“…Various factors may, however, contribute to the quality of FW compost as the sources of FW vary by their heterogeneous compositions, sources, and the eating habits of 1 3 consumers (Cerda et al 2018). Several studies have concluded that when FW compost is applied as soil additive, it promotes plant growth and improves biomass and nutrition provision (Choy et al 2015;Ronga et al 2016;Kaur et al 2017). Nevertheless, the quality of the food compost produced depends on various factors, such as moisture content, carbon and nitrogen ratio, aeration, porosity, bulk density, and organic matter (Azim et al 2018;Waqas et al 2018).…”

Purpose Utilization of food waste as composting materials offers a sustainable solution to manage waste and reduce reliance on fertilizers. Method This study is focused on the efficiency of food waste compost and the effect of the addition of magnetite (Fe 3 O 4 ) nanoparticles on the growth and heavy metals uptake by roselle (Hibiscus sabdariffa) for the cultivation period of 127 days. Five different treatments were applied, namely soil (S), food waste compost (F), a mixture of soil and Fe 3 O 4 (SM), a mixture of soil and food waste compost (SF), and a mixture of soil, food waste compost, and Fe 3 O 4 (SFM). Results After 127 days of cultivation, the plant height averaged at 803 mm with 26 leaves produced across all treatments. Total leaf area, fruit production, and biomass yield were different (P < 0.05) among the treatments. Roselle crops grown under soil and food waste (SF) media produced the highest yield (12.15 g/plant), the most number of fruits (11 fruits/plant), and the highest leaf area (1200 cm 2 /plant). The accumulation of heavy metals in plant tissues was lower than the toxicity levels. There was no difference in the heavy metal content in all growing media, except for Ni, Mn, and Pb. Roselle crops applied with Fe 3 O 4 showed no difference (P > 0.05) from its control (without Fe 3 O 4 ) in relation to growth performance. Conclusion The findings of this study showed that food waste can be applied in composting to promote plant growth. Therefore, it can be considered as a substitute for chemical fertilizers. Meanwhile, the application of Fe 3 O 4 appeared to be experimental-condition dependent.
