bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non­governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
The Technical CommitteeThis document contains information on Biogas (ISO/TC 255) was established in
2011 in order to:
— provide liberalization and facilitation for international tradethe state of the art of biogas
systems;technology.
— contribute to international co-operation on technical regulations, standards and assessment procedures;
— curb discriminatory technical requirements as the main form of trade protectionism; and
— reduce and eliminate the technical barriers for international trade of biogas systems.
ISO/TC 255 intends to promote international technology exchange and to accelerate international application
of biogas (products) and equipment by developing and maintaining globally harmonized standards.
ISO/TC 255 Working Group 4 was established to prepare a standard that covers There are many and complex
links in the process of biogas plants construction, biogas production and biogas utilization. In addition,
the requirements for safe production and environmental protection have been continuously enhanced.
Safety accidents and environmental pollution risks are directly related to the survival and sustainable
development of the biogas industry.
The safety and environment guidelinesenvironmental information for biogas plants, biogas
transportation, and biogas use and biogas use introduced in this document are indispensable in the
processes of safe, environmental protection and stable operation of biogas plants.
This document is applicable for biogas plants, biogas transportation, and biogas use. The main purpose of this
document isBy introducing the safe and environment friendlyproduction and environmental protection
operation of the whole process of biogas systems.
This document for plants, the risk of safety and environment guidelines for biogas plants, biogas
transportation, and biogas use is applicable to:
— enhancing the safety of biogas plant construction, operation, and maintenance, preventing accidents and
environmental pollution and achieving the full benefits of biogas energy；
contributingplants can be reduced to reducea certain extent, and eliminate the environmental impacts
