Astellas' manufacturing plants, research centers, and offices are implementing a variety of initiatives with the aim of reducing GHG emissions.
Efforts to improve facilities, which include the introduction of high-efficiency equipment and the conversion to alternative fuels, are expected to make a significant contribution to reducing the level of GHG emissions generated by energy sources. Employees’ participation in energy saving through improvements of daily work is also important. To this end, each facility adopts a two-pronged approach, comprising measures related to equipment and energy-saving activities.
Different fuels (eg. fuel oil, city gas, LPG) used in steam boilers and other combustion equipment emit different amounts of GHG per unit of heating value.
Therefore, switching to a fuel that generates less GHG is one of our Climate Change Mitigation Measures.
Because fuel oil and kerosene generally produce more GHG than city gas, Astellas has been actively converting its steam boilers so that they run on city gas, LPG, and LNG instead of fuel oil and kerosene. This conversion of steam boilers at research and production bases was completed by fiscal 2011. These fuel conversions contribute the GHG emission reduction but also reducing SOx emissions that is one of the air pollutant substances.
Installation of Heat Pump Devices
Astellas is actively introducing heat pump technology that makes effective use of heat in the air when upgrading existing air conditioning equipment or installing new equipment. Going forward, we will pursue the introduction of heat pump technology after securing a stable supply of electricity.
Introduction of Energy Monitoring Systems
Knowing exactly how much energy we use does not directly lead to lower energy consumption. However, the ability to confirm the status of energy usage can assist the elimination of wasteful practices and the formulation of new strategies.
For these reasons, we have instituted a program to introduce energy monitoring systems at our facilities.
Using Renewable Energy
The direct use of renewable energy sources, such as the solar energy and wind, is the most effective method of mitigating climate change issues. Accordingly, Astellas hopes to actively introduce renewable energy technology where feasible.
The Group's Kerry Plant in Ireland brought online a wind turbine power generation station with a maximum output of 800 kW and a wood chip biomass boiler system with a maximum output of 1.8 MW from March 2012. In fiscal 2016, the full amount of 1,607 MWh produced by the wind turbine power generation station was used to power the facility. In addition, the wood chip biomass boiler also used 34,984 GJ of heat. Through these means, the total amount of GHG emission reduction came to 3,093 tons.
In Japan, the Tsukuba Research Center has installed photovoltaic generation systems. In fiscal 2016, the full amount of 47 MWh generated was used to power the facility. As a result of this initiative, the amount of GHG emission reduction came to 25 tons.
Overseas plants are engaged in an initiative to purchase electricity designated as being generated from renewable energies such as wind power or hydroelectricity, and of the electricity purchased in fiscal 2016, the Norman Plant purchased 12,237 MWh, the Meppel Plant 12,603 MWh, the Dublin Plant 6,200 MWh and the Kerry Plant 6,815 MWh of electricity generated by renewable energy sources. In addition, geothermal energy is being used in part of the Yaizu Pharmaceutical Research Center, in Northbrook (US), and in Leiden, the Netherlands. Leiden, which can quantify geothermal energy, used 1,236 GJ of geothermal heat, resulting in a reduction of 146 tons in GHG emissions.
