The plastic is tough, heat-resistant, and a good barrier to oxygen, making it suitable for food packaging. Due to its structure, the new plastic can also be recycled and degraded back to harmless sugars.

Called H2arvester, a prototype has been installed on sugar beet land in Oude-Tonge, South Holland. Four solar "cars", measuring 12x6 m each, hosting a total of 168 solar panels and an irrigation system, are able to move 10 meters per hour. Combined with an electrolyzer, the system can also produce (green) hydrogen!

The Borgen Project presents a collection of inexpensive eco inventions that make life a bit easier for people in the global south, including a personal water filter, a manual irrigation pump, hotpot solar ovens, a solar water purification kit, and the maya pedal, a range of pedal powered machines in Guatemala.

A green district heating scheme using a giant heat pump in Gateshead, UK provides heat for 5,000 homes, replacing the need for gas boilers. New research at the University of Leeds outlines the benefits and challenges of shared ground heat exchange. Energy to heat buildings contributes around a quarter of UK greenhouse gas emissions.

A team at the University of York, UK discovered that antimony selenide, a semi-conductor used in solar panels, can auto-repair its broken bonds and are how looking at how longer-lasting panels could be created. Another team at Technion - Israel Institute of Technology are experimenting with lead-free perovskites, that are also self-healing.

Huanggang Vertical Forest City ComplexHuanggang Vertical Forest City ComplexAfter four years, Stefano Boeri Architetti has completed the Easyhome Huanggang Vertical Forest City Complex. It covers an area of ​​4.54 hectares, and has been designed to create a new green complex capable of integrating buildings for residences, hotels and large commercial spaces. The complex was intended to meet the daily needs of residents, temporary guests, inhabitants and tourists. It comprises five towers, two of which are residential and designed as vertical forests capable of providing a new life experience for the surrounding urban and natural area. The two residential towers, 80 metres high, are a form of 'vertical forest' with over 400 trees, 4,620 shrubs, and 2,408 sq. metres of perrenials, flowers and climbing plants that will absorb 22 tons of CO2 and produce 11 tons of oxygen per year. The floors have cantilevered elements, with open and closed balconies, that interrupt the regularity of the building and create a continuous ever-changing movement. Local species of trees have been selected, mostly Ginkgo biloba.

If you are wondering what to do with your old denims, buttons, bottle caps, plastic bags, wires, cables, pc components, and other items, well, why not just give them to a true artist, for example Deniz Sagdic of Mersin, Turkey. The video is from her "Ready ReMade" exhibition at Istanbul airport and no commentary is needed: Upcycling at its best!

Ironically, organic fruits and vegetables sold in supermarkets tend to use more plastic foil in order to distinguish them from non-organic produce. A high definition laser  available since 2016, but not yet widely used, could help change this. The laser beam removes part of the pigment from the outer layer of the peel of fruits and vegetables leaving a permanent mark. It is marketed as Natural Branding©, and it is developed by JBT and LaserFood.

Leather from fish skinsIctyos, a French startup calling itself an 'eco-responsible tannery', is collecting salmon, trout and sturgeon skins from restaurants and turning them into luxury leather goods such, bags, wallets and watch straps. True to the circular economy philosophy, skins destined for destruction are recovered, thus the process does not increase fishing. In addition Ictyos use vegetable tannins (for colouring) composed of leaves, roots or fruits to minimise deforestation.

New research by Luke Dunning of the University of Sheffield shows that some of our most widely grown crops supplement their genetic information with stolen genetic secrets. Apart from grasses, bacteria are also masters in this regard and this leads, among other thing, to antibiotic resistance. New evidence however documents evidence in a broad range of animals and plants, including aphids, whiteflies and psychoactive mushrooms!

Transparent Solar CellsTransparent Solar CellsAn international team led by Professor Joondong Kim of Incheon National University, Korea has developed the first transparent solar cell. The scientists hope that this next generation solar cells can be integrated as windows into all types of buildings, appliances with glass screens such as laptops, TVs and smart phones and even vehicles and crafts of all types. The transparent quality is thanks to a combination of titanium dioxide and nickel oxide semiconductors.

The study can be found in the Journal of Power Sources:

Wind Tree outside Roland Garros StadiumWind Tree outside Roland Garros StadiumImagine a world where we all produce our own green energy in our homes and offices and share it with each other in a world wide energy web. This was the vision of Jerôme Michaud-Larivière who invented the Wind Tree, an innovative, esthetically pleasing, and bird-friendly wind turbine. Each Wind Tree helps save the equivalent of 864 kg of Coal every year!

The original model of the Wind Tree is composed of 3 steel trunks that stem into tinier branches on which the 36 leaf-shaped wind turbines are attached. It can exploit all types of wind, from gentle breezes to powerful gusts of wind in both urban and rural environments. The Wind Tree can be installed close to buildings, which is a plus in urban spaces. A further innovation was the "aeroleaf hybrid", which added a high performing photovoltaic petal to the bottom of each leaf.

There are actually three types of Wind Trees - the original Wind Tree, the highly customisable Modular Tree, and the smaller and cheaper Wind Bush which starts from Euros 19,500. They can be customised by leaf colours, trunk colours, led lights, charging ports, air-purifying leaves, and usb benches.

Commercially launched in 2018, the innovative Wind Tree has already won several awards, however it is not yet a common sight in cities. One possible explanation may be the price and the lack of a full installation service.
