Circular economies aim to keep materials out of waste by creating designs for reuse and redesigning products to reduce resource intensity, as well as recovering waste from technical cycles (for instance reprocessing photocopiers or MRI machines), leading to reduced land and water pollution, limited biodiversity loss and energy consumption.
This would significantly help decrease land and water pollution levels as well as limit biodiversity loss while simultaneously cutting energy consumption costs.
Reduce
Every company -- regardless of industry or size -- can enhance resource efficiency by adopting circular concepts in their production processes. Start by gathering all relevant production data to gain a fuller understanding of where resources are utilized; identify areas in which circular principles could help reduce waste while maintaining more sustainable supply chains; then implement those principles to maximize resource efficiency and ensure maximum resource efficiency.
Traditional production models that rely solely on extracting and using natural resources no longer seem viable as world reserves of oil, minerals and other raw materials are being consumed at an unprecedented pace. But thanks to the emerging circular economy model there may be hope. As shown by its system diagram below, circular economies repurpose materials instead of taking them from the earth and using them directly; rather they are recycled through multiple stages before returning back into nature once manufacturing has concluded.
This can be seen everywhere from the petrochemical industry's recycling of oily sludge into new products to your daily life when recycling your old sneakers correctly. The goal is to turn waste into valuable material streams while decreasing fresh raw materials need, thus mitigating climate change impacts by slowing resource use and decreasing landfill and ocean pollution.
Key to circular design is considering repairability and disassembly for reuse or resource recovery. One company doing just this is iFixit; their extensive library of repair guides, step-by-step instructions and tools allow users to keep electronic devices working longer instead of disposing of them prematurely.
Companies that choose circular business practices can reduce their environmental impact by selecting eco-friendly materials, designing their products to be easily recyclable, and setting up collection and processing systems to reduce contamination. By adopting these strategies, companies may reduce their ecological footprint by up to 80% - an impressive accomplishment towards creating a healthier planet and more robust business models.
Reuse
Our current take-make-consume-throw-away model is unsustainable, and it is time for us to move towards a circular economy. A circular economy seeks to keep materials and products in use as long as possible so as to maximize all resources put into producing them - this means keeping production to an absolute minimum, when necessary; when required for production use materials with long lifespan so they may be reused longer term.
Transitioning to a circular economy requires an unprecedented change in our use of resources. Instead of the linear "take-make-consume-throw away" model that has dominated manufacturing since the first Industrial Revolution, companies must examine how to redesign products, materials and processes so as to be less resource intensive while recapturing so-called waste as raw materials for new products - this might include extending the lives of existing products or repurposing them for other uses such as food scraps or organic waste or even electronic devices that would otherwise end up in landfill.
To do this, companies should develop products with a circular mindset from the outset and ensure their materials can be reused as raw material again and again. This may involve using recycled materials which reduce extraction from the earth; or by reusing materials in products and components which decreases product production needs; finally product designs must allow for parts to be repaired through Extended Producer Responsibility programs such as bottle deposit laws or repair cafes offering free services to fix electronics and household goods.
Circular economies offer many benefits beyond reducing material consumption and eliminating waste, including reduced operating costs by cutting energy consumption and emissions from transportation. They can also help minimize our dependence on natural resources while protecting climate by limiting greenhouse gases released during production of new products.
Recycle
Globally, we must move away from our traditional linear economy of take-make-consume-throw away. This outdated model is not only unsustainable - given that Earth only has limited resources - but inefficient as well. According to Evan Tylenda of GS SUSTAIN, moving towards circular economy offers immense cost savings and improved performance metrics for companies.
The circular economy aims to reduce waste and pollution while actively improving the environment, by turning waste into valuable materials that can be recycled into new products or kept in circulation longer than their expected lifetime.
By switching to renewable energies such as wind or solar power, non-renewable sources like fossil fuels and synthetic chemicals are no longer used as sources of power in our economy. Instead, renewable sources are utilized and unneeded materials returned back into the soil so they may be harvested again later.
Implementing the circular economy requires businesses to redesign their products and processes to be less resource intensive, such as replacing difficult-to-recycle materials with more sustainable options or providing modularity and serviceability capabilities that enable customers to repair or replace products more easily.
Another key element of circular economics is designing products to promote reuse and sharing assets and services among different participants. Fairphone was an early leader in adopting such practices with their smartphone designs; these devices can easily be taken apart and reassembled for repair or reuse purposes.
Transitioning to a circular economy can bring many economic advantages, including creating jobs, increasing economic efficiency and decreasing raw material imports. But doing so presents its own unique set of obstacles: one is breaking through inertia in current production systems requiring significant investments in technology and infrastructure for successful transition. Another challenge lies in shifting consumer perceptions regarding what constitutes sustainable products or services (some consumers may hesitate purchasing non "green") yet corporations have the chance to embrace circular economic models and reap its many advantages.
Renewable Energy
Circular economies integrate renewable energy sources from their inception into products and services, offering an alternative to the current linear model that relies on cheap raw materials and fuels for production. Their design process prioritizes energy efficiency, eliminates waste production and promotes renewable alternatives to fossil fuels for electricity generation - helping address climate change with reduced greenhouse gas emissions and greenhouse gas emissions.
Since the Industrial Revolution, linear economic models have been the dominant system. Unfortunately, this model has proven unsustainable, leading to global resource depletion. Therefore, transitioning towards circular economies - where waste reduction and renewable energy sources are prioritized over traditional linear models - must take place - not only will this protect our environment but it will also create jobs through new business models focused on reuse, repair and remanufacture that create millions of new jobs globally.
This circular economy approach marks a dramatic departure from the linear model that has long characterized manufacturing. This "closed loop" with raw materials has not proven sustainable; unfortunately, our world cannot rely on an finite supply of inexpensive materials and energy sources indefinitely. Businesses should start planning now for moving towards circular economy models.
Transitioning to a circular economy will be challenging, yet achievable. All members of society must come together in making changes from technical product designs to shifting consumption habits. Companies can lead by making sure their production processes are environmentally friendly while engaging suppliers and customers to understand their needs and preferences.
One key challenge will be redesigning products to maximize durability, reusability and disassembly while transitioning away from B2C (business to consumer) relationships and into C2C relationships (cradle to cradle). We must also find ways to minimize carbon emissions from energy and material processes - which means moving away from fossil fuels like coal - by using technologies which upgrade existing systems with renewable alternatives or replace fossil-based ones altogether.
