Researchers at the University of Freiburg quantify the amount of material needed to enable people to live without poverty. 1.2 billion people live in poverty. To lift them out of it, an average of about six tons of raw materials are needed per person and year – in particular minerals, fossil fuels, biomass and metal ores. This is the result of a study by researchers from the Chair of Sustainable Energy and Material Flow Management.

Basic chemicals, which are needed as raw materials for a wide range of products such as medicines and detergents, can currently only be produced with an enormously high input of energy and raw materials. In many cases, fossil fuels and raw materials are still used. The extraction of chemical substances alone requires high temperatures, expensive catalysts made of precious metals and, in some cases, environmentally harmful starting materials.

Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

European collaborative project led by the University of Hohenheim shows: Combining bioethanol production with carbon storage can effectively reduce CO2.

Renewable raw materials and the circular economy in the textile industry - 08/12/2021

Outdoor equipment made from cellulose, castor oil and coffee grounds - functional and durable

VAUDE develops outdoor gear made from natural or recycled materials that are harmless to people and the environment while protecting against the wind and rain. The company relies on renewable raw materials, biobased plastics and the circular economy.

Carbon dioxide is one of the main drivers of climate change – which means that we need to reduce CO2 emissions in the future. Fraunhofer researchers are highlighting a possible way to lower these emissions: They use the greenhouse gas as a raw material, for instance to produce plastics. To do this, they first produce methanol and formic acid from CO2, which they convert via microorganisms into building blocks for polymers and the like.

Refuels are renewable fuels that can be produced in different ways. When they are mixed and processed such that they meet the existing fuel standards, they are suited for all types of combustion engines. This is the result of the latest vehicle and fleet tests within the project “reFuels – Rethinking Fuels” at Karlsruhe Institute of Technology (KIT). Compared to fully fossil fuels, refuel mixes allow for a CO2 reduction by 25% at least. Moreover,…

The European Union is largely dependent on imports of white phosphorus (P4), a strategic raw material for the food and pharmaceutical industries. To tackle this challenge, the newly started four-year EU-funded project FlashPhos – led by the University of Stuttgart – will recover at a large scale high-quality white phosphorus and other raw materials using sewage sludge as input material.

Energy park & Donau-Silphie: a symbiosis that benefits nature

Biogas plants that produce non-fossil fuels are very much in vogue at the moment. In the Swabian hamlet of Hahnennest, four family farms have joined forces to form an energy park and operate a local biogas plant, covering everything from substrate production to the sale of energy.

Perspectives of methane as energy source - 18/06/2020

New technologies for using biogas as a balancing energy

The microorganisms in biogas plants do a great job biologically converting CO₂ and hydrogen, which are primary fermentation products, into methane. Biomethane has a great future as an energy source. Scientists at the University of Hohenheim are investigating new ways to produce and use biomethane.

Biogas and wood as components of the energy transition - 10/02/2020

New perspectives for bioenergy

Decentralised, controllable and stable - renewable energy is an important component in the transition to a bioeconomy without fossil fuels. BIOPRO spoke to PD Dr. Andreas Lemmer from the State Institute of Agricultural Engineering and Bioenergy at the University of Hohenheim and Prof. Dr. Stefan Pelz, scientific director of the Institute for Applied Research and professorat the University of Applied Forest Sciences Rottenburg.

Two-part interview part 1 | Prof. Dr. Regina Birner on the green genetic engineering debate - 12/08/2019

Agricultural economist Birner calls for other forms of dialogue besides organized interest groups

Green genetic engineering continues to divide opinion in Germany in the same way as CRISPR/Cas and other genome editing (GE) techniques. What are the consequences for the bioeconomy, which involves key areas of biotechnology? We talked with Prof. Dr. Regina Birner, agricultural economist and head of Hohenheim University’s Department of Social and Institutional Change in Agricultural Development at the Institute of Agricultural and Social…

Providing Growledge - resources and products for the bioeconomy

Miscanthus and hemp are biomass plants that can be used as raw materials for a wide range of products and can be grown on land areas that are currently underutilised. A European consortium led by the University of Hohenheim in Baden-Württemberg has started a five-year project to demonstrate the economic potential of these plants.

Environmentally friendly alternative to fossil natural gas: methane from biomass

In cooperation with the research unit of the German Technical and Scientific Association for Gas and Water (DVGW), KIT researchers have built a pilot plant in which biogas produced by fermenting residual organic materials can be upgraded to synthetic methane (synthetic SNG). Biobased methane is not only a sustainable energy source for the heating and transport sectors, but also opens up new opportunities for temporary storage of renewable…

The alternative: “bioplastics”

Plastic waste takes years to decompose and pollutes the environment. Nevertheless, plastics are an indispensable part of everyday life. It is therefore all the more important to find a meaningful alternative that is sustainable, environmentally friendly and has better properties and more functionality than conventional plastics. In addition, such an alternative should not be dependent in any way on fossil resources.

Industrial biotechnology a challenging change to the raw material base

Biogenic raw materials have never been as popular as they are now. Efforts to tap renewable carbon resources are already underway, despite the fact that new oil drilling technologies are boosting fossil fuel stockpiles. In the medium term, industry will have to expand its raw materials base, and in the long term it may have to renew it completely. Industrial biotechnology is one of the key technologies in the transition.

Bioeconomy a new model for industry and the economy

On the one hand, a bioeconomy relies on renewable resources to meet society’s need for food, energy and industrial products. On the other, it emphasises the role of biogenic material flows. The bioeconomy model is expected to reduce our dependency on fossil fuels in the long term. In order to implement the shift to a biobased economy on the regional level, the Baden-Württemberg government launched the Bioeconomy Research Strategy in summer 2013.

Extremophilic bacteria

Extremophilic bacteria love it hot, sour or salty, toxic substances like heavy metals also do them good and even give them energy. As molecular and systems biology techniques get better and better, industry is also becoming increasingly interested in these exotic organisms. What potential does knowing the biochemistry of extremophilic bacteria have for the pharmaceutical, cosmetics and sanitary articles industries?

Biogas a promising source of renewable energy?

In addition to sunlight water and wind biogas is a regenerative source of energy that contributes to saving fossil resources. Germany is home to around 7100 biogas plants including 796 as of 2011 in Baden-Württemberg. In 2010 these facilities produced 11 per cent of the electricity generated from renewables in Germany. Energy-rich methane is the major constituent of biogas and is produced when organic compounds are broken down by bacteria in the…
