The circular economy is something I was happy to see feature heavily at GreenTech 2020. It seemed to be on everyone’s mind when discussing sustainability, and there was even a dedicated session on it. The topic: vertical farming’s role in the circular economy. Continue reading Circular Urban Farming at GreenTech 2020
Achieving zero emissions in greenhouses is a big challenge. I’m not just talking about CO2 emissions. Greenhouses emit fertiliser and pesticides into the environment as well (see this article for more background on that). Water is only 2-3% of a Continue reading Water Usage in Zero-Emission Greenhouses
Energy efficiency is a big theme in greenhouse horticulture. I’ve called it the elephant in the room for vertical farming, but greenhouses have the advantage that most of their energy is free: solar energy. Still, a lot is being done on making the most of that solar energy and minimising fossil fuel consumption. A lot of that is in line with the circular economy as well. This is a summary of what four speakers at the energy session at GreenTech brought up. Continue reading Energy Efficiency at GreenTech
Indoor agriculture is touted as sustainable, but it requires a lot of materials – plastics, rockwool, and packaging, for example. How can these be made more circular? Continue reading Biobased Materials: Where Should They Come From, Where Should They Go?
What should the broad vision be to achieve circularity? Circularity is a big theme on this blog. I usually talk about indoor agriculture, but the same concepts apply to our whole food system. At the NVTL’s conference, Martin van Ittersum gave a presentation on a compelling vision to achieve this. Continue reading Circularity, Livestock, and Nutrients
Back in 1947, computer science pioneer Alan Turing foresaw machines that could learn from experience. 73 years later, everyone seems to be yapping on about ‘big data’ and ‘machine learning’, as I have on this blog as well. Where conventional programming starts Continue reading LetsGrow Using Data in Greenhouses
Last week, Heeren XVII, the biosystems engineers’ society at Wageningen University, organised an evening featuring three companies in the greenhouse horticulture industry. The first of these was Ammerlaan Construction (known as Maurice Kassenbouw in The Netherlands and Belgium), presented by Continue reading The Untapped Energy in Water Vapour
Last week I attended Wageningen Research’s Greenhouse Horticulture business unit’s event on research into circular horticulture for 2025. After the main presentation on the group’s vision and ideas (which you can read about here), there were six short presentations. Three Continue reading Circular Horticulture, Part 2: Pitches
Last Thursday I attended Circular Horticulture 2025, an event organised by Wageningen Research’s Greenhouse Horticulture business unit. The topic was their vision and goals for future research within circular horticulture. Continue reading Circular Horticulture 2025, Part 1: Visions and Goals for Research
Two Saturdays ago I went to TechnoHouse, an event organised at Rijk Zwaan’s headquarters in Westland, for sharing knowledge, networking, and showcasing the latest in breeding vegetable crops and greenhouse horticulture. Continue reading TechnoHouse at Rijk Zwaan
