Digester gas can be generated by methane fermentation of biomass resources including wastes. There are great hopes that utilization of digester gas plays an important role in promoting reduction and recycling of organic wastes and creating a recycle-oriented society by producing renewable energy, as well as contributes to global warming prevention.

This time we have taken up an issue of Absorptive Storage of Digester Gas that has attracted attention in wastewater and water management fields recently.

As an effective use of digester gases, biomass power generation and biomass thermal utilization are being implemented. Absorptive storage of digester gas has been developed as a new technology for promoting more effective use of digester gases. This content describes the technology and the multiple facets of digester gas absorptive storage.
