There is a growing interest in adsorbents of natural origin that are renewable, effective, and able to treat water contaminated by oil products. The current paper investigates a novel biobased ‘peat - spent coffee grounds’ SCG-HP bio-based composite pellets as a perspective adsorbent for spilt oil products. The preparation and characterisation of SCG-HP bio-based composite material in pellet form is described. This research used homogenised peat (HP) as an efficient, natural binder. The SCG in different proportions (from 12 wt% to 50 wt%) with HP were used for the different types of SCG-HP granulated sorbents. The granule size obtained ranged from 2 to 6 mm with a total porosity of 56–61%. The sorption of the test oil (fresh engine oil Pilot 10W-40 SJ/CF) was investigated. Sorption studies showed maximum adsorption (capacity) from 90 to 125 wt% for SCG-HP granules.
