When upcycling, reach for the moon
In September 2016, Henk Kamp, then Minister of Economic Affairs in the Netherlands, opened Upcycling Gemert, a plant that processes mushroom waste into compost, fuel and heat. Only two weeks later, a press release announced another project, called BIOrescue, that aims to upcycle the same mushroom waste by creating new bio-based products. Although I was
GreenTech 2019: new crops and technologies
GreenTech 2019 is the major horticultural fair, to be held June 11-13 in Amsterdam. As they say themselves: ‘GreenTech 2019 brings people and technology together to increase growth, productivity, sustainability, inspiration and pleasure in horticulture. Because we believe that improvement and innovation in horticulture will contribute to increased wellbeing for people.’ With 477 exhibitors, this is one of the major horticultural fairs in
Biosolar cells: moving forward step by step
Through biosolar cells, researchers try to improve photosynthesis, the process through which plants, algae and some bacteria capture sunlight. The product of such ‘artificial leaves’ is hydrogen for instance, that can be processed to fuels and chemicals, with CO2 and nitrogen. There are many research programs in the area of direct conversion of sunlight, and
Microalgae, environmental cleaners and food additives producers
The use of microalgae for water purification is not widespread. Yet, they are very well capable of doing so, says Paul Hamm. Twenty-five years ago, he was involved as an investor in water purification by microalgae. But he was too early. Government policy steered into another direction, and Hamm’s innovation lost its value in the
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
Biohydrogen: the next green alternative fuel
Hydrogen has a high energy content (120-142.9 MJ/kg); it is a clean energy carrier and can replace fossil fuels. Hydrogen is already a fuel of choice for space programs; it guarantees environmental quality and mitigates climate change. However, the presently used commercial methods for its production are not environmentally friendly; they require a major energy
Biocomposites for cars
Every year the European car industry uses around 80,000 tonnes of wood and plant fibres to reinforce composites, instead of synthetic fibres like glass and carbon fibre. Biocomposites have become increasingly popular with car manufacturers because they can reduce vehicle weight, which improves performance and lowers CO2 emissions. They are used in car interiors for
