European horticulture faces challenges related to sustainability , specially considering the increasing importance of regional food production amidst global disturbance triggered by mood modification . The rife practices , both in high - technical school northern Europe and scummy - tech southerly Europe , are grade by unsustainability , resource intensity , and poor circularity .
A major government issue in sustainable horticulture is the choice of emergence media . Traditional soil , peculiarly peat , is harmful and source from fragile ecosystems . Alternatives like rock wool and organic substrates like bark exist , but they have limitations , such as lower water retention . ICL Group ’s wood - fibre ontogenesis medium , Fibagro Advance , assay to treat these challenges , but it still bank on forestry wood .
The EU ’s Horti BlueC labor explores orbitual and sustainable horticultural medium using waste sidestreams like mollusc permissive waste , works fibers , and used growth medium . reach fully recycled outgrowth media remain a challenge , with a stress on reuse H2O , nutrients , and fertilizer presenting proficient difficulty .
aquicultural indoor husbandry is suggested as an choice , potentially reduce the need for solid matter . Projects like Mosswool aim to supersede non - renewable stone woolen and peat in aquicultural systems , using sustainable materials like sphagnum moss moss .
Bio waste from love apple is being explored for various purposes . The Greenery uses tomato waste to make composition board box seat . Biopesticides descend from tomatoes are consider less toxic and biodegradable than synthetic alternatives .
gardening can add to circular systems by generating nutrient - rich organic issue . Bioflytech , ground in Alicante , employ organic wastes to feed insect larvae , which then become biofactories converting waste into mellow - quality organic fertilizers .
Some startups are turning horticultural wastefulness into raw food element . orbitual Fiber produces cooking flour from artichoke side watercourse , claim gloomy carbon and water footprints compare to traditional flours . Grassa in the Netherlands extracts usable protein and fibers from horticultural side streams for animal provender , aim to reduce the environmental footmark associate with soybean feed from South American plantations .
Sustainable gardening is recognized in Europe ’s Green Deal scheme , emphasize the motivation for a circular sphere to decrease final emission from agriculture . However , challenges include the environmental impingement of greenhouse cultivation and the motivation for regulatory input to encourage sustainable practices among growers .
