Introduction to Circular Economy
A linear economy is a traditional model of production and consumption that follows a take-make-dispose approach. In other words, natural resources are extracted, materials are processed, goods are produced, and then they are discarded as waste. This model is based on unlimited availability of resources and assumes that waste can be safely disposed of without any negative impact on the environment. However, this model is not sustainable, as it leads to resource depletion, environmental degradation, and pollution.
In contrast, a circular economy is a regenerative model that aims to keep resources in use for as long as possible, reduce waste, and minimize negative environmental impact. In a circular economy, waste is seen as a resource that can be reused, repurposed, or recycled. The circular economy model is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems.
An example of a circular economy in action is the recycling of aluminum cans. Aluminum is a valuable material that can be recycled indefinitely without losing its quality. By recycling aluminum cans, we reduce the need for extracting new aluminum and save energy. This process also reduces the amount of waste that ends up in landfills.
Another example is the use of biomimicry in product design. By studying the natural world, designers can create products that are inspired by nature and mimic its efficiency. For example, the Japanese bullet train was designed to mimic the beak of a kingfisher bird, which allows it to travel at high speeds with minimal noise and resistance.
Overall, the circular economy model is a more sustainable and regenerative approach to production and consumption than the traditional linear economy model.
