In a circular economy, there will be no consumption or wastage. That is how it is defined (see above quotes and links). "Manufacturers or retailers retain ownership of their products". In the case of coffee cups, there will be no waste - all components are recycled.
It looks like we will soon transition to a new economy anyway. We have no choice.
Economists forecast the end of growth
$this->bbcode_second_pass_quote('', 'T')he last few weeks has seen bad news for the global economy, with the US and Europe facing growth slowdowns, and even much vaunted economic powerhouses Brazil, Russia, India and China faltering unexpectedly. While mainstream economists continue to predict an ongoing 'recovery', other leading experts point to the end of growth as we know it for the foreseeable future.
Earlier this month, the International Monetary Fund (IMF) slashed its quarterly forecasts for global GDP growth from 3.3% to 3.1%, and revised down growth estimates for other major powers. The US forecast was downgraded from 1.9% to 1.7%, and Europe is expected to contract 0.6% rather than the originally estimated 0.3%. The IMF also downgraded growth forecasts for 2014.
Against this background, evidence has emerged that the era of booming economic growth is over, and that we are entering an age of permanently slow growth - at best.
However, Grantham now highlights two trends that could facilitate the transition to a more stable economy - declining fertility rates and the rise of renewable energy. Garnering data over the last 40 years, he demonstrates a "remarkable drop in fertility" in the US, Europe, the richer East Asian countries including China, and even South Asia and Africa. According to the more optimistic end of UN projections, if such trends continue global population would peak at 8 million by 2050 before declining to near 6 billion by 2100 - a process which could be sped up with appropriate policy measures.
Simultaneously, Grantham argues we may be on the cusp of "a great technological leap that for the first time is accompanied by less energy use – the technologies of solar, wind power, and other alternatives as well as electric grid efficiencies and improved energy storage." By 2025 to 2030, he observes:
"Both solar and wind power are likely to be cheaper than coal... once the capital is found and the project is built, a wind or solar farm delivers far cheaper energy than a coal-fired utility plant, at around one-third of the marginal cost of coal."
He estimates that "nonrenewable energy" could be completely replaced by renewables "in 30 to 50 years", during which the new technologies will become increasingly cheap and efficient.
But Grantham still concurs that these developments cannot herald a return to the era of high growth, although they might smooth the way toward a new economy that is "less overreaching, less hubristic, a lot humbler about growth and our use of resources, and more determined to live in balance with the natural energy we receive from the sun and the heat, food, and water with which we can sustainably be provided."
