How Sims Limited Mitigates Greenhouse Gas Emissions

Sims Limited is part of a value chain that diverts materials from landfill. These diverted materials are sorted and then refurbished, parts harvested, or recycled to make new products. By keeping resources in use at their highest value for as long as possible we enable the circular economy and help mitigate greenhouse gas (GHG) emissions. Most secondary materials require significantly less energy to transform into products than primary ones, which is why the circular economy and climate change are inextricably linked. Secondary reuse also protects our world’s natural resources.

To provide a clearer view of the value of materials recovery as it relates to emissions avoidance, we calculated the emissions reduction enabled by the Sims Limited value chain. We researched available literature and used several sources to define a range of potential savings based on those studies. The chart below shows a range of potential savings due to differences in processing technologies, the source of energy and variations in published data.

Despite variations, the research shows that the recovery of metals will always be beneficial over primary production.

Below, we provide an assessment of the emissions reduction Sims Limited’s value chain enabled based on a representative range for a world average.
