Due to the ever-increasing demands of the global economy, the resources of the planet are being used up at an alarming rate and waste and pollution are growing fast. The idea of a more sustainable “circular economy” is gaining traction, but what does this concept mean, and can it help save the planet?
1) Business as usual, the path to catastrophe
Unless we make some major adjustments to the way the planet is run, many observers believe that business as usual puts us on a path to catastrophe.
Around 90 per cent of global biodiversity loss and water stress (when the demand for water is greater than the available amount), and a significant proportion of the harmful emissions that are driving climate change, is caused by the way we use and process natural resources.
Over the past three decades, the amount of raw materials extracted from the earth, worldwide, has more than doubled. At the current rate of extraction, we’re on course to double the amount again, by 2060.
According to the International Resource Panel, a group of independent expert scientists brought together by the UN to examine the issue, this puts us in line for a three to six degree temperature increase, which would be deadly for much life on Earth.
2) A circular economy means a fundamental change of direction
Whilst there is no universally agreed definition of a circular economy, the 2019 United Nations Environment Assembly, the UN’s flagship environment conference, described it as a model in which products and materials are “designed in such a way that they can be reused, remanufactured, recycled or recovered and thus maintained in the economy for as long as possible”.
In this scenario, fewer resources would be needed, less waste would be produced and, perhaps most importantly, the greenhouse gas emissions which are driving the climate crisis, would be prevented or reduced.
This goes much further than simply recycling: for the circular economy to happen, the dominant economic model of “planned obsolescence” (buying, discarding and replacing products on a frequent basis) would have to be upended, businesses and consumers would need to value raw materials, from glass to metal to plastics and fibres, as resources to be valued, and products as things to be maintained and repaired, before they are replaced.
3) Turn trash into cash
Increasingly, in both the developed and the developing world, consumers are embracing the ideas behind the circular economy, and companies are realising that they can make money from it. “Making our economies circular offers a lifeline to decarbonise our economies”, says Olga Algayerova, the head of the UN Economic Commission for Europe, (UNECE), “and could lead to the creation of 1.8 million net jobs by 2040”.
In the US, for example, a demand for affordable, high-quality furniture, in a country where some 15 million tonnes of discarded furniture ends up in landfill every year, was the spur for the creation of Kaiyo, an online marketplace that makes it easier for furniture to be repaired and reused. The company is growing fast, and is part of a trend in the country towards a more effective use of resources, such as the car-sharing app Zipcar, and Rent the Runway, a rental service for designer clothing.
In Africa, there are many projects, large and small, which incorporate the principles of the circular economy by using existing resources in the most efficient way possible. One standout initiative is Gjenge Makers in Kenya. The company sells bricks for the construction industry, made entirely from waste. The young founder, Nzambi Matee, who has been awarded a UN Champion of the Earth award, says that she is literally turning trash into cash. The biggest problem she faces is how to keep up with demand: every day Gjenge Makers recycles some 500 kilos of waste, and can produces up to 1,500 plastic bricks every day.
4) Governments are beginning to step up
But, for the transition to take hold, governments need to be involved. Recently, major commitments have been made in some of the countries and regions responsible for significant resources use and waste.
The US Government’s American Jobs Plan, for example, includes measures to retrofit energy-efficient homes, electrify the federal fleet of vehicles, including postal vans, and ending carbon pollution from power generation by 2035.
In the European Union, the EU’s new circular economy action plan, adopted in 2020, is one of the building blocks of the ambitious European Green Deal, which aims at making Europe the first climate-neutral continent.
And, in Africa, Rwanda, Nigeria and South Africa founded the African Circular Economy Alliance, which calls for the widespread adoption of the circular economy on the continent. The Alliance supports African leaders who champion the idea, and creates coalitions to implement pilot projects.
5) Squaring the circle?
However, there is still a long way to and there is even evidence that the world is going backwards: the 2021 Circularity Gap Report, produced annually by the Circle Economy thinktank, estimates that the global circularity rate (the proportion of recovered materials, as a percentage of overall materials used) stands at only 8.6 per cent, down from 9.1 per cent in 2018
So how can the world be made “rounder”? There are no easy answers, and no silver bullet, but Ms. Algayerova points to strong regulation as a big piece of the puzzle.
“I am proud that for the automotive sector, a UN regulation adopted at UNECE in 2013 requires 85 per cent of new vehicles’ mass to be reusable or recyclable. This binding regulation influences the design of around one quarter of all vehicles sold globally, some 23 million in 2019.”
“It’s a step in the right direction, but these kind of approaches need to be massively scaled up across all sectors”, she adds. “Shifting to the circular economy is good for business, citizens and nature, and must be at the heart of a sustainable recovery from the COVID-19 pandemic.”
