How Composting Is Made

Disposed lumber and wood scraps are grinded into woodchips, and are mixed well. Our “Tokai Bio Bacteria” is then added to the woodchips. The bacteria and the raw materials are continuously mixed for 3 months, maintaining the moisture condition at a suitable level. This allows enough oxygen to interact with the bacteria and achieve optimal results.



Application Effects of Elements of Bio-Compost (EoBC), Tokai Bio’s fermentation material

  • Decomposes and matures non-biodegradable, wood-based organic matter in a short period of time
  • Eliminates foul odor with microbe that has deodorizing power
  • Kills off germs and weed seeds by thermophilic fermentation, and detoxifies toxic substance such as organic-based phenol
  • Bacteria used to manufacture organic bio-compost are active even in the high temperature zone during fermentation

  1. Unzen, Nagasaki Prefecture, Japan

Tokai Bio sent over 30 tons of “Bio-compost” to volcano-stricken areas of Unzen city where 10,000 trees were planted. Our “Bio-compost” proved to be very effective in restoring vegetation. Also, upon planting 60,000 tree seeds, Tokai Bio provided “Bio-mat,” a sack made out of tropical tree fiber which significantly improved the germination rate.


  1. Kagamigahara, Gifu Prefecture, Japan

A large-scale forest fire occurred in Kagamigahara city on April 5, 2002, affecting nearly 1,000 acres. It was one of the largest forest fires in the history of Gifu Prefecture. One month later, “Green Rebirth Project” was formed with the purpose of planting 10,000 trees to replace the damage caused by the fire. Tokai Bio donated 800 bags of 20kg “Bio-compost” to the project to help improve the soil, and the results were remarkable.


Application effects of Tokai Bio’s bio-compost to soil

  • Facilitates soil aggregation, and heightens soil’s water retention ability, permeability, and aeration property
  • Enhances soil’s fertilizer retention property, which allows for lasting supply of nutrients
  • Softens the shock of over-fertilization to vegetation
  • Various microbes coexisting within the soil prevents replant failure
  • Effective microorganisms comprised in organic bio-fertilizer suppress substantially increased nitrifying bacteria (produce nitrate-nitrogen) from chemical fertilizer and livestock manure. They also control pathogen development with opposing actions, and improves the microbial balance. By applying the organic bio-fertilizer, it increases soil’s fertilizer-retention and water retention qualities. It also reduces the amount of chemical fertilizer used, and prevents nitrate-nitrogen eluviation into groundwater.
