Spinach Can Send Emails Now + Other Fantabulous Eco-Innovations

These 15 innovations are just the kind of news you need. Each doing bold things in remarkably different ways. With some small in stature, but never in scope. From wow factors to believe them when you see them ideas. And yes, if you're wondering, I put the spinach at the bottom of the list. But... I bet you'll stop and stare a few times before you get there.

Innovation of any kind is a guiding light to think on. Reminding us change is possible. That hope matters and conviction's key. So what about evolution, then? If you ask me, it's our entire purpose on this Earth... also inevitable. Which is why innovation makes such great #inspo, I s'pose, but these eco-innovations aren't social fodder for me. They're everyday beacons of hope. And who doesn't want more of that?

I'm also spotlighting these eco-innovations as palette cleansers, if I'm honest. Heart warmers, sure. But mind medicine, in their way. An alternative to doom scrolling... bloom scrolling?

Bottom line, the soil is rich down below. Ready to ripen the imagination with visions of the future happening right now. So uproot yourself from all that out-of-your-hands-hand-wringing. Free yourself from the news cycle of doom and start blooming instead. Make time for hope, for a change...

BIQ Building, Hamburg

Worldwide first facade system that cultivates micro-algae to generate heat and biomass as renewable energy sources.

The BIQ house in Hamburg, Germany, is the world's first apartment for green facades using microalgae. The 15-unit apartment building's facade is wrapped in algae biomass, which cultivate micro-algae to generate heat and biomass as renewable energy sources. Comprising 129 integrated SolarLeaf photo-bioreactors that absorb CO2 emissions while converting natural light into biomass and heat. They can also be used as adaptive shading devices.

The SolarLeaf system was developed collaboratively by Strategic Science Consult of Germany (SSC), Colt International, and Arup. The biomass and heat generated by the facade are transported by a closed-loop system to the building's energy management center, where the biomass is harvested through floatation and the heat by a heat exchanger. Because the system is fully integrated with the building services, the excess heat from the facade can be used to heat the building, too.

Nature Squared Eggshell Tiles

British-Chinese textile designer Elaine Yan Ling Ng has created a sustainable composite made from discarded eggshells for Nature Squared, shaping the CArrelé handmade collection of speckled wall tiles.

The eggshell fragments used in Elaine's tiles are a by-product of bakeries. The tiles are produced in Nature Squared's factory in Cebu, Philippines, where 3,000 organic white eggshells from local bakeries and kitchens are crushed, combined with a binding agent, and cured at room temperature to create a square meter of tile.

Eggshells are strong, naturally UV-resistant, and absorb natural colors in fascinating ways. The eggshells are cleaned and crushed into different sizes, from sand to 3mm fragments, and natural dyes are added to achieve natural tones before the composite is set. The collection's name, CArrelé, combines "CA," the chemical symbol for calcium, referencing the calcium carbonate in eggshells, with the French word for tile...

This is the first time eggshell waste has been made into a commercial product. And what a start! The CArrelé tiles are safe, durable, naturally UV-resistant, easy to clean, and available in 5-millimeter slabs.

ForestBank™️

ForestBank™️ is a material design created by Studio Yumakano that aggregates materials from the forest typically deemed worthless for construction or furniture making.

Rather than simply creating lumber, ForestBank™️ performs experiments and develops materials that realize the desire to find the various value in whole forests. Their unique material is made from small trees, foliage, bark, seeds, soil, and other small forestry debris that are mixed with a reactive mineral base. The material can be shaped with ordinary woodworking methods and applied in various ways through furniture and interior design.

The ForestBank™️ material reveals intriguing patterns that vary dramatically depending on the angle and depth of a designer's vision. The leaves from different seasons, earth from the forest floor, roots, and seeds all come together to form complex patterns and cross-sections that typically go unseen. Creating variety that is as complex and fascinating as any wood grain.

ForestBank™️ can be made not only from forest debris but also from waste pruned from trees lining streets, in parks and gardens, and from wood scrap from woodworking studios. The characteristic yellows and greens are the actual coloring of the trees, which are dyed by bacteria found in nature. And so just by looking at the ubiquitous nature of wood from a different angle, a whole new material has been unearthed...

Mechanical Trees

The world's first mechanical tree designed to capture carbon dioxide (CO2) from the atmosphere has been installed at Arizona State University (ASU).

Developed by Professor Klaus Lackner, the mechanical tree is 1,000 times more efficient at removing CO2 from the atmosphere than a regular tree. The tree is based on direct air capture (DAC) technology and is commercialized by Carbon Collect Inc.

The mechanical tree resembles a giant stack of vinyl records and contains absorbent tiles that soak up CO2 carried into the machine by the wind. Every 30-60 minutes, the circular discs inside the tree fill up with air, separating CO2 and storing it away for reuse in various applications, such as adding fizz to soda or making concrete.

Lackner and his team at ASU's Center for Negative Carbon Emissions are planning three farms that could soak up 1,000 tons of CO2 per day, with the first of these farms set to open for business soon. According to Lackner's research, mechanical trees could become as common as cars within the next two decades.

AuREUS

AuREUS is an innovative material made from plants, fruit, and crop waste that converts UV light into energy.

Invented by Carvey Ehren Maigue from Mapua University in Manila, the Philippines, the material can be attached to pre-existing structures to generate clean, renewable electricity.

The process of converting UV light into energy involves two stages: first, the UV light is converted into visible light through the crop waste's organic particles when it hits the surface; then, the visible light is converted into electricity by a solar film. AuREUS can produce energy even when not directly facing the sun, making it a more adaptable energy source for people living in temperate and mountainous areas.

The plant waste used to create AuREUS panels is sourced from local farmers affected by climate change-induced weather disruptions. The material is durable, translucent, and moldable, making it suitable for various applications. AuREUS System Technology conserves space by using pre-existing structures, utilizing current resources and waste streams, and supporting local agricultural communities by upcycling crops that would otherwise be considered waste.

In a prototype demonstration, a single 3-by-2-foot lime green-tinted panel installed in a window generated enough electricity to charge two phones per day. When scaled up, AuREUS has the potential to empower off-the-grid energy sourcing, build more efficient solar fields, and enable self-sufficient energy sourcing.

Living Tree Bridges

The Khasi tribe in Northeast India has been weaving together tree roots for centuries to create living root bridges. Forming essential passageways for rural connectivity in the region.

These living tree bridges are made from the roots of rubber trees (Ficus elastica) and are found in areas such as the East Khasi Hills of Meghalaya, particularly in and around the villages of Tynrong, Mynteng, Nongriat, Nongthymmai, and others.

The construction process involves planting tree trunks on each side of a riverbank to create a sturdy foundation. Over the course of 15 to 30 years, the Khasi people slowly thread the rubber tree roots across temporary bamboo scaffolding to connect the gap. The combination of humidity and foot traffic helps compact the soil over time, allowing the tangle of roots to grow thick and strong. Mature bridges can stretch from 15 to 250 feet over deep rivers and gorges and can bear impressive loads, supporting upwards of 35 people at a time.

The double-decker root bridge in Cheerapunji is one of the main attractions in Meghalaya, and the growing tourism in the region supports the local economy. The exact origin of the living root bridge tradition in this region is unknown, but the earliest written record of these bridges in Cherrapunji dates back to 1844.

The humid climate in the Nongriat village in Northeast India is ideal for making these pathways grow, and many of the living root bridges are still used daily. These bridges not only stand the test of time but also contribute positively to the ecosystem, showcasing the ingenuity of the indigenous tribes of India.

The Bee Brick®

The Bee Brick® is an innovative solitary bee house designed to provide a nesting site for red mason and leafcutter bees, among other cavity-nesting species.

Created by Cornwall, UK-based company Green&Blue, the Bee Brick® can be used in place of a standard brick or block in construction or as a standalone bee house in your garden.

Solitary bees are non-aggressive and safe around kids and pets, as they have no queen or honey to protect. The Bee Brick® contains cavities where bees lay their eggs before sealing the entrance with mud or chewed-up vegetation. The offspring emerge the following spring and the cycle begins again.

To install a Bee Brick®, place it in a warm sunny spot on a south-facing wall at a minimum height of 1 meter, with no vegetation obstructing the holes. It is highly recommended to have bee-friendly plants nearby, such as lavender, honeysuckle, and buddleia, to provide food for the bees.

The Bee Brick® is just one piece of the puzzle regarding our changing biodiversity needs, alongside bee-friendly planting, more wild spaces and more rewilding, of course.

Lovely Trash Project

The Lovely Trash project, created by Blast Studio, aims to transform everyday waste into sustainable design by using natural ecosystems as inspiration.

The Lovely Trash project involves collecting coffee cup waste directly from coffee shops around London and transforming it into furniture using mushrooms.

Blast Studio has successfully raised funds for the Lovely Trash project through a Kickstarter campaign, where they showcased vases grown with fungi on coffee cup waste. The process starts by shredding the collected coffee cups and making a paste infused with mycelium, the root system of mushrooms. The mycelium helps break down the waste and binds it together, creating a sustainable material that can be used to create furniture and other design items.

Plastic-eating Caterpillars

Plastic-eating caterpillars, specifically the larvae of the wax moth (Galleria mellonella), could help combat plastic pollution.

Researchers at Cambridge University discovered that these caterpillars can chew through plastic, degrading the chemical bonds in a similar way to their wax-eating process. The caterpillars can create holes in plastic bags in under an hour.

Scientists from Brandon University found that the caterpillars can survive on a diet of solely polyethylene, a type of plastic used in shopping bags and food containers, for over a year. The caterpillars have a close working relationship with their gut microbes, which also consume plastic. When the caterpillars and their gut microbes work together, the plastic biodegradation process is accelerated.

Researchers hope to use this knowledge to reduce plastic waste, which enters waterways and harms marine life and their habitats. They aim to understand the chemicals that allow the caterpillar to decompose the material and potentially develop a technical solution for minimizing plastic waste.

Spinach Sending Emails

Scientists at the Massachusetts Institute of Technology (MIT) have engineered spinach plants that can detect nanoparticles of all kinds of things in soil and then relay that information back via email... for real, though.

The roots of these engineered spinach plants detect the presence of nitroaromatics in groundwater, a compound usually found in explosives such as landmines. The carbon nanotubes in the plant leaves emit a signal when they sense these compounds, which is picked up by an infrared camera and sent back to a lab via email.

The plants' complex and sensitive root systems make them incredibly good at detecting changes in soil. Which means this technology could be invaluable to farmers, because the plants can sample water content in the soil and the presence of nutrients better than any man-made device. If scaled up, it could help warn humans of climate change, pollution, and incoming droughts.
