communication by the German Government。

Carbon emission during treatment process

  • Tradition or current organic waste treatment method is through digestion of microbe, and during its treatment process shall emit and release big volume of carbon content. In general it contains 50%-60% of material content。
  • Emitted to air in the form of CO2 on methane, the two gas had been reconized as main factor to result global warming. The greenhouse effect of methane is 300 times more than CO2。

Hidden cost of environment

  • • Through calculation of formula under -listed , We may know that each treatment of 1 ton organic waste by traditional method, Shall emit CO2 0.73 ton (1). Carbon right price international exchange market is about USD 25.00, if you treat organic waste by traditional method shall cost USD 20.00 more on environment pollution。
X40%(organic substance dry weight)
1 ton organic waste x 50%(carbon lose during compost process) =0.73 ton CO2
x W(molecular weight of CO2 / molecular weight of carbon ≒ 3.67)

Gain or lose from waste of organic substance

  • Whether through conventional compost, mechanical compost, fast fermentation, biogas, burry or direct disposal whose principle all apply「 the fermentation」of microbe to digest organic substance, and emit large volume of CO2 and methane。
  • Besides greenhouse effect resulted through gas emission, there shall be big volume lose of carbon inside the organic waste during treatment process, and make heavy lose of organic substance inside product and resulted the decrease of increment of organic substance content in soil。
Problem Counseling needs
Traditional or existing organic waste disposal is the use of microbial decomposition, so the process will lose a lot of carbon content, and emissions of carbon dioxide and methane, resulting in greenhouse effect and global warming。 Compared to traditional composting or high-speed fermentation, Ye Shan’s heap-free technology has the potential to reduce carbon efficiency. In order to understand greenhouse gas emissions and establish a good image of environmental protection, we hope that through the guidance of the construction of carbon footprint information。
Agricultural production is a complex system, farmers and organic waste producers stay in the traditional concept of handling, free technology and equipment promotion is not easy。 Through the carbon footprint to increase product sales value plus green image, the establishment of market segmentation, promote the use of free technology, and create a green low-carbon new business opportunities。
Domestic long-term organic waste as waste disposal, waste of renewable resources, ignoring the natural organic cycle chain。 Allow organic waste to return to natural resources for sustainable use, reduce waste disposal and increase soil。

Traditional Composting Technology

1.The traditional composting process is the use of long-term stacking, so that organic matter through the microbial 「decomposition」 release of carbon dioxide and methane, until it is completely decomposed, can be applied in the soil。

2.The so-called high-speed fermentation is also the use of microbial organisms will「decomposition」release of carbon dioxide, but not fully decomposed, so need to pile up after dozens of days to use。


Innovative technology — Composting-free technology

The composition of organic matter is mainly C (carbon), H (hydrogen), O (oxygen), N (nitrogen), S (sulfur), P (phosphorus), K (potassium), Ca (calcium) And other trace mineral elements。As the traditional composting or high-speed fermentation is the use of microbial 「decomposition」principle, so the release of carbon dioxide and methane during the fermentation process, resulting in a large number of organic carbon loss (about 50% to 60%)。

The use of enzymes is the「reaction」 principle of the enzyme, which quickly 「transforms」and「stabilizes」organic matter into fertilizers and can be used immediately for a short period of time, so there is no loss of carbon content, compared to conventional composting or High-speed fermentation, the free technology can achieve the goal of reducing carbon。


Analysis result of carbon footprint

In order to study the data acquired and proceed services carbon footprint analysis, the project apply Germany life cycle analysis assessment software GaBi4 compilation to proceed the analysis. The services carbon footprint assessment result reported by each functional unit「composting-free wastes treatment services」

Yes-Sun manufactured composting-free equipment and sell to users. The composting-free services unit is to calculate services material acquired stage. Services and ultimate dispose stage carbon emission volume. The wastes disposed during treatment process whose carbon emissions shall be include in services stage。

Greenhouse gas emissions of each stage of composting-free services life cycle:

  • Material stage CO2e 2.0735E 00 kgCO2e/ ton
  • Service stage CO2e 4.6232E 01 kgCO2e/ ton
  • Dispose stage CO2e 0.0000E 00 kgCO2e/ ton


Composting-free service distribution ratio in raw material, service stage carbon emission showed as follow, after analysis, each 1 ton wastes treatment volume-composting service carbon footprint 48.306 kgCO2e。


According to publication of EPA, waste incineration service produce carbon footprint 606 kgCO2e from garbage incinerator; and from south scientific industrial zone the number is 707 kgCO2e。

Referred wastes soil reservation journal Vol.45 No.1「Estimation of different kitchen waste treatment method whose greenhouse gas emission under IPCC method」, We find each ton of kitchen waste treatment whose GHG emission 33.759 kg CO2e。
