Start of Joint Testing with Leave a Nest to Verify Bamboo Powder Effectiveness

Jun. 20, 2019

Tokyo, June 20, 2019 — EarthTechnica Co., Ltd., a Kawasaki group company, announced today that it has commenced joint verification testing together with Leave a Nest Co., Ltd., a company with a wealth of knowledge in agriculture, to confirm the effectiveness of bamboo material (bamboo powder) processed using a   SHOKUSENKI MACHINE(For Defibration,Expanding,and Moistening

 

This equipment processes branches and twigs from trimming and other plant waste, swelling* the materials to change their properties and facilitate conversion to compost, fertilizer, livestock bedding material, and various other useful agricultural and livestock products. Bamboo can be processed via swelling to create bamboo powder, which is used as a soil conditioner in agricultural applications. Bamboo is known for its strong vitality and growth speeds, which is why abandoned or improperly controlled bamboo thickets often disturb surrounding plant life—a widespread problem throughout Japan. In response, demand is on the rise for countermeasures against damage caused by uncontrolled bamboo growth.

 

The joint verification tests between EarthTechnica and Leave a Nest are being conducted from May to July 2019 in Masuda City, Shimane Prefecture, using a plant fiber processing unit manufactured, supplied and installed by EarthTechnica (model SM-18-30CR, processing capacity of 1.6–2.4 tons/hour) to produce bamboo powder. Leave a Nest is analyzing growth and harvesting results for soil and agricultural produce (mesclun / baby greens) using this bamboo powder, and then compiling data on the effects of bamboo powder on production, thus verifying the effectiveness of bamboo powder as a soil conditioner in physical, chemical and biological terms.

 

EarthTechnica is not only taking part in these joint testing operations as a manufacturer of plant fiber processing equipment, but also working with Leave a Nest to utilize test data and verification results to develop new uses for bamboo powder. In this way, EarthTechnica hopes to make further contributions to society in the fields of agriculture, forestry and environmental management, while also cultivating new business models.

 

The companies plan to present their progress and interim results at the Hyper Interdisciplinary Conference Masuda Forum, which is scheduled for July 25 and will be held in Masuda City, Shimane Prefecture with Leave a Nest as host.

 

Swelling process: Compressing and kneading of plant-matter waste containing moisture, followed by release of compressive pressure to achieve a swelling action. The swelling process breaks raw materials into fibers, making them more susceptible to the effects of microorganisms. This greatly reduces fermentation times and improves water and fertilizer retention, thus facilitating conversion to compost, fodder and other resources for various applications.
