Otsuka Pharmaceutical and Taiho PharmaceuticalCommence Material Recycling of Waste PTP Used in Pharmaceutical Packaging
Otsuka Pharmaceutical Co., Ltd. (Otsuka) and Taiho Pharmaceutical Co., Ltd. (Taiho) announced todaythat they have started a material recycling initiative for press-through packaging (PTP) waste generated
during pharmaceutical packaging. The initiative commenced in May 2024.
This material recycling initiative seeks to reduce environmental impact by recycling PTP waste generated
by Otsuka and Taiho. It utilizes technology to separate PTP sheets for packaging tablets and capsules
into plastic and aluminum foil and includes a modal shift to rail transport, thereby helping to reduce CO2emissions.
Material Recycling Process

Based on the 2050 Environmental Vision “Net Zero”, the Otsuka group aims to reduce the total
environmental impact of its business activities to zero. In line with this vision, the group has identified
carbon neutrality, circular economy, and water neutrality as material issues and is implementing initiatives
to achieve these goals.
Previously, considering the CO2 emissions from transportation, PTP waste generated at each factory*3of both companies was incinerated by commissioned waste disposal companies. The thermal energy
from incineration was recovered, and the incineration ash was reused as part of the raw material forconcrete.
Through the collaboration between Otsuka and Taiho, both part of the Otsuka group manufacturers oftablets and capsules will enable an efficient modal shift, making it possible to recycle all PTP
polypropylene sheet packaging waste generated at the two companies. As a result, compared toincineration, this initiative will reduce CO2 emissions by approximately 94%, and allow about 55 tons ofwaste materials to be reused annually.
Otsuka and Taiho will continue to work toward the realization of a decarbonized and sustainable society
by actively introducing renewable energy, maximization of energy-use efficiency, and effective use ofresource, including this initiative as part of its activities contributing to a carbon neutral and circulareconomy.

Aiming to create a healthy future as a total healthcare company, the Otsuka group has established the2050 Environmental Vision, “Net Zero,” with the aim of reducing total environmental impact across all ofits business activities to zero. Based on this vision, the group has determined the material issues for its
environmental initiatives to be carbon neutrality, circular economy, and water neutrality. For carbon
neutrality, the group has set a global medium-term target of a “50% reduction in CO2 emissions by 2028
compared to 2017.” For circular economy, the group has set a global medium-term target of a “50%reduction in simple incineration and landfill disposal by 2028 compared to 2019.” Moving forward, theOtsuka group will continue to leverage synergies realized in collaboration among group companies andwork in unison on sustainability-related activities.

Aiming to achieve the group’s carbon neutrality target, both companies are adopting renewable energy,
including the introduction of CO2-free electricity, utilization of green power certificates, and installation ofsolar power generation equipment, in addition to maximizing energy use efficiency. In terms of a circular
economy, the companies are striving to help build a recycling-oriented society while coexisting
appropriately with the world’s limited resources by minimizing waste generation, promoting resource
recycling, and improving resource utilization efficiency across the entire value chain.
