ChangeNOW: 7 solutions for the planet to discover during the Paris event

A few steps from the Eiffel Tower, the ChangeNOW salon has taken over the Grand Palais Éphémère for three days of conferences, exhibitions, workshops and meetings around the planet (March 25 to 27).

Around five large stages where experts, activists and other “actors of change” speak in turns according to a program as dense as it is fascinating, there are also the stands of some 300 exhibitors, organized into thematic poles (biodiversity, circular economy, fashion). , cities, ocean and water, food and agriculture, etc.). Focus on seven of the most promising solutions.

Beeodiversity, bees as a source of environmental information.

Biodiversity helps industrial actors or public authorities measure their impact on the local environment. This Belgian company uses bees for biomonitoring. The principle is to collect pollen to study it in the laboratory. This material, transported by feeding insects, makes it possible to reveal the presence of industrial or agricultural contaminants, as well as plant species, in the surroundings of a bee hotel. The registration period is carried out over three years to be able to carry out actions based on the observed measurements.

Morfo: drones over the forest

Restore healthy forests? This is the bet of Morfo, a company whose offices are located in Brazil (Rio de Janeiro), Europe (Paris) and Africa (Libreville). A first type of drone flies over a forest to carry out a diagnosis. After a planning phase, another type of drone comes into play: it will distribute precious capsules that each contain one or more seeds of native plant species, as well as the nutrients they will need to grow, but also strains of microorganisms specially chosen to revive the earth. While others plant trees as they please without worrying about their survival, Morfo, on the other hand, promises monitoring over a period of 5 to 30 years, with the help of drones, of course! To date, around 600 hectares of forest have already been restored in Brazil, Gabon and French Guiana.

AW-Energy, taking advantage of the infinite energy of marine movements

AW-Energy does not ride the wave, but transforms its driving energy into electricity. This Finnish company has developed the WaveRoller (literally wave roller). It is a huge shovel that will be installed at the bottom of the sea, between 8 and 20 meters below the surface. At this depth, the waves no longer move in a roll shape but adopt a mainly horizontal movement. It is this movement that the WaveRoller captures. By tilting back and forth, the facility transforms wave energy into electrical energy and redistributes it directly to the land-based electrical grid.

Demetair, a highly resilient green roof

Who has not already looked with dismay at the so-called “green roof”, burned during the first summer after its installation? And with good reason: weighing around a ton per square meter and 90% mineral, these green covers rarely exceed seven centimeters thick. Suffice it to say that the little water retained is barely enough to keep some poor sedums (succulent plants) alive… Opposing this approach is that of Demetair, a company based in Toulouse and active throughout France, which gives it back its place. to local plants, obtaining, with 98% organic matter, a light vegetal cover (40 kg/m3) and at least 20 cm thick. Thus, 143 liters of water are stored in one cubic meter of roof. Another advantage: it can be installed even on sloping roofs.

Toopi Organics, from urine to agricultural biostimulants

At first, Toopi Organics simply wanted to save drinking water. So the idea was to stop flushing the toilet. To do this, the company has partnered with urine collectors using waterless urinals. But the company then sought to profit from this urine by growing bacteria in it. Thus, in addition to saving drinking water, Toopi Organics seeks to help farmers separate themselves from pesticides by providing them with biostimulants as an alternative. According to the company, switching to Toopi Organics biostimulants could sustainably replace chemical pesticides.

Linen, a green fiber

Imagine a plant that depends on rainwater (zero irrigation) and soil nutrients (low input), while offering an immense “field” of possibilities for fashion? Cultivated in a coastal strip that extends from Caen to Amsterdam (Europe represents three quarters of world production), linen concentrates at least as many environmental benefits as it has advantages for weaving the fashion of tomorrow, since its power of thermoregulation (cool in summer, warm in winter) to the creative possibilities it offers – warp/weft architectures, mixes with alpaca, etc. – through the know-how that surrounds it, the result of millennia of history. If the linen shirt remains timeless, the European Linen and Hemp Alliance shows us that its wardrobe is much richer than it seems. And the plant is also preparing to enter new markets…

Space4Good, preventing deforestation from space

Space4Good tries to put geospatial data at the service of sustainable development actors. For now, the main activity of the company, based in The Hague, Netherlands, is scanning satellite images to detect areas of deforestation. An investigation then follows with local authorities to determine whether the identified facts relate to legal activity or not. Space4Good wants to be proactive in detecting deforestation by creating a prediction system powered by artificial intelligence.

And many other solutions for the planet to discover on ChangeNOW such as Climate Café, Bôndy Madagascar, Project Seagrass, Helios, NoWaterNoUs…

ChangeNOW 2024 will take place from Monday, March 25 to Wednesday, March 27, 2024 at the Grand Palais Éphémère in Paris. Online ticket sales at changenow.world/es/.
