Unlike the linear economy, where we “take, make, use, dispose”, the circular economy seeks to imitate the life cycle of nature. Everything is reused following a sustainable design model, giving the item new value and extending its useful life. In addition to reducing its environmental impact, we can save money and resources throughout the entire value chain, optimize our use of energy, and reduce waste.
We currently have different tools to assess the environmental profile of a product to know how we can incorporate adjustments to achieve an ecological design in accordance with established standards. These tools include: the life cycle analysis (LCA), the carbon footprint and ecological footprint calculation, and the assessment of the product's environmental strategy. However, life cycle analysis is considered to be the most comprehensive methodology for assessing the impact of the item or service on the environment, as it quantifies both "input" (energy resources, raw materials) and "output" (environmental emissions and waste) variables in the value chain.
