European project with participation of the University of Hohenheim investigates how unprofitable fields can be used sustainably while adding value with renewable raw materials.

On 8 February, the European Parliament adopted its Own Initiative Report on the Circular Economy which recognised the role of bioplastics for the future. Amongst other issues highlighted, the MEPs emphasised the potential role of bio–based and biodegradable and compostable plastics in the circular economy whilst noting that bio-based and/or biodegradable plastics alone will not provide a solution to the environmental concerns related to plastics.

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.

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.

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.

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.

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.

Degradable biopolymers - 29/05/2020

Bioplastics make wood cycles more sustainable

Innovative technologies and bacteria can transform wood residues into sustainable bioplastic packaging. Before bioplastics are broken down into CO2 and water in an environmentally friendly way, they can thus lead lives as products in the cosmetics industry, for example.

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.

Fuel from CO2 – compact decentralised facilities enable emission-free mobility

Can greenhouse gases like CO2 and methane be used to fuel cars? What sounds like wishful thinking is in fact already reality at INERATEC. The company’s compact mobile systems equipped with a unique chemical reactor technology are attracting worldwide interest. The systems enable CO2-free mobility for road traffic, aviation and shipping. Is this development close to successful market entry?

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…

Building sustainably - actively protecting the climate

Using renewable and recycled raw materials, minimising the use of water and energy during construction works and subsequent operation of a building, conserving resources and protecting the environment while maintaining biodiversity are all important components of sustainable building construction.
