Thankfully, the days of ‘sustainable’ meaning a pair of hemp sandals and a rickety bicycle are long gone. The threat of climate change has sparked a huge range of clever projects and concepts that enable consumers to go green without getting their hands dirty. Our sustainable technology wishlist below shows off four of the smartest sustainability solutions to hit the market – could one of them be coming to home or business near you?
It may look more like a cartoon car than a slick ride, but with zero emissions and no queues at the petrol pumps, maybe the Renault Twizy really could ‘reinvent your city life’. As well as being powered by a lithium-ion battery rather than emissions-producing fossil fuels, the Twizy switches to energy recovery mode when you lift your foot, has an ‘econometer’ that shows your energy consumption, and the car can be recycled at the end of its life.
Could the future of fuel be literally as well as figuratively green? As any schoolchild knows, plants generate energy from sunlight through photosynthesis, and Algenol Biofuels has plugged into this piece of natural genius by using the chlorophyll in algae to create fuel. Algenol produces gasoline and diesel to fulfill the huge commercial demand, but the CO2 produced by these fuels is absorbed by the algae and reused as one of the raw ingredients of photosynthesis. This recycling results in a carbon footprint that’s over 60% smaller than petroleum. The system is still in the process of commercialisation, but the science behind the concept suggests that these giant bags of green juice could be the new alternative to black gold.
Food shortages are predicted to be one of the biggest long-term issues relating to climate change, as rising sea levels put pressure on space and extreme weather destroys crops. Sky Greens’ vertical agriculture system means that crops can be grown in a high-rise system perfect for urban environments where space is at a premium, and using far less water and energy than conventional farming. The award-winning system from Singapore rotates tiers of growing troughs to ensure they all receive the maximum sunlight and nutrients for efficient production.
This ingenious idea relies on some clever chemistry to solve a very common but intractable problem. 50 billion plastic water bottles are used every year, and, once they get thrown into landfill, they take a minimum of 450 years to decompose. The Ooho liquid packaging system contains water in a thin, edible membrane made from calcium chloride and a seaweed derivative called sodium alginate. Even if you don’t fancy snacking on the membrane, it will quickly biodegrade. If the Ooho catches on it could not only reduce waste, but also the energy and chemicals used to produce disposable bottles.
All these clever products are designed to minimise the environmental impact of consumers and businesses, but in our day-to-day lives there will always be some unavoidable emissions. Celestial Green Ventures’ innovative method allows you to balance your impact through verified Natural Capital Credits, which certify the CO2e avoided from being emitted through our Trocano Araretama REDD+ Project. Find out more about how you can balance your emissions with Celestial Green Ventures through the use of Natural Capital Credits.
