Drying of sea weed

Drying of sea weed

Type of treatment: Pretreatment

Description:
Drying of oiled sea weed and sea grass before incineration.

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:
The drying requires non sensitive land areas.

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.
