It was Koichi Takahashi's dream to create a sustainable society through recycling and regeneration. His dream came true when he built a company that turns food waste into high-quality pig feed. In his company, Japan Food Ecology Center, Takahashi made use of the popular Japanese practice, "fermentation".
Artificial intelligence (AI) consumes a significant amount of energy, especially deep learning models, and in a few years it is expected that energy use will double. This energy consumption is due to the increasing demand for AI across various industries, which contributes to carbon emissions.
Hidden on the north coast of California is a stand of very unusual redwood trees. Salty winds off the ocean break the trunks, but the trees keep on growing. New branches grow straight up from the broken trunk. Since the trunk is tipped over on its side, the tree ends up looking like a candelabra. After generations of this cycle, the trees have become twisted into fantastical shapes.
The Amsterdam company Respyre has developed concrete and plaster that support the growth of moss. These materials can be used for new construction, as well as on existing buildings. The moss then acts as a respiration system for the city. It takes in water and CO2 from the air and releases oxygen.
Moss has other benefits, too. Watch this short video to find out more.
The standard measure of economic performance, the gross domestic product (GDP), measures the value of goods and services produced within a country over a given period. However, the GDP doesn’t measure social factors like income inequality, domestic violence, drug addiction, or the impact of today’s actions on future generations. It also ignores sustainability and environmental destruction. It’s a very short-term view of market factors without respect to what’s happening on the social and environmental levels.
People throw away more than 80 billion pairs of chopsticks every year. Most of them have only been used once, like the cheap wooden ones you get in restaurants. All of those chopsticks end up in landfills. In China, environmental activists have documented rates of over 100 acres of deforestation every day to keep up with demand.
Floating solar farms, also known as "floatovoltaics," are an efficient way to collect solar energy. They have a number of advantages over land-based systems:
People generally think of trees as disconnected loners, competing for water, nutrients, and sunlight, with winners shading out losers and sucking them dry. But evidence to the contrary is coming to light. Forest trees are, in fact, cooperative and live in interdependent relationships maintained by communication and collective intelligence similar to an insect colony.
In late April, the Indonesian government announced a temporary ban on exports of crude palm oil and its refined products, such as cooking oil. The decision came as a surprise to commercial goods traders as the government had previously stated the ban would only apply to refined products. After the government’s initial statement, prices of crude palm oil significantly fluctuated given uncertainties about what products the ban would cover. Prices have again skyrocketed in light of the most recent announcement.
Indigenous communities in Oaxaca, Mexico, have been working to restore the soil and forests, with remarkable success. Twenty-five communities have restored 49,000 acres (20,000 hectares) over the past 20 years. Restoration efforts are driven by the communities themselves, who together make up the Chocho-Mixtecas Community Alliance.
In 1991, researchers at Berkeley Lab invented a triple-glazed window they hoped would revolutionise the building industry. Though windows with three panes had existed for years, what distinguished Berkley’s design from precursors was the presence of a centralised, thin layer of glass. This made the window lighter, as less material could be used to make the external panes. It also made the window more energy efficient, as compartments either side of the central layer could be filled with insulating gas.
On December 23, 1924, a group of international businessmen gathered in Geneva for a meeting that would change the world for decades. Delegates from all major lightbulb manufacturers were present, including the Netherlands’ Philips and the United States’ General Electric. While revellers celebrated Christmas elsewhere in the city, the group founded the Phoebus cartel, a supervisory body that would carve up the global incandescent lightbulb market.
According to PhysOrg, a scientific publication, scientific knowledge used in international studies is predominantly sourced from English-language documents, as it is assumed that all scientific knowledge is available in English. However, according to research scrutinizing over 400,000 peer-reviewed papers in 326 journals, published in 16 languages, scientific papers written in languages other than English may hold untapped information crucial to the conservation of global biodiversity.
For $200, you can now invest in the eco-fashion label Christy Dawn. The label is selling "plots" in the organic, sustainable cotton farm in India that provides the raw materials for their clothing. At the end of the season, you're paid back with store credit. If the harvest is good, you might get back more than the initial $200 you invested. On the other hand, if it's a bad year for cotton, you could lose most or all of your money.
Toyota was the leader in eco-friendly hybrid vehicles for many years, according to ArsTechnica. The automotive company had a fuel-efficiency edge over its competition. However, it has recently struggled to compete with companies that sell electric vehicles such as Tesla, Nissan and Volkswagen.
Toyota has made two critical choices. First, it tethered itself to hybrids. Second, it bet its future on hydrogen. But now governments around the world are moving to ban fossil-fuel vehicles of any kind.
Algae is used in lots of ways, from food to health supplements to fuel. Now we can add flip-flops to the list. Flip-flops, commonly made from rubber, foam or plastic, are hugely popular all over the world. When people lose theirs on the beach, which happens frequently, the flip-flops are swept into the ocean to join the rest of the plastic pollutants collecting there.
According to The Japan Times, the tragic events of March 11, 2011, when a massive earthquake and tsunami triggered meltdowns at three nuclear reactors in Fukushima, forced Japan to reconsider nuclear energy. Today, 24 of Japan’s 33 reactors remain offline.
After the disaster, the government increased its push toward renewable energy, but it also invested heavily in coal projects. The dirty fuel was seen as the fastest, cheapest and most reliable way to keep the lights on.
Electronic waste is a huge problem. There's an estimated 51,000 tonnes of it globally per year, says the European Union. But a new law could put an end to one part of it.
The E.U. has passed a law that as of 2024, all phones will have a standard USB-C charger. Having a single type of smartphone charging port will make cables interchangeable and more reusable. This standard charger would also improve the customer experience.
The Japan Times reported that most world leaders chose to fly to New York for the United Nations General Assembly, but Swedish teenage activist Greta Thunberg made headlines for deciding to sail instead.
The 2019 Nobel Prize in chemistry has been awarded to three scientists who played a large role in developing lithium-ion batteries: Stanley Whittingham of the U.K., American John Goodenough (at 97, the oldest Nobel laureate ever), and Japan’s Akira Yoshino. Whittingham created the first functional lithium-ion battery in the 1970s, then Goodenough increased its capacity two-fold over the next 10 years. Finally, Yoshino removed the pure lithium, making it much safer to use.
