Reman is about reusing the product's resources to create a smaller environmental footprint

Linköping University has prepared the life cycle assessments based on ISO 14040 and 14044. Afterwards, the LCAs, including methodology, data and interpretations, have been critically reviewed by the independent third party SustainX. All LCAs have an approved LCA statement, with the exception of the panel review requirement in ISO 14044.

All eight product groups have had their environmental impact assessed in individual LCAs focusing on three environmental impacts: Global warming (CO2eq emissions), energy consumption (MJ) and depletion of natural resources (Sb-eq), also known as depletion of abiotic resources. The environmental impact has been assessed throughout the entire life cycle of the product. This means from the extraction of raw materials, to the processing of components, to transport and distribution, the in-service phase*, as well as the disposal after the product has reached the end of its lifetime.

_{*Use phase is excluded in this LCA as it is assumed that the environmental impact of the use phase is the same for both remanufactured and newly produced products.} 

One product number from each of the eight product groups has been compared to the same product number from new production. We call this the functional unit. The product numbers are selected based on CPI and BORG Automotive's sales volume in 2021 and an estimation of the product's technological relevance in the next 5 years. 

A life cycle assessment has been prepared for each selected product number for both a remanufactured product system and a newly produced product system. An attribution model is used where the input and output flows in a system's process are calculated for a specific period based on historical data. This makes it possible to compare the environmental effects of the two product systems reman and new.

The environmental impact of materials and processes used for the primary product (newly manufactured product) is allocated to a first life cycle of the product. This means that if materials and components can be reused in the next life cycle (for remanufactured products), the environmental impact is considered "free" for that cycle. Thus, the environmental impact is always attributed to the first product life cycle in these life cycle assessments.

A remanufactured starter from CPI saves the environment 77% CO2eq, 80% energy, and 95% of the new materials compared to a newly manufactured starter.

A remanufactured AC compressor from CPI saves the environment 76% CO2eq, 72% energy, and 84% of the new materials compared to a newly manufactured AC compressor.

A remanufactured alternator from CPI saves the environment 82% CO2eq, 79% energy, and 91% of the new materials compared to a newly manufactured alternator.

A remanufactured brake caliper from CPI saves the environment 56% CO2eq, 55% energy, and 70% of the new materials compared to a newly manufactured brake caliper.

A remanufactured EGR valve from CPI saves the environment 57% CO2eq, 46% energy, and more than 99% of the new materials compared to a newly manufactured EGR valve.

A remanufactured steering rack from CPI saves the environment 78% CO2eq, 62% energy, and 96% of the new materials compared to a newly manufactured steering rack.

A remanufactured steering pump from CPI saves the environment 22% CO2eq and 94% of the new materials compared to a newly manufactured steering pump despite the 49% higher energy consumption

A remanufactured turbocharger from CPI saves the environment 32% CO2eq and 55% of the new materials compared to a newly manufactured turbocharger despite the 7% higher energy consumption.
