For quite some time now, the European Commission (EC) is putting a special focus on biodegradable and compostable polymers when assessing the general role of bioplastics.

Paper production from plant fibres - 20/01/2021

In one cycle: ecopaper, energy and fertiliser made from Silphium perfoliatum

Many consumers don't care about exactly how their paper packaging is made and what it is made of as long as it is "eco". But even producing recycled paper, trees need to be felled. An alternative could be paper made from cup plant. Together with partners, a company called Silphie Paper has developed concept for obtaining fibres for a new type of grass paper, while also producing heat, energy and nutrients for natural fertilisers.

Chitin for the development of sustainable materials for use in the construction and other industries

Pliable and robust, light and stable - it sounds like an ideal material for the construction and many other industries. A team of researchers at the University of Stuttgart is researching what purposes the naturally good properties of chitin can serve.

As healthy and tasty as mushrooms might be, they are good for much more than just the dinner plate. The Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT has now teamed up with the Fraunhofer Institute for Building Physics IBP to investigate the use of fungus-based materials for the fabrication of eco-friendly sound absorbers.

The wastewater treatment plant is turned into a vegetable farm, bio-based substances recovered from waste are being utilized to prevent oxidative spoilage in food packaging or provide environmentally-friendly and safe water-repellent coatings on functional textiles. In the EVOBIO project coordinated by Fraunhofer IGB, 19 Fraunhofer Institutes are working on solutions for a sustainable economy.

The results of the European Bioplastics’ (EUBP) annual market data update confirm the continued dynamic growth of the global bioplastics industry. “Our industry has successfully weathered the challenges posed by the Covid-19 pandemic. And the outlook for bioplastics is also promising as the global market is predicted to grow by 36 percent over the next 5 years”, says François de Bie, Chairman of European Bioplastics.

Development of biogenic packaging - 16/11/2020

Sustainable packaging - the devil is in the detail

Modern packaging often boils down to a tick list of biogenic origin and/or biodegradability. But comprehensive sustainable packaging concepts need more than just that. Perishable foods, for example, require special barrier properties. The Albstadt-Sigmaringen University of Applied Sciences is researching packaging concepts for their sustainability.

Packaging of the future

What will the packaging of the future look like, and what will be required of it? Can packaging be biobased, recyclable, sustainable and economic? In Baden-Württemberg, there are various approaches to developing packaging with the above properties from various sources including agricultural residual and side streams as well as municipal waste.

A new future study by the Fraunhofer Institute for Systems and Innovation Research ISI uses four different scenarios to provide insights into how natural resources could be used in agriculture in 2035 and what role digital decision support systems can play for farmers in this context.

In a review article recently published in the scientific journal Waste Management, ATB scientists outline the possibility of using insects to efficiently and sustainably recycle food waste. This insect-based bioconversion can help to close material cycles in the food value chain.

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

The European Environment Agency (EEA) recently published its new report “Biodegradable and compostable plastics – challenges and opportunities”. The report highlights many positive aspects of biodegradable and compostable plastics. Unfortunately, its interpretation in several media outlets focused exclusively on the few critical assumptions the report makes regarding consumer perception.

Packaging protects products during transport and storage. In order to develop sustainable packaging and conserve resources, Henkel developed an evaluation tool that quickly and reliably checks plastic packaging for recyclability. The tool has now been expanded to include common materials, so that packaging made of paper/cardboard, glass, aluminum and tinplate can be analyzed in addition to plastic. Fraunhofer UMSICHT tested the software tool.

Since the beginning of 2019, the Fraunhofer Institute for Biomedical Engineering IBMT has been working on a comprehensive characterization and humantoxicological assessment of nanocellulose along its life cycle in the BMBF-funded joint project "NanoCELL" under the coordination of Postnova Analytics GmbH, in order to achieve a reliable risk assessment and safe use in environmentally friendly packaging materials.

Qualitative soil fertiliser - 10/07/2020

How natural cycles can be closed with wood ash

Recycled material instead of waste: wood ash is good for soil and plants - if the quality is right. The German Federal Quality Association for Food Ash ensures reliable wood ash standards with its certifications. The RAL-Dünger label for fertilisers provides the necessary certification for natural wood ashes to be used in the circular economy.

rezemo GmbH - 26/06/2020

Coffee capsules: wood instead of aluminium

In Germany alone, around three billion disposable coffee capsules made of aluminium and plastic are sold every year. This creates a gigantic waste problem, as only a small proportion of the capsules can be recycled. Fully compostable wooden coffee capsules might be a solution to this problem. The capsules have been developed by a start-up company called rezemo, which also has other biobased packaging solutions in the pipeline.

Global population is increasing, crucial resources become scarcer. Producing enterprises today have to take the right steps for a sustainable future. On their behalf, scientists of KIT study how the production process may be improved by autonomous production control, reduction of wear parts, or principles of resource-efficient production. Their know-how is presently being pooled in the new research focus “Sustainable Production.”

Biosensors - 09/04/2020

Sensors for the bioeconomy

Sensor networks are one of the keys to achieving digitalisation of the bioeconomy. Sensor networks are on the way to becoming important analysis and control instruments for energy-efficient and sustainable material cycles. Dieter Hertweck, Professor of Business Information Systems at Reutlingen University of Applied Sciences, shows what is already possible in digital agriculture and waste recycling and what is feasible for the future.

"European Bioplastics (EUBP) welcomes the new Circular Economy Action Plan (nCEAP). It’s an ambitious step forward to transform Europe into a circular economy”, says François de Bie, Chairman of European Bioplastics. “As EUBP, we especially endorse the European Commission’s (EC) commitment to support the ‘sustainable and circular bio-based sector through the implementation of the Bioeconomy Action Plan’”

Polysecure GmbH - 16/01/2020

Recycling of the future – marked plastic as a circular product

Plastics are harmful to the climate and human health both during manufacture and combustion and they also clutter our planet with garbage. Recycling is therefore a key issue, but it is not efficient. Polysecure has developed a process for permanently marking individual plastics that enables them to be separated efficiently and returned to a circular economy. This would counteract the vast amount of (micro) plastics and reduce CO₂ emissions.

Plant pots made of natural fibres – "bio", no ifs or buts

Plastic plant pots are not good for the environment; strictly speaking, they should not even be disposed of in recycling bins. Alternatives such as coconut fibre pots are compostable, but not pollutant-free and not "bio" at all. The Karlsruhe-based company Fiber Engineering has developed a truly ecofriendly way to grow plants: pots made of hemp or grass, which are preserved with biological components and decompose completely within a…
