I have turned your pic. More below. In Scotland generations of crofters collected sea weed to fertilise the thin soils on the islands such as Uist. As it rots down it is prone to smell. More here... https://croft.garden/2014/01/29/marine-harvest/
Quote link above.. "Known locally as ‘tangle’, kelp species (Laminaria sp.)
are washed ashore by winter storms and collected
fresh from the beach when the tides and winds allow.
Seaweed is then left in piles for several weeks to start
decomposing, which concentrates the nutrients and
reduces its volume for spreading. Rotten seaweed
is spread on machair plots during late winter or early
spring before they are cultivated by plough or rotovator. "
KEY
POINTS
• 15 tonnes/hectare of rotten
seaweed can meet the nitrogen
and phosphate requirement of
a crop on machair soil
• Seaweed also increases
organic matter and provides
trace elements
• As well as feeding the soil,
seaweed can help stabilise it
and prevent erosion
I'm assuming that, because beaches are notoriously inaccessible, if only to stop the public driving their cars on to them, this perfectly valid exercise becomes impractical and thus uneconomic. Everything above is well founded but using seaweed 'raw', straight off the beach, on a plot can be a good deterrent for slugs via the salt content.
I believe silver surfer is correct but was hoping it could be used instead of thrown away.
Yes it is possible, but needs someone with a business, money, lorries,tractors and a huge vacant area to stack it all while it breaks down. Maybe writing to your local newspaper or contacting a TV station you could start the idea of someone doing this.

No one would want to sit on a beach amongst stinking sea weed.
