RELANG Cjurasein LCA information Declared unit: In accordance with the requirements of PCR, the declared unit is 1 cubic meter (m3) of 12-mm thick solid surface sheet for a period of 10 years. To convert volume to mass, multiply the volume by the density of the substance. The conversion factor of volume to mass in the LCA study is 1770kg/m3. Reference service life: The warranty life of 10 years is used as the reference service life. Time representativeness: Data collection is in year of 2022, all used background datasets are valid for the entirety of 2022. Database(s) and LCA software used: Software:...

RELANG Cjurasein TECHNOLOGY * Production flow chart: Durasein® solid surface is produced through the following process: raw material - mixing - pouring -curing - cutting - grinding - cleaning - inspection - packaging. The raw materials are mainly aluminum hydroxide powder, PMMA resin, titanium dioxide paste and other pigments.The packaging materials are mainly corrugated paper and PET film. The energy consumption of the production process is low-voltage electricity (from China Southern Power Grid), the material consumption includes water for cleaning, and the emission includes volatile gases...

More information: Relevant assumptions in LCA: 1. Due to lack of transportation data for materials and products, the transportation data is based on background data, unified assumptions: road transportion uses freight lorry, Euro IV emission standards, 16-32 metric tons; freight ships are used for sea transport; rail transportation uses freight electric trains; 2. Due to the lack of transportation information at the end-of-life stage, it is assumed that the terminal waste transportation method is freight lorry (16-32 metric tons, Euro IV emission standard), and the transportation distance from...

RELANG Cjurasein TECHNOLOGY ^ W " * Cut-off rules: 1. This LCA has collected data for all unit inputs and outputs, including assumptions about missing data. 2. The proportion of the following raw materials is less than 1%, according to PCR requirements, this data can be discarded.

RELANG Cjurasein TECHNOLOGY ^ W " * Electricity mix: In this LCA study, Southern China grid electricity mix is used. The production of Durasein® Solid Surface takes place in Zhuhai, Guangdong province. The GWP result of low-voltage electricity in China Southern Power Grid is 0.428kg CO2 eq/kWh. The data comes from one-Metric (1mi1) local database in China.

RELANG Cjurasein TECHNOLOGY ^ W " * Sensitivity analysis: To analyze the robustness of the result from various assumptions in the LCA study, including waste transportation distance and waste landfill rate, a sensitivity is necessary to be carried. The sensitivity analysis results showed that when the distance of waste transportation increased to twice (200km), the change rates of ODP and GWP-luluc were 3.50% and 2.58%, and the change rates of other environmental impact indicators were lower than 2%. When the distance of waste transportation increased to 4 times (400km), the change rates of ODP...
