Hybrid solar panels for electricity and heat

I’ve written in the past about passive solar heat, such as Trombe walls, solar furnaces or solar heating walls. The idea is more familiar is solar hot water systems. But did you know that solar heat and solar electricity can be combined? Hybrid solar panels have been on the market for a while, but the […]

Three ways to deal with plastic bottles

Last year there was a fairly high profile report on plastic waste, and it generated a lot of discussion. It showed that of the 78 million tonnes of plastic produced globally each year, only 2% gets recycled back into new plastics. 40% ends up in landfill, and just short of a third goes into the […]

The world’s first mall for recycled goods

Last week I wrote about the Edinburgh Remakery, and how they are trying to foster a culture of repair. It’s one of the most shared posts I’ve ever written, and there’s clearly a real interest in this whole idea. Lots of you have been in touch to share similar projects, including this one from Sweden. […]

Why the world needs waterless toilets

The other day I was opening a charity magazine and found an insert from Practical Action inside. It’s about toilets in Bangladesh and I’ve seen it a couple of times now. Before I start, a word of warning – if you’re reading this over lunch, maybe come back later. The story in the flyer is […]

A creative use for Britain’s bread waste mountain

Despite the best efforts of campaigners over the past few years, food waste remains deeply entrenched in our food system. Reducing or eliminating waste is still the priority, but there will always be wastage in the system somewhere. That’s where we need to put our circular economy hats on and work out how to put […]

How to bring a tower block into the 21st century

Buildings last a long time. A good one will be enjoyed for generations to come, sometimes for centuries into the future. Build a bad one, and it will be disliked and resented for a couple of decades and torn down as soon as it makes economic sense – but that’s often far longer than people […]
