Short description.

Vegetation & Agriculture

Provides solutions for precision farming, enabling farmers to monitor their crops and make better decisions. Their devices and platform can make predictions for irrigation scheduling, fertilizer requirement, pest attack prediction, and plant disease detection.

Their indoor vertical farms grow produce locally within cities with 95% less water, no pesticides, and 100x more productivity on the same footprint of land compared to traditional agriculture.

They plant native trees & vegetation using drone swarms and spray to protect them. Provide valuable insights to customers by collecting data in the field. Work with Governments, nonprofits, and private land owners as a service provider.

Their mission is to reforest the world’s 2 billion hectares of degraded land.

Combined tomato and fish farm grown in a system where fish basin waste water nourishes tomatoes, and the tomato bed in turn cleans the water which goes back to the fish basins. Their fish is grown without antibiotics and the tomates does not need fertilizers.

Produces a commercial scale hydroponic growing system, which is cheaper and easier to install and maintain than traditional hydroponic systems. The goal is to bring the benefits of hydroponics (less water and land, more consistent yields), with a lower investment up front.

Produces Solein - a single-cell protein - from water, CO2 and electricity. It doesn’t require arable land or irrigation and isn’t limited by climate conditions. The original concept of Solein was born from a NASA space programme, and was further developed in the research projects of the Technical Research Centre of Finland Ltd and the Lappeenranta University of Technology (LUT).

Uses satellite imaging to save fertilizer usage up to 30%, and track crops health. This allows farmers to reduce their Nitrous Oxide emissions, a greenhouse gas that is 298 times more potent than CO2.

Food

Created an ingredient named Heura which represents a new generation of plant-based proteins using innovative production techniques to get textures never seen on the vegetal realm. Heura needs 94% less water than to produce the same amount of veal protein and only 0.5kg of soy per kg produced.

Their plant based burgers require 96% less land, 87% less water, and 89% less greenhouse emissions to produce than traditional burgers. Their mission is to produce plant based meat in order to reduce the impact of the meat industry on the environment.

Reduce or avoid meat entirely by finding great vegetarian or vegan food all over the world.

Helps restaurants, cafes, and grocery stores selling their surplus food at a discounted price. As a result, users get food for less and businesses receive an additional revenue stream — all while reducing food waste.

Mobile app for food-sharing, aiming to reduce food waste. It does this by connecting those with surplus food to those who need or wish to consume such food. The food must be edible; it can be raw or cooked, sealed or open.

Gives the possibility for restaurants, stores, bakeries and cafés to sell unsold food at the end of the day. Since it is impossible to know in advance what will be the unsolds of the day, the users get a "surprise basket" of about 500g of food. Pretty much like Karma, but more present in France.

Materials

Offers a biomaterial produced from food and vegetable waste, that can be used for packaging as an alternative to plastic. This material is translucent, resistent, and home compostable.

Offers underwear, essentials and activewear made consciously in Europe. The material used for their production is natural, renewable, recycled, biodegradable and or low-impact textiles only.

Manufacture add-ons to vapor-compression based cooling systems, which reduce their electricity usage while being CO2 neutral themselves.

Water

Developed a system working with a tube with holes placed on the bottom of a river. Pumping air through the tube creates a bubble barrier, or air curtain. The air bubbles force plastics in the water to the surface, making them accessible for removal.

Developed a technology to passively collect ocean debris, with the goal of cleaning the oceans of 90% of their plastic waste by 2040. In 2018 they deployed their solution in the Great Pacific Garbage Patch.

Collaborated with NASA to develop a shower system that uses 90% less water. The shower has a purification system that makes it possible to reuse the same batch of water. The company now wants to make this technology - initially developed for space - available to consumers.

This is an app which lets you find free water refill stations across the UK. Currently there are more than 20,000 free stations across the nation. The app also tracks saved bottles, saved carbon and donates 13p every time you refill a bottle to planet protecting campaings.

Their mission is to reduce plastic in the oceans through a floating rubbish bin that collect pollutants on the water surface. As of October 2019 they have deployed 719 Seabins and are capturing almost 3 tonnes of rubbish per day.

Develops a reverse osmosis technology for producing drinking water with low operating expenses and no CO2 emissions. The desalination system is fully solar, independent of external energy sources and easy-to-use and maintain.

Energy

The UK's biggest green supplier. They provide members with 100% renewable electricity from solar, wind and hydro. Plus, the gas is 100% carbon neutral. 10% is green gas produced from renewable sources like food or farm waste.

Using Direct Air Capture technology, Carbon Engineering aims to take existing CO2 directly out of the air, then use the gas to make carbon neutral synthetic fuels for planes, trucks, and ships. Carbon Engineering is funded by several government and sustainability-focused agencies as well as by private investors, including Bill Gates and oil sands magnate Norman Murray Edwards.

A software company offering access to live and historical data of the origin of electricity and its associated carbon emissions in 90+ countries, based on open-source contributions.

Develops and sells electric scooters and battery swapping infrastructure.

Converts electrical energy to compressed air stored in accumulators under water. Once in the accumulators, the energy can be stored until required by the grid. When the energy is required, the weight of the water pushes the air back to the surface, where it is converted to electricity using a generator.

  • Inspire | Philadelphia, USA | 2014

Simplifying consumer adoption of clean energy by offering an array of affordable clean energy plans to homeowners that integrate with smart home technologies.

An online taxi app like Uber that gives the possibility to use electric cars and partners with the GoodPlanet foundation to fully compensate for the carbon generated by its rides. Since 2019 it is only available in France.

Developing wireless charging for the automotive and transportation industry. Allows any type of vehicle or appliance to be connected to electrical power grid without the use of cables or wires.

Provides solutions for the production, storage and distribution of hydrogen from renewable energy sources.

Non-profit research and development lab, focused on reducing greenhouse gas emissions by solving machine learning problems. As of 2019 they are working on a forecasting system to reduce gas turbines backups on power grids that use solar energy.
