| Summary: | Composting is a good recycling method to fully utilise all the organic wastes present in kitchen waste due
to its high nutritious matter within the waste. In this present study, the optimised mixture proportions of
kitchen waste containing vegetable scraps (V), fish processing waste (F) and newspaper (N) or onion peels
(O) were determined by applying the simplex-centroid mixture design method to achieve the desired initial
moisture content and carbon-to-nitrogen (CN) ratio for effective composting process. The best mixture
was at 48.5% V, 17.7% F and 33.7% N for blends with newspaper while for blends with onion peels,
the mixture proportion was 44.0% V, 19.7% F and 36.2% O. The predicted responses from these mixture
proportions fall in the acceptable limits of moisture content of 50% to 65% and CN ratio of 20–40 and were
also validated experimentally. |
