100% Biodegradable Sanitary Pads
solution: added 7th December, 2018

Saathi Eco Innovations India Private Limited

100% Biodegradable Sanitary Pads

Saathi is a purpose-driven sustainable manufacturing company that makes eco-friendly hygiene products. Saathi’s mission is to create hygiene products that are good for the body, environment, and community. Saathi’s 100% biodegradable sanitary pad is made from an agricultural by-product, banana fibre, one of the most absorbent and abundant natural fibres in India. Unlike wood pulp or cotton, the raw materials for Saathi’s sanitary pads don’t require additional land. They also don’t contain any bleacher chemicals, thereby minimising skin irritation and the release of toxins into the environment upon disposal.

Hexafly

Insect-based protein for aqua feed

Hexafly are developing new material sources for the aqua feed, chitin and plant nutrition industries from the sustainable farming of insects. Chitin is a high-value bio-polymer with many uses in medicine, cosmetics and as a food additive. Hexafly is also developing novel chitin extraction technologies. 

In the next few years, Hexafly predicts that the exponential increase in demand for fish food will far exceed supply and the industry will not be able to meet this demand due to declining wild fish stocks, stricter fishing quotas and an increase in material costs. Hexafly’s aim is to bring an insect farming revolution to the world and find smart ways to feed the planet.

Coolar
solution: added 21st December, 2018

Coolar UG

Coolar

Coolar has produced an electricity-independent medical refrigerator. The Coolar system uses warm water that is heated through solar energy and stored in a water tank. It does not use any moving parts, hazardous cooling fluids or lubricants. Thus, the Coolar system is a cheap, durable and sustainable solution for storage of vaccines, medicines and food in regions with unreliable or expensive electricity. The Coolar system runs independently from electricity by using solar heat, which makes it almost carbon neutral. Such a refrigerator can enable doctors and health professionals to preserve lifesaving medicine and vaccines in a reliable and eco-friendly way.

Cost-competitive solar heat though optimised lenses
solution: added 21st December, 2018

Heliac

Cost-competitive solar heat though optimised lenses

Heliac’s solar collectors produce utility-scale heat at unsubsidized costs they claim is below that of fossil fuels anywhere in the world. By using inexpensive lenses that work like magnifying glasses and generate temperatures up to 400 °C, Heliac targets process heat markets responsible for 15% of the global demand. These markets include desalination, district heating and cooling, and heat for numerous other standard industrial processes. Heliac believes their solution is scalable enough to meet any potential demand today. Their first 2 MW solar field is in operation in Denmark producing heat for district heating.

Intelligent electric bike trailers
solution: added 21st December, 2018

NÜWIEL

Intelligent electric bike trailers

NÜWIEL has developed and built an electric bicycle trailer that automatically follows the movement of the bicycle. The cyclist does not feel the load of the trailer or the cargo. The trailer, thanks to a special coupling, is mounted in a few seconds under the saddle of the bicycle, without the need for further installations. When used without a bicycle, it can also be used as an electrically powered handcart in pedestrian-only zones and inside buildings. Thanks to NÜWIEL’s modular design, the trailer can be used with different cargo structures. It is possible to install an existing transport box system on the trailer, or to develop a custom box for different needs.

Matter

Sustainable pensions

Matter is a sustainable alternative to a normal pension plan that avoids investments in fossil fuels, weapons and tobacco, while more money is invested in companies working towards a sustainable future. A Matter customer can track their savings through a digital platform and see the impact of those savings. Matter claims that we have invested 4 to 5 times as much money in fossil fuels as we can afford to extract and combust if we are to avoid catastrophic climate changes. A calculator shows a Matter customer how much their savings have contributed in terms of reducing CO₂ emissions and waste production.

Environmental intelligence for healthy cities 
solution: added 21st December, 2018

Green Urban Data

Environmental intelligence for healthy cities 

Green Urban Data produces software that monitors and measures temperature at the neighbourhood level, locating the most vulnerable areas and offering recommendations for action to stabilize the temperature in those areas. Their innovation aims to counteract the effects of temperature on the health and economy of a city, using software as a service (SaaS) to adapt a city to the effects of temperature variations. Possible uses are for the interconnectivity of green urban areas, the design of protocols to act against heat waves, and the planning and design of green infrastructure.

Solar steam for industrial processes
solution: added 21st December, 2018

Solatom

Solar steam for industrial processes

Solatom is a solar concentrator designed for generating high temperature heat (steam, hot water or thermal oil) in industrial processes. Solatom's modules are formed by rows of mirrors that track the sun, reflecting the sunlight on a vacuum tube. The fluid circulating through the tube absorbs the reflected energy producing an increase in the temperature of the fluid (up to 300 °C). Each module has a nominal power of 15 kW thermal. When more capacity is needed, the modules are joined together, increasing the total power of the plant. The system is designed for be deployed on the rooftop, with a specific weight under 23 kg/m².

AI-based platform for smart driving
solution: added 19th February, 2019

Greater Than AB

AI-based platform for smart driving

Greater Than’s platform can reduce fuel consumption and increase driver awareness through driving data analysis. Customers insert an on-board diagnostic module into the USB port of their car. This is synced to the driver’s smart phone and information is fed to the cloud. Based on how the driver performs, Enerfy Driving gives low-risk or high-risk scores. Low-risk drivers are those that drive generating the least amount of environmental impact. The technology processes large amounts of driving data, algorithms performing risk assessment are built on machine learning and generate data in real time.

Optimized tap nozzles saving water
solution: added 20th February, 2019

Altered Stockholm AB

Optimized tap nozzles saving water

Conventional taps allow water to gush out at around 10–12 liters per minute – but only a fraction of that water is actually used for washing hands or rinsing plates. Altered:Nozzle “atomizes” the water, breaking it up into a high speed dense mist made out of millions of individual drops. The speed of the water is also increased up to 50 km/h. This way the user gets in contact with, and uses, every single drop of water coming out of the tap. The result is only 2% of the flow compared to a regular tap. It consists of a simple retro-fit that can be installed in less than a minute in most existing taps in the world today. This design is said to significantly reduce water consumption as well as energy.
