138 Rubén Abruña: keeping our poop in the loop

Award-winning documentary film maker Rubén Abruña helps us dig into one of the oldest problems in civil society…
All around the world, there are serious problems caused by the various ways we deal with our toilet waste – all the poop and pee we humans create every day. We waste drinking water – Flushing toilets use massive amounts of water – for example, in a country like Switzerland, each person will flush over 40 litres a day down the toilet. Often, the sewage from water toilets is mixed with household waste water, so it’s now contaminated with microplastics, cleaning chemicals, contraceptives and drug residues. And then, in most western societies, all that liquid waste is then mixed with industrial waste. So now we’ve got massive volumes of pretty toxic stuff to try and clean up, and separate into drinkable water and solid waste.
In developing countries, millions of people still use open toilets, or have to defecate on the land around their houses. So here, there are massive issues with disease and vermin, and in some areas, even a safety risk from predatory animals.
What’s more, we’re wasting precious resources, too. Our human pee and poop contains valuable nutrients, including significant quantities of nitrogen, phosphorus and potassium – NPK – the key elements that we need to growing food and other crops. Instead, we’re using expensive fossil fuels and synthetic chemicals to provide these macronutrients.
Back in his homeland of Puerto Rico over 20 years ago, Rubén Abruña experienced a sanitation epiphany when he sat on a dry toilet for the first time. He was amazed that he could poop using no water, leaving no stink, and that the deposit could be safely composted into fertilizer, without polluting the environment. It drove him nuts that more people were not doing the same, and this prompted him to make the award-winning film “Holy Shit: Can Poop Save the World?”
Rubén has over 30 years of experience in the film, television, and radio industries. He has written, produced, directed, and edited numerous documentaries, broadcast journalism stories, and educational programs in New York, San Juan, Miami, and Zürich.

Circular Economy Podcast Episode 46 Gary Giles - OGEL

Episode 46 Gary Giles – OGEL

Gary Giles is another entrepreneur inspired by the circular economy. Gary set up his company, OGEL, to use a material that is quite difficult to recycle and very bulky, so transporting it to be recycled is expensive. We’ll hear how Gary was inspired by the modular design of Lego, and how he’s developed a way of constructing durable buildings that use only 3 shapes, are easy to assemble and need very few tools. Plus Gary tells us what a ‘full stop product’ is!

Transforming plastic waste into social value

Across Africa, and much of the world, end-of-use plastic is not collected for proper recycling. Instead, it is burnt; ends up in drains, sewers, fields and rivers; or in unprotected landfill, allowing toxins and microplastics to leak out. This is one of the hidden costs of our modern ‘linear’ economy – take, make and waste. Four entrepreneurs are turning that plastic waste into value – creating jobs for both disadvantaged and skilled people, improving local environments, and helping people find a purpose. We dig into their business models and hear their top tips for circular startups

Circular Economy Podcast Episode 23 Andy Bownds Eco Brixs

Episode 23 Andy Bownds – Eco Brixs

EcoBrixs Mission is “To create green, environmentally friendly, sustainable solutions to lift people out of abject poverty in Uganda”, and it does that by giving trash – waste plastic – a value. That means anyone in the community can recycle.
Eco Brixs started out in 2017. Frustrated with the lack of waste management systems in Masaka, Andy Bownds and his team started collecting plastic in his back garden, and after collecting 2 tonnes, decided to start a simple plastic collection facility called ‘Masaka Recycling Initiative’.
They went further, creating a circular economy solution to recycle plastic which would help support the local communities and economy. They developed an innovative plastic-sand composite paver which has been proven to be stronger, lighter and more durable than concrete. Fast-forward to 2019, and Masaka Recycling Initiative has now evolved into ‘Eco Brixs’, one of the largest recycling facilities outside of Kampala.
