Description of the waste generating technology

A dió csonthéjának eltávolításával keletkezett növényi rész.
Két forgó henger között megtörik a csonthéjat, majd egy speciális osztályozó berendezés segítségével elválasztják a csonthéjat a terméstől.

Suspected harmful effects

Feltételezhetően nincs káros hatása

Would it be suitable for soil reclamation in general?
Yes
Justification, references

Magas makro- és mikroelem tartalmának köszönhetően alkalmas tápanyagpótlásra. Mivel javítja a talaj szerkezetét és tápanyagtartalmát, ezáltal növeli a terméshozamokat.

Would it supply nitrogen, phosphorous and/or potassium to the soil?
Yes
Justification, references
Would it supply mesoelements (Ca, Cl, Fe, Mg, Na, S, Si) to the soil?
No information
Would it supply microelements (B, Co, Cu, Mn, Mo, Zn, V) to the soil?
No information
Would it provide sufficient amounts of special nutrients to the soil?
No
Would it increase the humus/organic matter content of the soil?
Yes
Justification, references

Magas szerves anyag tartalma miatt igen.

Would it suffice as a main component of growing media?
No
Would it suffice as an additive to growing media?
No information
Would it improve the structure of compacted soil and/or contribute to soil crumb formation of poorly structured soils?
Yes
Justification, references

Talajlazítás céljából a talajba keverhetjük. Összeaprítva könnyebben biodegradálódik, a talajba keverve növeli a szerves anyag tartalmat, ez által hozzájárulhat a szerkezeti humusztartalom növekedéséhez, ami javít a tömörödött talajokon.

Would it be suitable for physical stabilisation and/or texture improvement of loose, quagmire soils?
No
Would it be suitable for amending sandy soils?
Yes
Justification, references

Aprítás után a szerkezeti humusztartalom növelésén keresztül nem elképzelhetetlen ilyen irányú felhasználása.

Would it be suitable for erosion prevention?
No information
Would it be suitable for amending acidic soils?
No
Would it be suitable for amending saline and sodic soils?
No
Would it reduce the mobility and availability of the contaminants?
Yes
Justification, references

Jó szorpciós tulajdonságának köszönhetően kiváló a szennyezőanyag megkötő képessége. Szénhidrogének és nehézfémek eltávolítására alkalmas.

Would it intensify the mobility, availability of the contaminants?
No information
Would it intensify physical, chemical, and/or biological degradation and decomposition of contaminants?
No information
Would it be suitable for production of geotechnical elements?
Yes
