Beyond-Burger
There are many vegetarian and vegan meat alternatives. Not all of them actually taste like meat or even similar to meat. Things are supposed to be different for the ‘Beyond Meat Burgers’, the third generation of ‘meat substitutes’. Taste, shape, color, texture and consistency are said to be similar to meat burgers. Commercial brand products of ‘Beyond Meat Burgers’ have only been available in Germany for a short time, but the demand is already huge. Their meat-like consistency and frying properties derive from a protein isolate of pea, soy or wheat. Beetroot juice is used, among other things, to imitate meat juice and keep the patty juicy. Other ingredients are vegetable oils, various flavors, stabilizers and antioxidants - the vegan patties still cannot do without additives.
Lupine ice cream
One of the most distinctive protein plants in Germany is lupine, whose seeds have a protein content of 35%. With the blue sweet lupine Lupinus angustifolius, researchers found a variety that hardly contains any bitter substances (alkaloids), grows well in the local climate even in poor soils, is resistant to many diseases and has therefore become interesting for the food industry. As a nitrogen fixing plant, the lupine is a ‘soil improver’ and does not need to be fertilized. Meanwhile, various lupin-based foods are being developed. The first commercial product is an ice cream, which is available in supermarkets. It is interesting for vegetarians and vegans as well as for allergy sufferers.
Oat drinks
Lupines, soya, oats, almonds, rice and other seeds are now widely used to make drinks that can be used as an alternative to milk. The possible applications go beyond milk drinks (e.g. in coffee or muesli), more and more offer alternatives to classic dairy products such as yoghurt (e.g. made from oats, soya, coconut), cheese (e.g. made from lupins, almonds, cashews), crème fraîche (e.g. made from oats) etc. The increased demand for plant-based products leads to a growing number of attractive products, available to all consumers.
Insect bars
More than 2,100 different species of insects and spiders are currently consumed worldwide. Insects have a much smaller ecological footprint than cattle, pigs or chickens. Crickets for example, produce only 1% of CO₂ emissions per kilo of protein compared to beef. From an ecological point of view, a change in diet away from traditional meat to insects would be very desirable. However, both in terms of taste and ‘disgust’, there is considerable reluctance to eat insects, particularly in European cultures. Apart from curiosities, such as burgers, energy bars, insects ‘in one piece’ (alive or dried) to versatile insect flour, insects are primarily discussed at present as feed for classical meat and fish breeding (e.g. instead of imported soya). But insects could and will also be included in many other bioeconomy products in the future - for example, insect oil in cosmetics or fuels as well as chitin in plastic substitutes.
Wooden clothes
Surely our early ancestors used bark to protect themselves from wind and weather. But of course, you cannot imagine clothes made of wood like this anymore. Modern wooden clothing is neatly woven from wood fiber yarn. Wood-based fibers consume up to 20 times less water than conventional cotton fibers. In addition, unlike cotton plants, trees can do without pesticides and fertilizers. Since trees grow in our latitudes, transport distances could be minimized. Apart from the positive environmental aspects, wooden clothing is said to have properties which are very important for clothing: The fabric is permeable to air and balances temperature. The fabric quickly absorbs moisture and releases it directly back into the air. Thus, wooden shirts cool when warm, and warm when cold. Of course, wooden clothing can also be printed with a stylish bark pattern.
Leather and garments made of fungal fiber
There are almost countless different species of fungi with great properties. Yet their cultivation and economic potential has hardly been developed. Fungal fibers can be processed into clothing, for example. Among other species, the widely used tinder sponge, which Özi already knew, is used for this purpose. The fluffy, soft basic material is called Trama and was in the past a well-known textile material. Today, the craft of making clothes from Trama is almost extinct. It is possible, however, that fungi as textile raw materials is experiencing a new upswing due to the rising veganism. Vegan leather substitute products can also be produced from the mycelium of forest mushrooms, i.e. from their root network. These are fed with waste from agriculture and manufactured into products such as furniture, shoes and all kinds of other leather products.
Shoes made of fish skin
Fish skins are a waste product of aquaculture and fisheries that are usually disposed of. However, they can actually be tanned and processed into attractive leather. A shoe with a sturgeon pattern or a jacket made of iridescent salmon leather are quite chic yet do not become slimy in humid weather. Several - mainly small businesses - have specialized in fish leather and serve a high-priced market with unusual shoes and other leather products.
Clothes from algae
Many of our waters are over-fertilized and various algae feel very comfortable in them. These algae can be harvested with a clear conscience to make clothing from their fibers. Algae clothing is now offered by numerous manufacturers. Currently, algae only provide a part of the fibers, but nevertheless, often almost 50% of the product consists of algae fibers. Most of the fibers are made from seaweed. They do not at all smell fishy and do not fall apart when it rains. The active ingredients contained in the algae are also said to promote cell regeneration and to reduce itching and skin diseases (such as neurodermatitis). Should the advertised properties of the ‘healthiest shirt in the world’ prove to be true, algae fibers certainly have a great future ahead of them.
Bacterial lacewing silk
Green lacewings are small green flies with golden eyes that eat aphids. They attach their eggs on extremely flexible stalks up to 10 mm long - made of a hardened protein excretion - on the surface of the leaves. These egg stems, or better said, this lacewing silk, is extremely flexible and stable. The mechanical properties of the egg stems were biotechnologically reproduced as a fiber. Using bacteria, the lacewing silk can now also be produced on a large scale and is used in medical technology and as a reinforcing fiber for lightweight construction, for example in the production of cars, airplanes, or ships.
Packaging material
The fact that packaging material is still made of plastic must come as a surprise, ecause there already are countless alternatives today. Fiber-cast packaging, for example: material containing fibers is ‘cast’ into a precisely fitting packaging according to the shape of the article to be packaged, which optimally protects the product and saves material at the same time. Fiber-cast packaging can be pressed directly from agricultural waste that is not used for other purposes. Optionally, mushrooms can be grown on this waste to improve and stabilize the shape of the packaging. At the end of the day, these bio-economic packaging materials can be easily composted.
Paper from grass
The first paper was made from papyrus – a grass that grows in swamps. Since then, the demand for paper has increased tremendously. Nowadays it is mainly produced from wood. But paper can (once again) be made from grass – from grass that can be mowed from meadows several times a year. Grass paper is particularly suitable for packaging materials and cardboard. But it can also be used for digital and offset printing, for brochures, labels, booklets, and business cards.
Dandelion tires
Car tires used to be made exclusively from rubber – the sap of the hevea tree, which is still widely cultivated in the tropics today. Other plants that produce sticky sap, such as the dandelion, are also suitable. The company Continental has presented a first test tire, which is partly made of rubber and partly of dandelion. A particularly high-yielding and robust variant of the Russian dandelion was specially bred for this purpose. The long-term goal is to find an ecologically, economically, and socially sensible solution to the growing demand for natural rubber that will relieve the growing areas for the traditional rubber tree in the tropics. The rubber dandelion can be cultivated on previously unused land in the temperate latitudes of Europe - and thus in geographical proximity to the European tire plants. This significantly reduces logistics costs and environmental pollution.
Plastics are omnipresent in our living environment, and many of them can be made from bioeconomically produced raw materials. These can be synthetic fibres, but also classic plastic items such as cutlery, plates, paper and much more. There is still a lot of development potential here. Material saving, monomaterial and recyclability are the keywords of the future. Monomaterial packaging is the term used to describe packaging that consists of only one type of material, in order to improve the sorting of waste and thus its recyclability.
Leather and clothes made from mushroom fibers or fish skins, clothes made from scraps of wood or algae are already a reality today. Fibers suitable for producing clothing can be developed from an incredible variety of bioeconomic raw materials, ranging from sheep to bacteria. Today, a market for these alternative products has developed especially in the fashion sector. Some are ready for the market, and many of them are now considered fashionable and chic.
There are major challenges in the food sector, but also many innovative ideas and products. For instance, products that we often come across when shopping are the Beyond Burger, lupine ice cream, oat milk and insect bars. Generally, regional foods require less transportation and therefore less fuel. Vegan food produces less greenhouse gases, uses less land and conserves groundwater. Last but not least, food packaging also requires plastic alternatives, resource efficiency and recyclability. The fewer animal products, the fewer livestock; the more regional and less packaged, the more ecological and bioeconomical.
