Description of the waste generating technology

A kókuszdió hámozása során keletkező hulladék. A kókuszdiót egy éles fogakból álló, forgó késnek nyomják, mely lehántja a külső héjat.

Olajából üzemanyag készíthető, aktív szén állítható elő belőle, mely különböző szennyezőanyagok megkötésére képes. A kerti talajba keverve növeli annak víztartó képességét, mivel több, mint a saját tömege tízszeresét képes vízből magába szívni. Geotechnikai hálóként is alkalmazható.

Hazard characteristics
Not classified
No information
Measured harmful effects
No
Would it be suitable for soil reclamation in general?
Yes
Justification, references

Nagy szervesanyag tartalma miatt alkalmas lehet.

Would it provide sufficient amounts of special nutrients to the soil?
No
Would it suffice as an additive to growing media?
Yes
Justification, references

Szervesanyag tartalmának köszönhetően részét képezheti különböző mesterséges termesztőközegeknek.

Would it improve the structure of compacted soil and/or contribute to soil crumb formation of poorly structured soils?
Yes
Justification, references

Mivel nagy szervesanyag tartalmának köszönhetően javítja a talaj szerkezetét, ezért alkalmas lehet tömörödött talajok textúrájának javítására.

Would it be suitable for physical stabilisation and/or texture improvement of loose, quagmire soils?
No information
Would it be suitable for erosion prevention?
No information
Would it reduce the mobility and availability of the contaminants?
Yes

Would it be suitable for production of geotechnical elements?
Yes
Justification, references

A pálmamaghoz hasonlóan alkalmas lehet geotechnikai elemek előállítására.
