Sludge from biodegradation processing
At Citizen Machinery's Karuizawa Headquarters, we use biodegradation processing that breaks down waste coating materials that contain organic materials to help us reduce the amount of waste that we produce. This process is executed using a system that creates no waste water, consisting of a wet coating booth that collects coating mist using a flow of water containing microbes along with processing drums equipped with devices that supply oxygen to the microbes as well as mixers. All that remains as waste are inorganic materials such as pigments. Compared to the conventional method of separating and collecting coatings using chemicals, we have reduced the volume of waste to roughly one third. Thanks to our microbial processing technique, the waste no longer retains the characteristic smell of organic solvents or the viscosity of coating sludge, bringing about other effects such as improving the work environment and reducing cleaning maintenance for equipment.
