Unite and Ignite - The path to a circular economy

Unite and Ignite – The Path to a Circular Economy

“We see a world of abundance, not limits. In the midst of a great deal of talk about reducing the human ecological footprint, we offer a different vision. What if humans designed products and systems that celebrate an abundance of human creativity, culture, and productivity? That are so intelligent and safe, our species leaves an ecological footprint to delight in, not lament?”

This “new world,” explored in McDonough and Braungart’s novel, Cradle to Cradle– Remaking the Way We Make Things, almost sounds like a fairytale. And yet, the vision they pose is no longer a dream, because through necessity it must become a reality.

Making Circular Economy Truly Global (article)

For CE principles to take hold globally, it is imperative to have a cradle to cradle approach by nations and organisations through whole system optimization, material data tracking and big data warehousing. These initiatives can give rise to entire industries and improve data flow across the global economy. This can result in greater transparency across the global value chain.

Covering your Tracks: Why Landfills are a Necessity in Developing Nations

Landfills—what image does this word startle into your mind?

Is it a landscape smeared with trash, piled high in the blistering heat of the Sun, with tires and plastic bags, old T-shirts and banana peels? With waves of toxic gases spiraling off, the smelly sock odor burning your eyes and the thickness of the air constricting your lungs?

In fact, this is the negative connotation the word landfill has in most people’s minds, and I cannot say that I am excluded. Upon watching this panel, I was at first a little put off. We have come so far with sustainable technology, with waste-to-energy, biogas reactors, recycling, compost—and yet, for developing countries all we are calling for are landfills? Why do we want to keep piles of trash there? If it has taken developed nations so long to figure out that waste is a resource, why shouldn’t we immediately begin encouraging these treatment technologies in developing countries as well?

After 3R’s, Recover Energy from Waste or Landfill?

There is no ideal way to dispose of waste. All options are expensive and have myriad impacts, so waste managers need to select from among several challenging choices. Better decisions are made when the public is part of the decision making process and supports an ongoing waste management program. An “either/or” scenario between energy from waste and landfilling is rare. They must co-exist in an integrated system.

Food Waste Disposers Can Mitigate Climate Change and Reduce Costs

For climate change mitigation, food waste disposers are better than composting, waste-to-energy and landfilling. Their wider adoption calls for integrated decision making encompassing solid waste management and wastewater.

Untangling Behavioural Drivers Behind Food Waste

Put simply: Why do apparently rational consumers waste so much food? To discuss this further, be Waste Wise convened a panel of experts from both sides of the Atlantic to discuss and unpick the complex set of behaviours that lead to this.

The drivers behind phenomenal levels of food waste are complex and include food pricing, logistical and storage issues. However, given the significant level of waste that happens within the households of societies like the UK and US, it is useful and informative to consider those behaviours that drive this level of waste.
