So far we have removed a total of 54,041m2. We will remove the remaining asbestos successively by FY2013, except for that in buildings where refurbishment is planned. We also take environmental measurements once a year to check for airborne asbestos fibers from the remaining asbestos-containing spray-on materials.Asbestos RemovalRemoval of asbestos-containing spray-on materialsStorage of PCB WastePCB-containing transformers and capacitors are stored in each research base and site PCB waste is stored as specially-controlled industrial waste in a designated storage area in each research base and site, and checked for stored conditions once a month by the Specially Controlled Industrial Waste Managers. In FY2011, 2 capacitors stored at AIST Tohoku and 34 capacitors stored at AIST Tsukuba were transported to Japan Environmental Safety Corporation (JESCO) for treatment and disposal.0%20%10%40%30%60%50%80%90%70%100%FY20076,938㎡FY20089,285㎡FY20103,873㎡FY2012 to FY201327,959㎡FY200916,127㎡FY201117,818㎡Change in the area of removed asbestos-containing spray-on materials(Unit:㎡)We store and monitor PCB waste continuallyEnvironmental Report|55
