Samuel quickly recognized the overwhelming litter problem in Kenya. Everywhere you look in areas where people live, there is rubbish by the sides of the street, around people’s homes, in school playgrounds, in bushes and trees, in rivers, in the sea and on the beaches.
He and his people gather up and recycle the ubiquitous plastic pollution into construction materials.
“Basically we are substituting plastic for cement,” explained Ngaruiya in an interview with Reuters. The US-trained engineer went on to explain that when the melted plastic cools, it absorbs and “squeezes” the sand, creating a compact and rather strong building material.
The idea is simple: pay locals to gather up plastic debris and pollution, and then repurpose it into useful construction materials (fence poles, roof tiles, road signs, flooring, containers, etc.).
The new BAMB Materials Passports platform will fill a gap in the marketplace by providing a ‘one-stop-shop’ to describe Circular Economy value across the building cycle, especially for using and re-using components and materials, and reducing generation of waste.
BAMB 2020 is creating new business models to accelerate a circular use of materials, building components and/or building elements.
The business models will look into ways to create added value for each stakeholder and the identification of current bottlenecks within this new value chain. Developing business models will also require the identification of the business capabilities that are needed to be built/enhanced for the prioritized business components. Read More
Almere, a large city in the Netherlands starts with the development of an ecological residential area.
The future residents will live in an ecological area with energy-efficient homes and where waste water treatment is organized naturally.
The houses in the ecological district in Almere will be developed with well-insulated facades, triple glass and wooden windows. In addition, wall heating is combined with solar panels and integrated ventilation. According to the developers, the CO2 impact is less than 10 percent compared with a regular house of concrete and steel. Read More
Miners use their bare hands to filter out precious minerals using a sluice. These countries can be compensated of we agree on international quotas for minerals
Critical minerals are running out too fast: there should be quotas
Last week, Theo Henckens has been promoted on this worrying thesis. “We need a kind of international agreement on minerals.”
Molybdenum is a mineral that is essential in the production of high-grade stainless steels. But within 80 years Earth will be running out of molybdenum, like many other major minerals. By the end of this century there will be a shortage, unless the reuse of molybdenum will be drastically increased. Read More
Hundreds of volunteers helped to restore coast Alabama, building oyster reefs
We need to protect our coasts from global warming and – because of that – the sea level rising. But should we only use concrete seawalls?
Why not use nature against nature. Or a combination with classic engineering?
It’s a beautiful, natural coastal protection and soften shoreline defenses are multifunctional. It’s attractive to all kind of sea lives, tourism, fisherman and therefore a whole industry behind. Let’s have a look at alternatives. Read More
how to keep the climate comfortable in buildings, without energy-intensive installations
Do you also have dry eyes and headaches in your office building? This new Facade System allows a building to ‘breathe’. Tobias Becker used biomimicryfor a pleasant indoor climate.
The German engineer Ing. Tobias Becker has developed a glass facade system that requires minimal energy to generate a pleasant indoor climate. The system allows air through holes and makes buildings ‘breathe’. Read More
Previously, the standard was “the more fuel you burn, the harder you work. Nowadays, this attitude has changed into a sport to reduce as much as possible, according to the certified construction companies
Construction companies, which are certified for the CO₂-Performance policy, achieve 3.2% CO₂ reductions per year.
Remarkable, while the national trend is that CO₂ emissions are increasing. Thais was reported by a new Dutch research team. Read More
Daan Roosegaarde introduces the Free Smog Tower: a 7 meters high tower that creates smog-free air in the area.
“It’s my job to look around, and find new proposals to solve global issues. I have been involved in fashion and highways. And since 2014, I am involved in smog.”
Daan Roosegaarde introduced the ambitious idea for the Free Smog Tower. He started a Kickstarter Project with the goal to built a 7 meters high tower in Rotterdam that creates smog-free air in the area. Read More
