For the realization of a low-carbon society, KSN strives to create a new environment together with our customers. Here is an introduction to our efforts.
Introduction of our Efforts
Efficiency in safe and secure use of recycling and recycled products (Charcoal) to the customers through cooperation in the separation of plastics. Although it is dfficult for many customers to achieve 100% plastic removal.
After being machine separated these plastics are disposed using proper industrial waste methods. However, in view of the environmental impact, such incineration or similar methods,we are considering an effective solution to take advantage of these plastics.
At this time, KSN has developed a "sorting and washing facility of plastics" to effectively remove plastic from food waste, based on this cleaning solution, in partnership with power producers, we are taking advantage of the feature rich resource and we will start the demonstration test of the "power generation by methane gas".
In the future, for the food waste that we receive from our clients, we aim to improve further, the advanced cascade use and service, and perform a larger variety of efforts, that we can use in building a new recycling network. "
Greenhouse gas emissions have been proven to be the main cause of global warming. Carbon trading systems known as "Carbon Offsetting" are being implemented as a global initiative with the entry into force of the Kyoto Protocol. In the future, the socio-economics that surround us will also be required to undergo dynamic structural changes with carbon forefront in policy decisions.
In line with these trends, we are making efforts to create a carbon sink (storing carbon so it is not released into the atmosphere) based on our carbonization technology.
Carbonization is a technology that can store carbon contained in biomass as charcoal. Charcoal is derived from carbon absorbed by photosynthesis of plants, so when recycled charcoal is used as fuel (using thermal), the carbon dioxide generated by combustion is carbon neutral.
On the other hand, if the charcoal is used as a material, carbon derived from biomass can be effectively stored for the life cycle of recycled products, effective removing the carbon from the system. In addition, in regions where global warming has become a serious problem, agricultural land is attracting attention as a place for carbon circulation and storage. If the charcoal can be utilized and applied to agricultural land soil as an agricultural soil enrichment material, the net effect will be a reduction of atmospheric carbon as it becomes locked into the soil.
After confirming the effectiveness and safety of charcoal, we will proceed with research on the use of charcoal in agricultural land and soil, and develop a new recycling system using a carbon sink for biomass utilization.
Through the carbonization process there is a possibility of realizing a carbon sink. To recycle biomass requires energy such as fossil fuels and electricity, therefore, in our energy system with biomass itself converted into heat, we developed a system which can be used as a heat source which assist with further drying and carbonization, minimizing energy consumption.
As stated in the table below, a fixed amount of carbon is released through carbonization. Carbon emissions associated with the energy use however, depend on the type and properties of the biomass to be processed (such as increased drying energy due to the high water content of the biomass), since the energy consumption involved in processing may increase, constant monitoring of the energy consumption involved in processing is implemented to ensure the carbon balance is made to be negative.

KSN has for the realization of a low-carbon society, redesigning a new business model called "Circulating Symbiotic type agricultural production system". This system uses recyclable resources (food waste, wood waste) and turned into charcoal was utilized 100%, through use in agricultural production, petroleum and fossil fuels used in general agriculture derived products is reduced to the benefit of everyone in emitting businesses.
The core competencies of the system are as follows.
- All production materials (the soil, fertilizer, etc.) were obtained from our recycled resources charcoal substitute, to make the hydroponic agricultural systems.
- Using the factory waste heat and excess heat, and reduce fossil fuel use.
- Using charcoal as a fertilizer, by cascading use as a fuel, and reducing the use of fossil fuel.
- Agriculture vegetable residue generated in the production process (no diet part other than the part that can be eaten, such as leaves, stems, roots) plays used by all carbonization.
Recyclable resources from customers as well as carbon fixation by carbonization, by cascade use of recycled products, by approach from both sides of the effective use, recycling processes and products available in a manner that does not possible release of carbon, on the ground of you it will be considered to allow reduction of carbon.
Customers of KSN are able to visit and see the crops obtained by the reproduction and new agricultural production system by carbonization of recyclable resources, such as visits to facilities and welfare facilities of our new circulation model.
