Greenhouse horticulture is tuned to grow crops, and everything else a plant produces is treated as waste. Reharvest looks at the greenhouse as a source of biomass for other industries and follows four material streams: plant fibres, juices, residual matter and the harvest itself. The research included visits to a wide range of companies and their technologies, and produced the pictures, interviews and artefacts in the show.
At the centre stands a greenhouse module that actually grows plants, with its own ventilation, water and lighting, inside semi-reflective walls that echo the scale of the greenhouse complexes. Four arms extend from it, each presenting new applications through graphics, short texts and prototypes made with biomaterials such as mycelium, colourants, oils and insect protein. Reharvest was first shown at the Emergence Delft EXPO 2025 in Rotterdam.
