The evaluation of selected mechanical and physical properties of pelletized compost

Original language description

The production of compost and its use on agricultural land is now widespread and well known. With regard to the conditions of the changing climate (temperature fluctuations, unbalanced precipitation, etc.) and anthropogenic activities associated with soil degradation and environmental devastation, issues related to wider use of compost are being addressed within Europe. Special attention is paid to innovative modifications of compost into fertilizers with improved properties. A promising solution is also offered by the production of pellets from compost. The pellets have better utility properties, are easier and more accurately metered, and therefore it is easier to supply the required amount of organic matter to the soil. For the needs of experimental measurements carried out in 2021, connected with pelletizing, 3 variants of input raw materials were selected. These are compost itself, compost in combination with biochar and compost in combination with grape marc. Afterwards, selected mechanical-physical properties, such as bulk density (845-1 056 kg/m3), mechanical durability (85.1- 97.3%) and compressive strength (16.3-18.4 MPa) of pellets samples were evaluated. The obtained results confirmed a statistically significant difference between the evaluated samples. In particular, the results of mechanical resistance indicate their qualities. These results may ultimately be useful in eliminating risks in mechanical distribution systems, in dust generation, and in handling, applying or storing.
