A Gentle Rant About CO2 and ‘Circular’ Greenwashing

Examining CO2 reminded me of some common misconceptions about circularity. These misconceptions are more common than I had expected, and lead to unhelpful greenwashing. They apply to all material flows, but CO2 is a good example. Continue reading A Gentle Rant About CO2 and ‘Circular’ Greenwashing

Hello 2023!

It’s been even longer, hasn’t it? I’m still here though. Perhaps I haven’t been blogging as much because as a researcher, the writer’s bandwidth I would have used here has been taken up by projects at work. Still, this evening I felt an itch to write a bit about what’s happened over the past year, and some plans for 2023 and beyond. Continue reading Hello 2023!

Climate Control Using a Genetic Algorithm (Part 2)

Over 6 months ago I started my MSc thesis – and now the project’s finished. This is a cursory but technical article where I share some of the results with you. A quick recap: There are many ways of controlling Continue reading Climate Control Using a Genetic Algorithm (Part 2)

Biobased Materials: Where Should They Come From, Where Should They Go?

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?

Circularity, Livestock, and Nutrients

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

Circular Horticulture, Part 2: Pitches

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

Circular Horticulture 2025, Part 1: Visions and Goals for Research

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

TechnoHouse at Rijk Zwaan

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

Rule-Based Climate Control Using a Genetic Algorithm

Greenhouse climate control consists of lots of if-then statements, basically decision trees. Can a genetic algorithm optimise these trees? I am about to find out in my MSc thesis. Continue reading Rule-Based Climate Control Using a Genetic Algorithm

GreenTech 2019: General Observations and an Aquaponics Presentation

A month ago I attended GreenTech 2019. There were quite some changes and new observations. Now for some proper substance – one of my favourite presentations at GreenTech 2019. Continue reading GreenTech 2019: General Observations and an Aquaponics Presentation
