Hazardous waste� �tonnes� ����� ����� ��� At the Fort Site� a significant increase in hazardous waste was observed in ����� However� a review of the data since ���� shows that the volume of hazardous waste in ���� represented an anomaly when compared to previous years� The volume of hazardous waste in ���� was in line with typical volumes of prior years� showing a decrease of ��% compared to ����� and within the expected range of hazardous waste for the Fort Site� On the other hand� total non�hazardous waste decreased by ��% at the Fort Site� driven by variations in construction activity� Waste quantities are expected to fluctuate� primarily based on facility demolition and construction activities� At the Moa Nickel Site� there was a decrease of ��% in both hazardous waste and total non�hazardous waste produced in ���� compared to ����� Non�hazardous waste decreased due to COVID��� restrictions� which caused a reduced number of workers and activities taking place on site� The overall quantity of waste sent to landfill decreased by ��% compared to the previous year� Hazardous waste decreased due to a reduction of contaminated soil� with sulphur sent to the contaminated waste deposit� Waste sorting has improved over the last few years� � Hazardous waste is defined by each local jurisdiction� Total amount of overburden� rock waste� tailings and sludge is included and discussed in the Tailings Management section of this report� At OGP� there was a significant decrease in non�hazardous waste compared to ����� In ����� ��% of a sulphur unit was dismantled� considerably increasing the amount of metal waste discarded� The remaining ��% of the sulphur unit was dismantled in ���� during the maintenance shutdown� In ����� record keeping and reporting of hazardous waste at OGP improved� with the inclusion of sand used for blasting equipment for surface preparation� Although ���� data shows a drastic increase in hazardous waste compared to ���� due to changes in the classification of this type of waste� the amount of hazardous waste produced aligns with that of previous years� All hazardous waste at OGP is sent to various companies licensed to receive and treat this type of waste in Cuba� The only type of waste sent to landfill is domestic in nature� Recycled waste at OGP depends on equipment replacements and life cycles� Restrictions due to COVID��� led to a decrease in maintenance activities� which consequently reduced the amount of recyclable waste produced� Total non�hazardous waste at Sherritt and its joint ventures decreased by ��% in ����� mainly due to reduced operational and maintenance work conducted at OGP compared to ����� On the other hand� hazardous waste saw an overall increase of ��%� mainly due to an anomaly in ���� at the Fort Site and to improved reporting at OGP� and not due to an actual increase of this type of waste� 2020 SUSTAINABILITY REPORT 99 Engineering innovative solutions for the Energas Joint Venture while cleaning up ocean debris.
