A sustainable composite lumber made from waste materials

Spotted: Imagine the ability to transform millions of tonnes of rubbish into useful materials, without any onerous sorting and cleaning processes. Waste technology company Ecogensus’ patented waste-derived lumber does just that. Using unsorted household waste, including organic material, the company’s Dynamic Organic Repolymerization (DOR) process creates sustainable, composite lumber strong enough to replace traditional building wood. 

Called EGS-6, the composite lumber is structurally reinforced, and the company is continually researching ways to increase the material’s strength and load-bearing ability. As well as building materials, Ecogensus provides a suite of additional waste management solutions.  

Introduced in 2023, the Rhino Recycling facility is a distributed hardware system that processes municipal solid waste. Available in a range of sizes, from 300 to 5,000 litres, the recycling facility handles everything from wastewater sludge to organic food waste and unsorted solids.   

As well as industrial recycling, Ecogensus also provides recycling as a service with its WeRecycle modules. The modules help upgrade current processing facilities and can work directly next to landfill sites for continuous energy and material production. A platform for monitoring sustainability goals and waste management, along with bioenergy fuel and home décor and furniture lines, are also part of Ecogensus’ broad range of products and services that help put municipal solid waste to good use.  

From artificial intelligence (AI) food waste management to river waste collection, Springwise has spotted a variety of examples of innovations in the archive seeking to find alternative uses for rubbish.

Let Us Count the Ways We Love Induction

How we cook our food plays a key role in our ability to decarbonize our lives and keep our families healthy. Compared to activities like transportation and space heating, cooking can be modest in its emissions. It’s also one of the last holdouts in the transition to an all-electric, zero carbon home. Fortunately, there are lots of reasons why induction cooking is better than gas: control, speed, safety, health, and the environment. Let’s also look at some things to consider when buying an induction range for your home.

Induction ranges can eliminate the need for gas piped to your home, which is a game changer. Gas stoves have long been the gateway drug that fossil fuel companies use to get inside homes in the first place. Few people care about what fuel heats their water or air, but many home chefs have an emotional attachment to cooking with gas: its ability to adjust temperature quickly and the cozy blue flames that hearken back to humans’ prehistoric love of fire.

Old-school electric-resistance coils take forever to heat up and cool down, making temperature control difficult. Induction technology, however, creates an electromagnetic field that generates heat via the iron in pans. Rather than heating the space under a pan, like a traditional range, the heat emanates from the pan itself. (Here’s more info about the science for those who want to geek out.)

Like many efficient, clean energy technologies, the history of induction cooking goes back 100 years. But induction cooking’s moment has arrived. Currently, only 3% of homes in the US have induction (but the market has grown more than 40% in the past two years), and 70% of homeowners say they would consider induction for their next stove.

Types of Induction Cooktops

The easiest way to try out induction is with a portable cooktop, also known as a hob. This countertop appliance has one or two burners and plugs into a standard outlet. These are great because they 1. let you try induction for only $60 to $200; 2. are small and portable, allowing anyone (including renters) to use them; 3. serve as a supplemental cooktop when your main range is full; and 4. support resilience. (Our friend, Brian Stewart from Electrify Now, uses his with a portable battery when camping or when the power goes out.) Check out these Epicurious reviews for the best models.

An installed induction cooktop has four or five hobs and sits in a countertop without an oven beneath. If your kitchen design currently has a gas or electric-resistance cooktop, then this will be the easiest swap-out. There are many cooktop options at multiple price points. The Yale Appliances Buying Guide gives a comprehensive list of current models.

An induction range is the full package, with a cooktop and electric-resistance oven, usually convection. It comes in three varieties: 1. freestanding, with knobs and controls at the back; 2. front control, with finished sides and controls on the front; and 3. slide-in, with front controls and unfinished sides, so they work best between cabinets.

Seven Reasons to Love Induction

Our family has been cooking with induction for the past five years. We see many pros, and only one con, when it comes to this technology that is undoubtedly the future of cooking.

Environmental

For us, transitioning to induction means that our cooking fuel comes from clean, renewable sources. Induction is slightly (5–10%) more efficient than electric coils and much more efficient (300%) than gas, according to ENERGY STAR. Because cooking accounts for only 4–5% of energy use in the home, you’ll see only modest carbon reductions by switching to induction.

Burning “natural” gas emits multiple greenhouse gases, including methane, an even more powerful greenhouse gas than carbon. A recent study found that 75% of unburned gas leakage occurs when the stove is off. Induction allows you to remove gas from your home, decarbonizing without sacrifice.

Health

We’ve likely  all heard the accumulating body of research showing that gas is a a major source of indoor air pollution posing a health hazard. Cooking with gas releases toxins like nitrogen oxides, particulate matter, and carbon monoxide—all of which can exacerbate asthma and cardiovascular disease. One Rocky Mountain Institute (RMI) researcher commented that, “For children who live in a home with a gas stove, the increased risk of asthma is on par with living in a home with a smoker.” While there are no regulations for a home’s indoor air quality, the RMI study found that some gas stoves emit indoor NO2 at levels above the outdoor standards.

Safety

In a related home-safety benefit, induction only heats the pans and pots and not the space around them, reducing cooktop temperatures and almost eliminating the possibility that anyone will get burned. Induction “burners” also turn off automatically after 10 seconds when they don’t detect a pan, and they cool down much faster after use. Our three-year-old can help stir hot pots and pans on our induction stove (as long as the contents aren’t boiling), and there is no risk of her burning herself on live flames. If she drops a towel on the stove while cooking, or even touches a burner, it’s no big deal.

Control

Induction stovetops exceed gas ranges’ performance in their ability to quickly change and control heat. There is no lag time with induction cooking like there is with electric resistance. Lowering your heat setting will almost instantly reduce your sauce from a rapid boil to a slow simmer. Induction also offers excellent low heat settings that gas burners typically struggle with.

Speed

You can boil six cups of water in two minutes. (Mic drop.) Because induction stoves are twice as fast as gas or old electric coils, boiling a large pot of water for a quick pasta dinner is actually quick. When first switching to induction, you might be surprised by how much more quickly your food cooks. Watch out!

Cleaning

The solid surface of an induction range means you can clean it with the swipe of a sponge. This is vastly superior to the time and effort it takes to remove and clean the parts of a gas or electric coil range. Plus, the smooth surface serves as an additional kitchen prep surface when it’s not cooking.

Future Proofing

As of this writing, more than 100 cities around the country (including New York City) have banned gas in new buildings, with some of those laws including a phaseout strategy for existing buildings. Go ahead and embrace the induction future before you have to.

You get really used to them

The one (and only) con for us is that our stove model has a bit of a learning curve. The button plus slider interface is not as intuitive as knobs (which is why many newer induction models are moving to knobs). While we quickly learned the technique, when we Airbnb our house, or have a new babysitter, we need to run through basic instructions. The advantages to the touch-and-slide controls are  that they rarely break and are more precise than dials, according to Yale Appliances. A stove with touch controls may beep and/or turn off when something—spilled liquid, a spoon, or potholder—touches the control panel. This protects the controls but can be annoying.

Last year at Thanksgiving, we rented an Airbnb with a gas stove and did a lot of holiday cooking. After not using gas for several years, the difference was striking! We could feel the particulate matter in the air infiltrating our eyes and lungs. The flames blew every which way, making us hot, and we had to remind the kids to stay back. One time a burner didn’t ignite, and we had to wait for the smell of gas to dissipate before lighting a match to make it catch. It felt crazy! How is this form of cooking still legal in our homes?

It’s time to add induction stoves to your list of home improvement priorities, so you can look forward to the improved cooking experience, safety, and human health benefits in your future. Here’s a few things you need to consider when buying induction for your home.

The transition to induction means that most of the 47 million homes that currently cook with gas will have to upgrade an electrical outlet. Most gas ranges (unless they are dual-fuel where the oven is electric) plug into a standard 120V outlet, while most induction cooking (except portable) requires a 240V wire with a 50A circuit. If you currently use an old-school electric cooktop, you may still want to upgrade the outlet. When we purchased our induction stove, the install was fairly easy. We already had a 220V outlet, but it was the older version, without grounding, rather than the modern four-prong one.

Some estimates for running a new wire and outlet for an induction stove can run as high as $3,000. Though, in our experience working with a trusted handyman, it was only about $300. Carbon Switch surveyed 90 people who switched to induction and found the average price for electrical work was $987.

Because induction works by magnetic force, it requires pots and pans made of magnetic stainless steel, cast iron, enameled iron, and nickel. Aluminum and some copper pans won’t work. High-end brands usually work, and there are also now many more affordable options. You can check your pots and pans for compatibility simply by grabbing a fridge magnet and seeing if it sticks.

Hoods that vent outdoors are important for all cooking. Even though induction and electric cooktops don’t produce NOx or CO pollution like gas stoves, any cooking, especially at high heat, produces particulate matter that needs to be vented. (This includes cooking on the portable induction hobs.) But ventilation is easier with induction because the stoves produce less ambient heat and far fewer emissions.

Induction stoves put you on the path to superior, clean cooking and are a core technology in the decarbonized life. Fortunately, Consumer Reports has reported on a recent price decline in induction stoves, with many models now selling for about $1000.

 

For low- and medium-income households, the new Inflation Reduction Act offers rebates of up to $840 to purchase an induction stove. These low-income rebates are expected to roll out later this year. We couldn’t find many local utility rebates, but there are a couple, like this $750 one in the Bay Area.

AI-powered leak detection reduces water waste

Spotted: Managing water well is increasingly important as the world is impacted by climate change. Yet water in buildings is unmanaged – delivered through unintelligent pipes that are unnecessarily costly and inefficient. The average household can lose 10,000 gallons of water every year due to leaks, and when a pipe breaks or leaks, escaping water can cause severe damage. With the help of artificial intelligence (AI), Israeli company Wint has found a way to change this: using intelligent pipes to detect water leaks and wastage. 

Using real-time AI, Wint’s breakthrough technology prevents water waste at the source. When there is a break or leak, the devices alert maintenance staff and can even automatically shut off water supplies when needed. Unlike other solutions, the AI system is constantly learning and adapting to different water networks, supporting systems from domestic water to air conditioning and heating to ensure the buildings can effectively manage the water throughout. 

Yaron Dycian, Wint’s Chief Product and Strategy Officer explains: “The built environment is one of the largest industries in the world sized at many trillions of dollars; it includes all construction sites, residential buildings, commercial buildings, etc… Yet this vast ecosystem is also one of the least technologically advanced one. Having built solutions for the most advanced users of IT technologies such as banks and e-commerce, I decided that it would make sense to help bring the benefits of IT to this relatively less IT-savvy world. Seeing the growing need for sustainability combined with the insurance impact of water leak damage, this seemed like an obvious area to address.” 

Recently, the company completed a funding round, raising $35 million (around €32.4 million) to drive growth for managing water through AI. 

Springwise has previously spotted other intelligent innovations in the archive tackling water scarcity through management, from an AI used to manage global water supplies to a data-driven water management system that ensures communities have enough fresh water.

Building-level flood alerts for insurers and property owners

Spotted: Floods are among the costliest and most destructive of natural disasters. And as climate change picks up pace, flooding, including urban flooding, is expected to increase dramatically. Fluctuating weather patterns also mean that many floods are missed by conventional weather forecasting techniques.

To help insurers and building owners, Loughborough University spin-out Previsico has developed a real-time forecasting technology that models flooding at a granular level. The company’s models are updated every three hours using a combination of rainfall nowcasts and forecasts.

Using high-quality topographic and hydrological data, the company’s flood simulation software produces fast and accurate representations of how water will flow across flood plains.

The platform also supports the delivery of email warnings and offers a flood dashboard to enable users to visualise how a flood situation evolves over time. Flood forecasts can even be integrated into existing warning systems. 

Previsico’s modelling is aimed at helping governments, aid agencies, commercial property owners, and insurance companies by providing them with actionable information. For insurance companies, the technology helps to mitigate claims costs, supports customers, and improves underwriting performance. 

Other flooding innovations spotted by Springwise include low-cost sensors for real-time monitoring of coastal flooding. Other insurance innovations include insurance payouts based on weather data, and a platform that lets financial institutions forecast climate risk.

Boosting science research with day-to-day spending

Spotted: As the world continues to emerge from the COVID-19 pandemic, spending on the sciences is again a hot topic as governments work to decide which areas of research to fund and with how much money. In the UK, the government has announced almost £3.5 billion for use in developing supercomputing capabilities, regional innovation accelerators, and workforce skills for the next generation of jobs.

For citizens interested in science, a new bank card offers a way to get involved in the latest research. Called the Science Card, the current account and Mastercard debit card allows members to round-up everyday expenditure to support research projects.

There are two levels of membership available. The Standard account is free, while the premium ‘Fusion’ account costs £19.90 per month. The company is currently working on a new perk for Fusion account holders – the ability to become partial owners of the intellectual property (IP) of a new project. Depending on the commercial success of a project, IP owners could earn passive income for an extended period of time.

Cardholders use the app to explore available research projects and choose which ones to support, either with a direct payment or via micro-grants from rounding up common expenses. The company itself dedicates 10 per cent of its profits to scientific research. Cardholders also receive more conventional benefits such as immersive spending data, and the company plans to offer cashback on certain sales, including books, coffee, and software.

Other positive impact cards spotted by Springwise include a card that provides cashback on environmentally friendly products, a debit card that lets users fund tree-planting as they spend, and a card that powers the circular economy.

Recycling e-waste with microbes  – Springwise

Recycling e-waste with microbes  – Springwise

Spotted: According to Statista, more than 50 million metric tonnes of e-waste are generated every year. And as the world becomes increasingly digitised and reliant on technology, this is only set to increase. Often, this e-waste ends up in developing countries, where electronics are burned on a mass scale to reveal precious metals, releasing extremely harmful toxic gases. 

But now, New Zealand company Mint Innovation has devised an eco-friendly multi-step process for breaking down e-waste. The technology uses low-cost and low-impact biorefineries that extract valuable metals from scrap circuit boards so they may be reused, reducing future need for mined materials. 

First, electronic circuit boards are ground up. If metals can’t be retrieved using electrochemistry, Mint dissolves the precious metals using its proprietary green chemistry – chemistry that either reduces or completely eliminates the use or “generation of hazardous substances”.  

The company then recovers metals from the solution with a bioabsorption process, whereby special microbes added to the solution absorb the metals. A centrifuge separates metals from the microbes and these extracted materials are then refined into pure metals, ready to be repurposed and resold as items like jewellery or new electronics.  

Although Mint has been focused on recycling electronic devices and scrap circuit boards so far, the technology could also be used in the recycling of batteries and catalysts on a large scale. 

Other e-waste innovations spotted by Springwise include clean e-waste recycling and mineral processing, the world’s first fully recyclable computer chip substrate, and a project where gamers can return their e-waste for Minecraft coins.

Rare-earth-free generators for wind and tidal power

Rare-earth-free generators for wind and tidal power

Spotted: The scarcity of rare earth elements (REE) is a challenge for the wind and tidal renewable energy sector. These minerals are lanthanides (Lanthanum-Lutetium in the periodic table plus Yttrium and Scandium) and are vital in the conventional production of wind and tidal turbines, specifically in the magnetic cores of these generators. Contrary to their name, they are not rare in the Earth’s crust, but they are rarely found in high concentrations, which makes mining them difficult. And even after being mined, it is necessary to refine them. China currently has a near monopoly in the global trade of these materials, with 90 per cent of all the REE entering the market produced in the country. The EU, meanwhile, has to import almost all of its REE.

This is where UK company GreenSpur comes in. Its generator replaces the need for REE in the magnets of wind and tidal turbines. The company uses far more abundant and easily available ferrite (Iron derived) magnets, and surrounds these with aluminium coils rather than conventional copper ones. The company is able to make these sustainable material substitutions due to a design innovation in the generator itself.

Conventional generators use moving magnets placed around static coils of wire arranged in concentric circles. The movement of the magnets (in this case via wind or tidal energy) produces an electric charge or energy in these wire coils.

The GreenSpur design, by contrast, relies on ‘axial architecture,’ in which disks of aluminium coil are stacked on top of disks of ferrite magnets. This means that the magnetic field flows parallel to the axis of the generator, which results in a higher ‘magnetic flux’ (essentially magnetic strength) and allows for the alternative materials to be used.

The benefits of using these REE alternatives are clear: lower cost of materials, cheaper cooling than conventional REE generators, and greater strength in supply chains for materials. The new design is also more environmentally friendly as harmful REE byproducts are no longer mass produced and low-risk alternatives are used in their place.

Springwise has also spotted hi-tech anodes for the next generation of batteries as well as one company that uses shades screens as a renewable source of energy.

Round-the-clock electricity-free cooling – Springwise

Round-the-clock electricity-free cooling – Springwise

Spotted: As the world heats up, there is a rapidly increasing demand for more cooling technologies. However, nearly 20 per cent of the electricity used in buildings around the world is already going to air conditioners and fans, with cooling accounting for around 7 per cent of global greenhouse gas emissions. What is needed is more efficient cooling technologies, and this is exactly what US startup SkyCool hopes to deliver.

SkyCool grew out of research in the lab of Aaswath Raman at the University of Pennsylvania. The technology is based on infrared radiation and could improve the efficiency of cooling systems. All objects give off heat in the form of infrared radiation, and this heat is then trapped by the atmosphere. However, radiation given off in wavelengths of between 8 and 13 micrometres is able to escape into space. Raman and his team have developed a proprietary material that converts the infrared light leaving a surface into this wavelength range, allowing the heat to escape into space and cooling the object in the process.

The company’s technology can be applied in several ways. First, the company has developed a system of cooling panels, covered in SkyCool’s dual-mode film, that can improve any air conditioning or refrigeration system. The panels reflect sunlight and emit infrared radiation to the cold sky. Together these mechanisms keep the panels, and cooling fluid pumped through them, up to 15 degrees Fahrenheit below the ambient temperature with zero electrical input. As an add-on to an existing cooling system, SkyCool’s panels can improve efficiency by 10 to 40 per cent. And, in some situations, the panels can replace existing cooling systems altogether, in which case energy savings can reach up to 90 per cent.

The company’s optical film can also be used in other applications separate from the panels. For example, it can be applied to batteries, outdoor shade structures, metal roofs, or refrigerated vehicles, bringing the benefits of solar reflectivity and infrared radiation to these surfaces.

SkyCool has recently completed a $5 million Seed funding round, which will allow the company to move from the commercial-scale pilots to scaled deployments of its panel and film products. The company is focusing on deploying panels in commercial premises such as grocery stores, refrigerated warehouses, data centres, and similar buildings that require consistent cooling.

Cooling cities and other areas more efficiently is becoming a vital component to achieving net zero. Other innovations that are addressing this issue include insulation made from sheep wool and paint that passively cools buildings.

Safe and natural baby hygiene products for the African market
CategoriesSustainable News

Safe and natural baby hygiene products for the African market

Spotted: Many of the care products currently on the market in African countries are of Western origin, created by Western experts, and based on Western tastes. Nigerian baby and child healthcare company Mobaby Care is working to change this with a line of all-natural skin and hair care solutions designed for babies and children.

Mobaby was started by Nigerian scientist and entrepreneur Maryam Adebola-Salami, who was inspired after using a synthetic oil that burnt her child’s skin. She decided to create products that use only all-natural, local, oil- and herb-based formulations, that are specially designed for African skin. The products are also manufactured for African needs, for example, many of the products contain natural mosquito repellents and protection from UV rays.

Mobaby argues that health and the gender gap are interrelated issues, and the company also keeps this larger picture in mind. Accordingly, 60 per cent of its suppliers and 50 per cent of its partners are female-led, and 80 per cent of Mobaby’s staff are female. The company’s focus is on helping women maintain their health and the health of their family, but also on education and providing much-needed jobs.

This year, the company partnered with Access Bank, through its Project Uwar campaign, to distribute 3000 birthing kits across communities in northern Nigeria. The kits are designed to aid in safe delivery and promote breastfeeding. Mobaby is also working on a project to match mothers with healthcare professionals, as well as an artificial intelligence (AI) platform that can help answer parents’ questions about their children’s skincare and hygiene.

More and more companies are realising that one product does not fit all when it comes to health and beauty. Some of the innovations Springwise has spotted in the archive include an online marketplace that combats fake medicines in Africa and a portable, handheld disease testing kit.

On-demand data makes recycling easy

On-demand data makes recycling easy

Spotted: Despite all of the interest in achieving net zero and reducing waste, recycling rates in the US actually decreased between 2018 and 2021. One of the reasons for this is that regulations vary from state to state, leaving many people confused about exactly what can and can’t be recycled. Faced with this problem, two female engineers at the University of Georgia came up with a solution – a platform that provides users with real-time and location-specific answers to the question ‘can I recycle this?’ 

The platform, dubbed CIRT, provides customers and businesses with on-demand and location-specific data on whether materials can be recycled, composted, or must be thrown to landfill. The company remains in contact with waste management facilities to ensure the information is as accurate and up-to-date as possible. 

The company provides all this information to partnering brands via an API, so that they can optimise procurement and make more sustainable choices on materials. This, in turn, enables them to track and meet ESG goals. 

For customers, information is provided through an app. Brands can also add scannable CIRT QR codes to their packaging, which send customers directly to relevant information on how to dispose of the specific product where they are. And, as a further behavioural nudge, CIRT integrates recycling reminders with regular order updates.

In the archive, Springwise has spotted other innovations making recycling easier, including chemical recycling for unsorted plastics and an inclusive scheme in South Africa.
