Resource: Carbon Impact Studies: Cutting tools
This report summarises the method and outputs of a short-cut “carbon footprint” of a remanufactured cutting tool over new cutting tool.
Tuesday, 21st July 2009
ScenarioThe analysis was based on the real-life data collected from a tool remanufacturer with the assumption of a 5-times remanufacturing cycle for each new tool. In practice this figure will be dependent on the type, shape of the tool. The inventory of component impacts included materials, energy, transport logistics, remanufacturing ratio for each part, and disposal and waste scenarios.
FindingsIn summary, the carbon impact of remanufacturing cutting tools is considerably lower than that of new ones due to savings in production of materials with high embodied energy (special alloys): Only one fifth of the carbon burden of a new cutting tool is required for remanufacturing. In absolute terms, the carbon impact per kg of tool of a remanufactured end-mill is 1.3 kgCO2e compared to 6.4 kgCO2e of a new end-mill tool. Based on the sales figures in 2008, there is potential saving of 0.5 million tonne CO2e is available if remanufacturing cutting tools is fully adopted across industry.

FER warns against engine reman fraud
The Federation of Engine Remanufacturers (FER) has asked the industry to be on the look-out for suspicious engine remanufacturers, after increased fraudulent activity and "sub-standard and unprofessional work".
