Abstract

Abstract. The aim of this study is to highlight the main qualitative parameters of agricultural residues specific to the Republic of Moldova. The issue of research refers to the estimate of the possibilities of using indigenous agricultural
residues as a raw material for the production of biobriquettes in accordance with ENPlus international standards. In this study, fruit tree and vine pruning residues and residues from the main herbaceous crops (wheat, barley, oat,
maize for grain and sunflower) were evaluated for the following parameters: moisture content, calorific value, ash content and unitary conversion factor (ratio between residue mass and base yield mass of the respective crop). It has
been demonstrated that arboricultural and vines residues can be used as a raw material for the production of ENPlus certified biobriquettes, and herbaceous residues can be used only in mixtures with other types of vegetable biomass.


Key words: Biobriquettes; Arboricultural residues, Moisture content; Calorific value; Chemical analysis; Unitary conversion factor.


Rezumat. Scopul acestui studiu este evidenţierea principalilor parametri calitativi ai reziduurilor agricole pentru energie specifice Republicii Moldova. Problema cercetării se referă la estimarea posibilităţilor de folosire a reziduurilor
agricole indigene în calitate de materie primă la producerea biobrichetelor cu caracteristici în acord cu normele internaţionale ENPlus. În acest studiu au fost evaluate reziduuri provenite din tăierea pomilor şi a viţei de
vie şi reziduuri de la principalele culturi erbacee (grâu, orz, ovăz, porumb pentru boabe şi floarea soarelui), conform parametrilor următori: conţinutul de umiditate, valoarea calorifică, conţinutul de cenuşă şi factorul unitar de conversie
(raportul dintre masa reziduurilor şi masa producţiei de bază a culturii respective). S-a demonstrat că reziduurile agricole arboricole şi cele de viţă-de-vie pot fi folosite în calitate de materie primă la producerea biobrichetelor certificate
ENPlus, iar reziduurile erbacee pot fi utilizate doar în amestecuri cu alte tipuri de biomasă vegetală.


Cuvinte-cheie: Biobrichete; Reziduuri agricole; Conţinut de umiditate; Valoare calorifică; Analiză chimică; Factor unitar de conversie.
