Scope

GB/T 33756-2017 is the English-translated version of 基于项目的温室气体减排量评估技术规范 生产水泥熟料的原料替代项目.

GB/T 33756-2017 explains how to assess, project by project, the greenhouse gas emission reductions obtained by replacing raw materials in cement clinker production.

It covers what the assessment has to contain, the identification of the scenario and of the emission sources, the calculation of the reductions, the monitoring and the management of data quality, and the assessment report.

It defines the replacement materials it deals with: calcium carbide slag, the calcium hydroxide residue left once acetylene has been obtained by hydrolysis; coal gangue, the carbonaceous waste rock discharged in coal mining and washing; and fly ash, the powder collected from pulverised coal flue gas.

It applies to the ordinary Portland cement industry. It cites GB/T 176, GB/T 24851-2010, GB/T 32150-2015, GB/T 32151.8-2015, GB/T 33760-2017 and HJ 2519-2012. Issued on 12 May 2017, it has applied since 1 December 2017.
