a possibility to reduce nutrient levels and produce commercially interesting metabolites
The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for …
This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato …
Med spillvärme från LKABs gruvindustri
Städerna växer och samtidigt ökar efterfrågan på närodlade och ekologiska grödor. För att klara av att producera närodlat och mer hållbart skulle ett alternativ vara att odla i så kallade vertikala växthus. I Kiruna finns Sveriges största malmgruva som drivs av företaget LKAB …
… for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in …
