Use advice for data set Attention should be paid to the methodological aspects when using this LCA data. It is pertinent to note that this dataset is lacking domestic research literature, and therefore assumptions and values must be carefully scrutinized. The primary data should be recognized as representative of only specific cases in Southern China, and may not be widely applicable. Users must consider the density and usage of capping material which is stated as 2 kg/m2 with a density of 0.5 tonnes/m3. The absence of a defined start time for data collection necessitates reliance on the publication time of the source literature. The dataset must be used in accordance with ISO 14040 LCA standards, and all major raw materials and energy consumption should be included in the inventory data for a comprehensive assessment.
Technical purpose of product or process The described process refers to an environmental remediation technology specifically used for sediment restoration. The 'in-situ mulching' involves the capping of contaminated sediments with activated carbon (AC) to isolate contaminants and reduce their bioavailability. This process is typically used in aquatic environments such as lakes, rivers, and coastal areas to address pollution. The technical application of activated carbon mulching is aimed at improving water quality by mitigating the effects of contaminated sediments.
