Biomass for another life

We alter organic waste into charcoal by our biomass carbonization technology.

Simply put, biomass carbonization plant is a waste recycling plant that can alter almost anything organic into charcoal (called biochar) through pyrolysis. Processable ingredients include sludge, human waste, chicken manure, scrap wood, agricultural residue, food waste and water hyacinth among others.

As biochar can work as a natural fertilizer, soil conditioner, fuel etc., Meiwa’s biomass carbonization technology provides solutions to waste management and agriculture, environment and/or energy at the same time.

Meiwa’s biomass carbonization plant is used both by private and public sectors. Click the link below to study selected examples.

Pursuing technology to realize a recycling-oriented society


Pursuing technology to realize a recycling-oriented society

We believe that technology should not be to destroy nature but should serve to make human society more natural and harmonious. Based on this philosophy, Meiwa Co., Ltd. aims to realize a more sustainable society by developing and disseminating numerous products.

For example, organic waste and unutilized biomass generated in a way of consumption and production. These are valuable resources if you change viewpoints, and can be returned to something useful for agriculture and industry by carbonization, fermentation and gasification.

We help you to recycle resources in your region by productive product / experience / technical knowledge in range from recycling by biomass carbonization equipment, biomass power generation equipment or methane fermentation equipment, etc. to environmental countermeasures such as dust collectors and wastewater treatment plants, production of charcoal fertilizer for primary industry and households, wood vinegar and compost base material.
