Chemically versus thermally processed brown shrimp shells or Chinese mitten crab as a source of chitin, nutrients or salts and as microbial stimulant in soilless strawberry cultivation

Brown shrimp (Crangon crangon) shells and Chinese mitten crab (Eriocheir sinensis) were chemically demineralized and deproteinized (denoted as M1 to M4 for the shrimp shells and M5 to M7 for the Chinese mitten crab), and shrimp shells were torrefied at 200 to 300 °C (denoted as R200, R255, R300), and were compared with a commer cially available...

Semantic interoperability for data analysis in the food supply chain

Food supply chains consist of many links and operate on a global scale with many stakeholders involved from farm to fork. Each stakeholder maintains data about food products that they handle, but this data is not transparently available to all stakeholders in the chain and trust in data sharing is low. In addition, there are various other data...

Capture of carbon dioxide using membrane gas absorption and reuse in the horticultural industry

The principle and engineering aspects of the membrane gas absorption process are discussed. It is shown that membrane gas absorbers have size advantages over conventional equipment. A suitable choice of absorption liquids and membranes is necessary to achieve a workable system. Significant reductions in the energy consumption of absorption...

Adembeschermingsmiddelen in de glastuinbouw: Niveau en duur van de bescherming

Op verzoek van STIGAS is onderzocht in welke mate gangbare adembeschermende middelen in de specifieke situatie van de glastuinbouw de concentratie aan geinhaleerde toxische stoffen reduceren. Het blijkt dat in alle gevallen van toepassing van bestrijdingsmiddelen afdoende reductie mogelijk is. Een volgelaatsmasker met filter-ventilator voldoet...
