Our two main products (insulation box, ice pack) are made using eco-friendly plastic, and Bio-mas, which is the main raw material from sugar cane. Eco-friendly plastics include EL724 (biodegradable resin) and EL727 (biomass synthetic resin), and we used EL727 which is easy to dispose of waste and can be recycled. The cooling box is a waterproof and cooling function box made by laminating Bio-PET and paper on corrugated cardboard, and can be separated and discharged as "paper." The ice pack is made of biomass PE alone without a sump processing, and after use, the contents (water) can be discarded and separated into "vinyls." Through the online frozen food (desserts including cakes) distribution business, the parent company DiWiPro Co., Ltd., I came across the cold chain system and realized how many EPSs and ice packs are used in the cold chain distribution process and adversely affect climate change and global warming. We realized the seriousness of these environmental problems and started developing eco-friendly cooling function boxes and eco-friendly ice packs, and started developing and selling sustainable eco-friendly boxes and ice packs through our subsidiary Botash Co., Ltd.
