Drying of sea weed
Drying of sea weed
Type of treatment: Pretreatment
Description:Sea weed and sea grass are disposed in piles (e.g. 2m x 2m), height must not exceed 20 cm.
Waste:
Sea weed and sea grass lightly (to medium) oiled
Situation/Possibilities in the country:
Pre-treatment can be implemented very easily with limited equipment (earth moving equipment).
Interest:
Allows decreasing the overall weight of a minimum of 50% of the sea weed and grass (and removing water) before incineration, thus reducing the cost and facilitating the incineration.
Entry criteria:
Drying is used for lightly to medium oiled marine vegetal waste.
Operational constraints:
Ground must be protected to avoid infiltration.
Impacts:
Environmental impacts are limited to the odours (if infiltration is managed).
Legal constraints:
Limited.
Efficiency:
In temperate country, sea weed dries off in 15 days, less on hotter conditions.
Cost:
Limited to the rental cost of earth moving machines, personnel and land.
