Nowadays, “one man’s trash is another man’s treasure” has never been truer. We’re turning garbage into anything from furniture to vodka, and it seems we can push the limits even further. Engineering group Arup is proving just that, proposing the use of food waste in building materials.
The report aims “at demonstrating that a different paradigm for materials in construction is possible.” This could be done by diverting, in part, organic waste that is traditionally managed through landﬁll, incineration and composting to become a resource for the creation of construction engineering and architecture products.
According to Arup, bananas can produce textiles, while mushrooms can grow actual towers. It seems, with food waste, it’s best to let one’s imagination run wild — and for good reasons.
Using food waste for building materials would help create a circular economy where organic waste, instead of being disposed, is the main resource… This would help ameliorate rising levels of waste and shortfalls of raw material, as well as providing the industry with cheap, low carbon materials.
Looking to renovate your home? No need for concrete fillers — just use rice!
Thanks to over-harvesting, over-fishing, and overdoing pretty much everything, alternative food sources are all the rage. In the near future, the dory in your fish taco could be lab-grown. Your oatmeal may even be 100% renewable. And, if Chinese scientists prove it a success, rice will flourish in saltwater and create enough food for 200 million people.
The rice was grown in a field near the Yellow Sea coastal city of Qingdao in China’s eastern Shandong province. 200 different types of the grain were planted to investigate which would grow best in salty conditions.
Per hectare, scientists predicted an output of 4.5 tons. Much to their surprise, and because nature is cooler than we think, the yield hit 9.3 tons. With 1 million square kilometers of previously unused high-saline land now on the market, rice production could rise by 20%.
“If a farmer tries to grow some types of saline-tolerant rice now, they most likely will get 1,500 kilograms per hectare. That is just not profitable and not even worth the effort.” [says team leader Yuan Longping.]
A kilogram of the stuff goes for around $8, a whopping eight times more costly than regular rice. Still, some six tons have already made their way into kitchens. Beyond everything, the price is rice!
