Tree bark: an untapped resource
In comparison to wood, tree bark is a very versatile resource. It consists of several layers, each with their products. It contains anti-microbial and anti-oxidant compounds that could be used as preservatives. Prospective medicines and flavourings. Raw materials for adhesives, insulating materials and water purification. But only recently has industrial interest sparked in doing something
Efficient protein production and utilization
The world runs into planetary boundaries, or has transgressed them already. The three main problems can all be alleviated by a more efficient agriculture. Being: emission of greenhouse gases, excess of nitrogen fertilization, and biodiversity loss. But we will only succeed in doing so, says Johan Sanders, if we treat these jointly: above all, we
Circular agriculture, the model of the future
In September 2018, the Dutch minister for agriculture Carola Schouten announced that circular agriculture will become her main policy goal. Circular agriculture, also known as low external input farming, is the model of the future. The minister intends to remove obstacles to it, and to stimulate this model all across the country. An old principle
Innovative solutions for small farmers and organic farming
Mycorrhiza fungi increase yields in a targeted and environmentally friendly way, robots help farmers to control weeds ecologically. Smallholders optimise outputs with sensors in the soil and with modern biorefineries. Both smallholder and organic farming can benefit greatly from technological developments and innovative solutions while holding on to their ideals. Nova-Institute organizes the ‘Revolution in
Seaweed biorefinery: much work, high hopes
After an initial period in which ideas went in all directions, proponents of seaweed (macro-algae) in the bio-economy have now set down to the painstaking work of developing and fine-tuning their technologies. Single-product facilities, like for the production of biogas or proteins, have effectively been abandoned. It is now generally recognized in the sector that
New vegetable oil sources for the European oleochemical industry
The COSMOS Horizon 2020 EU research project aims at reducing the dependence of Europe’s oleochemical industry on imported tropical vegetable oils. It now imports much coconut, palm, palm kernel and castor oil for the production of products like plastics, detergents and plasticizers. At a stakeholder workshop preceding the 10th EFIB, 9-11 October 2017, in Brussels,
Bio-waste valorisation
Bio-waste is problematic from two sides. It may be a problem to dispose of it, and it represents an unused value. In a world where ‘there is no such thing as waste’, it should be valorised. That is: upgraded in an industrial process, insofar as the waste is not required as a fertilizer and soil
Fibres of the future 2: cellulosic fibres from wood
Wood contains cellulosic fibres, embedded in lignin and hemicellulose. Pure cellulose can be processed to a quality from which yarns can be spun. The most well-known of these products is viscose. The viscose process however involves the toxic and highly inflammable solvent carbon disulphide and is now abandoned in most countries. On the other hand,
