Research Project 

*developing some parts of projects


Livestock animal- and producer-friendly bedding material with antibacterial and deodorizing properties


Although wood chips are widely used for livestock bedding, price competition with "woody biomass"is becoming worldwide.

The use of bedding is a must from the point of view of AW.

We will utilize unused resources for research on bedding


New feed and feed additives with antioxidant properties never seen before

With prices of "feed" and "feed additives" skyrocketing, safe, secure, and effective feeds are urgently needed. 

Feed additives that are not only friendly to animals but also to the planet such as methane emission control and heat stress suppression, etc.


「greevy」 for compostable paper materials and biodegradable plastics 

Traditionally, despite being "biodegradable" plastic, it takes six months to a year or more to decompose them.
However, by using "greevy," paper components can be decomposed in about 1-3 day(s), and biodegradable plastic materials in about 3-10 days.


Rice husk biomass feedstock utilizing greevy decomposition speed

Rice husks are discharged 2 million tons per year in Japan, and it takes about 1-2 years to compost them, and to convert them into fuel, it is necessary to grind them into pellets.
By using greevy, rice husks are decomposed within about 48 hours for efficient composting and fuel conversion.
