Eco-costs / value ratio

The Eco-Costs/Value Ratio (ECVR) is a useful tool for the assessment of the environmental impact of a product. This method links the value chain of a product to its ecological production chain to determine the added value and the corresponding costs for each step. In a market economy, the value of a product is expressed in money, while its eco-costs are measured in the form of the Eco-Costs/Value ratio.

The Eco-costs/Value Ratio model is a quantitative and economic allocation tool based on the Life Cycle Analysis (LCA) methodology. Currently, it is used to support product portfolio management and marketing strategies. This tool has the potential to be a useful competitive advantage for businesses that are serious about the environment.

Life cycle assessment

Performing a life cycle assessment is important for a variety of reasons. For one thing, it is a way to measure the environmental and socioeconomic impact of a product. A life cycle assessment can help design better products and services by taking into account all of their impacts throughout their life cycle.

Life cycle assessment is an extensive process. It involves identifying all of a product’s processes, materials, inputs, and outputs. It allows a more comprehensive and detailed analysis, and can lead to fascinating insights.

Equilibar, a Fletcher, North Carolina company, designs and manufactures fluid control instruments for science, industry and research. Its designs include vacuum control valves for NASA contractors. The company employs approximately 60 people in North Carolina and is among more than 3,800 suppliers nationwide.

The Equilibar EVR controls vacuum pressure to a very high degree of accuracy. This enables it to maintain vacuum at a required level, even during pressure fluctuations. It does this by using direct diaphragm sealing technology and a flexible diaphragm. Because the diaphragm is the only internal moving component, the device is highly efficient and able to react to changes in system flow rate within milliseconds.
