通过沼气净化获得的生物甲烷是否可以根据 REACH 免于注册？

Is biomethane obtained by the purification of biogas exempted from registration under REACH?

是的，根据 REACH 附件 V 第 12 条，通过净化沼气获得的生物甲烷被视为属于注册豁免范围。此豁免并非指生物甲烷本身，而是指在无氧条件下通过生物分解有机物（例如农业废弃物、城市垃圾、污水）产生的沼气（主要由甲烷组成）。尽管如此，通过净化沼气去除不良成分而获得的生物甲烷仍被视为沼气，因此根据 REACH 附件 V 第 12 条可免于注册。对于由原始天然气加工而成的甲烷，适用 REACH 附件 V 第 7 条中的豁免。从化石以外的其他来源获得的甲烷不被视为天然气，因此不在本条目的涵盖范围内。

Yes, biomethane obtained by the purification of biogas is considered to be covered by the exemption from registration according to Annex V entry 12 to REACH. This exemption does not refer to biomethane as such, but to biogas (consisting mainly of methane) produced by the biological breakdown of organic matter (e.g. agricultural waste, municipal waste, sewage) in the absence of oxygen. Nevertheless, biomethane obtained by the purification of biogas to remove undesirable components is still considered as biogas and is, therefore, exempted from registration according to Annex V entry 12 to REACH. For methane processed from raw natural gas, the exemption in Annex V entry 7 to REACH applies. Methane obtained from other sources than fossils is not regarded as natural gas and is, therefore, not covered by this entry.
