Establishment of a Recycling-Oriented Society

The Eisai Group in Japan is working to achieve zero emissions and conducting waste disposal with three goals in mind, specifically, reduce the amount of waste generated, increase the amount of recycled waste and decrease the amount of waste sent to landfill. In fiscal 2016, we attained zero emissions for the ninth consecutive fiscal year, and the total amount of waste generated by the Eisai Group in Japan successfully declined 15.7% from fiscal 2015. The amounts of waste acids, waste alkalis and waste oil decreased considerably at the Kawashima Plant, where the operation of the Synthesis Facility was terminated, and at the Kashima Plant, in which activities were shifted to those generating less waste liquid. At the Tsukuba Research Laboratories, we were able to eliminate the use of a coagulant in the wastewater treatment process and drastically reduced the amount of mixed sludge waste. At the same time, we promoted the thorough sorting of waste for recycling and the sale of wastepaper and valuable metals and glass, which also contributed to a reduction in the amount of waste generated by the Eisai Group in Japan. Despite an increase in the amount of waste sent to landfill by 3 tons over fiscal 2015, we recorded the ratio of waste sent to landfill to total waste of 0.43%, achieving the target of reducing the ratio to less than 1%. The recycling rate (including valuables) reached 62.8%, an increase of 5.1% compared with fiscal 2015.

Initiative for Recycling Resources

In order to promote the establishment of a recycling-oriented society, it is essential to reduce the amount of waste generated in addition to reusing and recycling resources such as metal, glass, waste oil and paper products from waste. Based on this perspective, we actively promote the sale of equipment and devices for reuse as well as the recycling of scrap metal, glass bottles and waste oil. Also, to reduce the total amount of wastepaper, we are promoting the sale of wastepaper while avoiding generation of unnecessary waste by devising better ways to proceed with meetings and to copy documents. We have expanded the scope of our efforts to promote the sale of wastepaper in Japan from operational sites and the head office to include sales offices. We also continue to reuse organic solvents, such as those used in the manufacture of active pharmaceutical ingredients, and sell these as auxiliary fuel.

Onsite Inspections of Waste-Processing Companies

The Eisai Group in Japan has been conducting regular onsite inspections of its waste disposal contractors. For the purpose of checking that waste is being disposed of properly, periodic inspections are carried out for contractors engaged in the collection, transport, intermediate processing and final disposal of waste. During fiscal 2016, a total of 65 onsite inspections were conducted by the Eisai Group in Japan at sites around the country, and it was confirmed that waste is being disposed of in an appropriate manner.

For potential new contractors, we conduct careful screening that includes onsite inspections. At Eisai Co., Ltd., in particular, new contracts are only signed after deliberation and approval by the Company-Wide Environment and Safety Committee, with priority given to government-certified excellent industrial waste management contractors.
