Sustainable Bio-Conversion of Rice Straw Waste into High Quality Organic Fertilizer

Biotechnology for aerobic conversion of food waste into organic fertilizer.

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...

Utilization of different waste proteins to create a novel PGPR-containing bio-organic fertilizer

High-quality bio-organic fertilizers (BIOs) cannot be produced without the addition of some proteins, while many waste proteins are haphazardly disposed, causing serious environmental pollution. In this study, several waste proteins were used as additives to assist with the reproduction of the functional microbe (Bacillus amyloliquefaciens SQR9) inoculated into matured composts to produce BIOs....

Catalytic conversion of waste low density polyethylene into fuel oil

Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...

The effect of bio and liquid organic fertilizer on weight and quality of apple

This research aimed to analyse the effect of biopesticide and organic liquid fertilizer on weight and quality of apple. The study was carried out in Bumiaji, Batu, East Java (805'S, 11280'E, 1400 m in altitude) on July December 2013. The liquid organic fertilizer (LOF) was produced from water mixed with nitrogen source such as manure, urin, legume leaves, phosphoric powder and an energy sourc...
