Logging Tree Composting Technology: Making Way for Logs to Return to the Soil (December 2008)
Wood composting technology is an environmental technology to recycle logs and prunings generated from road maintenance, river improvement, and urban greening projects into compost instead of relying on incineration or landfill. Around 2008, the recycling of woody by-products began to take off in earnest, as the principles of the Basic Law for Establishing a Sound Material-Cycle Society took root at the municipal level and the Construction Recycling Law became more widely implemented. This technology produces stable compost through fermentation and decomposition by microorganisms after the logging trees are crushed and chipped. Improvements in fermentation accelerators and aerobic microbial materials have shortened the processing time and reduced odor, and the introduction of mobile equipment has made it possible to process compost close to the site. The compost generated is used for parks, slope greening, and agricultural land improvement, supporting a system of resource recy
cling in the region. The logging composting technology symbolized the transition to a recycling-oriented society that converts waste into resources and simultaneously reduces both environmental impact and disposal costs.
