Municipal Organic Solid Waste

The study was conducted to determine the performance of vermicompost and conventional aerobic compost produced from municipal organic solid waste used in Amaranthus viridis production during the period from October 2014 to June 2015 at the Horticulture Research Centre of the Bangladesh Agriculture Research Institute, Gazipur, Bangladesh. In this study, three compost varieties (vermicompost, conventional aerobic compost, combination of vermicompost and conventional compost) and three levels of compost treatments (0, 100 and 150 g/m2) with three replications were applied. The plots were arranged in randomized complete block design. Vermicompost was prepared by using Eisenia fetida. Different composts (vermicompost and conventional aerobic compost) and plant sample were taken first for chemical and physical analysis to find out the effect of these composts on the growth of amaranth. The result of the study showed that different compost varieties significantly affected the chlorophyll content, dry matter content, height per plant, numbers of leaves, weight per plant, nitrogen, calcium, magnesium, potassium, total phosphorus positively in favour of vermicompost application and sulphur content, sodium, moisture content in conventional aerobic compost application. Vermicompost application showed higher result for growth and yield indices and nutrient content compared with conventional aerobic compost.J. Environ. Sci. & Natural Resources, 9(2): 43-49 2016

Municipal Organic Solid Waste

The experiment was conducted with the objective of providing more information on the physiology and rumen microbial ecology of goats fed municipal organic solid waste treated with Diastic microbes of snails (Achatina achatina). The study was on the treated and untreated municipal organic solid waste as components of experimental diet. Balanced rations containing diets; A = 45% untreated municipal organic waste (UMOW), B = 45% treated municipal organic waste (TMOW), and C = 70% treated municipal organic waste (TMOW), with wheat offal, palm kernel cake, and molasses used to balance the diets. Where grass/legume ratio of 3 parts of Panicum maximum and 1 part of Centrocema were fed across treatments at the same proportion. The three rations were fed to 18 unsex Red Sokoto goats aged between 6 to 7 months, with an average weight of 8.01±2.50kg. They were housed in pens, on a floor space of 0.5 to 0.75m2 in a completely randomized designed experiment replicated six times and fed for a period of 52 days. The results were separated according to the parameters of rumen physiology (pH, total volatile fatty acids, acetic, propionic, butyric acids and ethanol, and rumen ecology (bacteria, protozoa, and fungi, which are mainly anaerobic microbes). The investigations revealed that microbial (bacteria, protozoa and fungi) load counts were significantly (p<0.05) influenced by dietary treatments. While the total volatile fatty acids (TVFA), acetic, butyric and propionic increased (p<0.05) except for the TVFA and the propionic acid that showed numerical (p>0.05) increased levels of (TMOW). The pH levels improved (p>0.05) between 6.7 to 6.8 where the rumen electrolytes (Ca, Na and K) increased (p<0.01) with increased levels of TMOW. Rumen moisture, dry matter and fat content were (p<0.01) influenced by TMOW diets while ash content was (p<0.01) influenced by the TMOW. Crude protein, ether extract, crude fibre and carbohydrate were not affected (p<0.01; p<0.05) affected. It is good to note that, the microbial community of snail used in the pre-feeding fermentation of municipal organic waste had influence in the physiology and rumen microbial ecology at interface with the goat, enhanced improved the organic matter degradation and feed quality, of the highly fibrous municipal organic solid waste.
