T/CGIA 004.1-2022 Guidelines for Green Preparation of Graphene Materials and Accounting of Greenhouse Gas Emissions: Part 1: Graphene Thin Films

Scope

Scope: This document reviews the typical process flow for the industrial preparation of graphene films, lists the consumption ranges of key factors such as raw materials and energy consumption, organizes the greenhouse gas emission accounting methods for typical processes, proposes green preparation pathways, recommends best practices for green preparation and potential technologies and carbon reduction suggestions, and provides a template reference for enterprise ledgers. This document provides guidelines for reduction, resource utilization, and reuse, as well as harmless treatment in the manufacturing process of graphene materials. This document is applicable to green park planning, green factory construction, green process evaluation, and green investment decision-making, etc. Main technical content: This standard defines the concept of "green preparation" from the aspects of material and energy reduction, resource utilization, reuse, and harmless treatment. By analyzing the energy and resource consumption during the typical preparation process of graphene films, it identifies the key factors affecting greening. Based on extensive research, literature, patents, reports, and production practice surveys, it proposes targeted best practices for green technologies and potential green technologies, providing reference and guidance for graphene enterprises. At the same time, referring to the national standard for greenhouse gas emission accounting for chemical enterprises and combining with the characteristics of graphene film preparation, it summarizes the greenhouse gas emission accounting methods during the preparation of graphene films and provides ledger suggestions, ultimately proposing carbon management and measures.
