This study was conducted to evaluate the response of brinjal (Solanum melongena L.) with conventional, non-conventional organic source, industrial by-products combined with inorganic fertilizers. The treatments imposed were T1 – Control (100% RDF), T2-100% RDF + Municipal Solid Waste Compost @ 5 t ha-1, T3 – 100% RDF + Municipal Solid Waste Compost @ 10 t ha-1, T­4 – 100% RDF + Vermicompost @ 2.5 t ha-1, T5 – 100% RDF + Vermicompost @ 5 t ha-1, T6 – 100% RDF + Rice Husk Ash @ 5 t ha-1, T7 – 100% RDF + Rice Husk Ash @ 10 t ha-1, T8 – 100% RDF + Lignite Fly Ash @ 5 t ha-1, T9 – 100% RDF + Lignite Fly Ash @ 10 t ha-1. There were nine treatments combinations replicated thrice in CRD. The soil was sandy in texture with available nitrogen, phosphorus and potassium of 257, 10.2 and 117 kg ha-1 respectively which fell in fertility status of low. The soil classified taxonomically as Typic Udisamments. The results showed that application of 100% RDF + Vermicompost @ 5 t ha-1 (T5) significantly increased yield attributes viz., fruit length (16.6 cm), fruit girth (15.2 cm), no. of fruits plant-1 (20.67), fruit weight (45.2 g) and fruit yield plant-1 (934.2 g plant-1). This treatment registered maximum quality attributes like ascorbic acid content (4.5 mg 100 g-1), crude protein (4.81%), drymatter of fruit (70.2 g plant-1) and dry matter of plant (81.3 g plant-1). The post harvest soil available N (148mgkg-1) and P (7.15mgkg-1)status was higher due to application of 100% RDF with Vermicompst @ 5 t ha-1 (T5).  The post harvest available K (75.58mgkg-1) status recorded higher in the treatment T9 which received 100% RDF with Lignite Fly Ash @ 10 t ha-1 (T9).

The objective of this study was to optimize the parameters for the development of refused derived fuel (RDF) pellets from municipal solid waste (MSW) and rice husk by using Response Surface Methodology (RSM). In this a systematic study was conducted, where three parameters were varied according to RSM factorial design. The binder concentration (5-10%) pressure (700-1200 psi) and retention time (3-7 minutes) were used for RDF pellet development under hydraulic press, measured hardness bulk density (BD) and durability (DU). The T3 treatment results revealed the highest pellet hardness, bulk density, and durability 25 kg, 805 kg/m3, 99% respectively by application binder concentration (5%), pressure (1200 psi) and retention time (5 minutes). The experimental data on response variables were fitted into quadratic polynomial model using the multiple regression analysis and found that it was statistically significant quadratic model. The RDF physical chemical and mechanical characteristics were also evaluated and found their relationship between HHV, carbon, ash, DU, BD and energy density. The ash contents were inversely proportional to DU and HHV whereas DU was directly related to BD. Bangladesh J. Sci. Ind. Res.54(4), 329-338, 2019

<p>The oil palm empty fruit bunches are solid waste produced from the processing of oil palms which have a large amount of potential to be used as compost and are expected to improve the physical, biological and chemical properties of the subsoil. This study aimed to evaluate the best combination between oil palm empty fruit bunches compost and rice husk charcoal on soil chemical properties in tomato. This research was conducted in Sona Village, Labuhanbatu Regency on December 2019-March 2020. Analysis of soil chemical properties was conducted at the Socfindo Seed Production and Laboratories (SSPL) Laboratory of PT. Socfin Indonesia. The study was conducted with a factorial randomized block design with 2 factors. The first factor was the application of oil palm empty bunches which consists of no oil palm empty bunches (control), 0.5 kg/polybag, 0.7 kg/polybag and 1 kg/polybag. The second factor was the application of rice husk charcoal which consists of non-husk charcoal (control), consisting of 0.2 kg/polybag and 0.4 kg/polybag. Data that had a significant effect after analysis of variance continued with DMRT at the level of α = 5%. The results showed that application of oil palm empty fruit bunches (0.7 kg/polybag) significantly increased pH and C-organic. Application of rice husk charcoal (0.2 kg/polybag) significantly increased C-organic and P-available.</p>

In this study, experimental results on mesoporous zeolite preparation from a common solid waste, the rice husk ash by a top-down and bottom-up approach were reported. In top-down method, the consecutive treatments of zeolite by acid and alkaline in the presence of a cationic surfactant (CTAB) successfully generated mesopores in the zeolite. In bottom-up method, the sufficient added amount of CTAB in the gel composition could form mesopores in the zeolite. The obtained mesoporous zeolite possessed mesopore with a size of around 3-6 nm in both top-down and bottom-up approaches. As a result, the pore volume of the mesoporous zeolite was significantly increased by more than 60% when comparing to the “parent” rice-husk-ash derived zeolite. Significantly, the mesopore surface area of the mesoporous zeolite could be 2.4 times higher than that of the parent zeolite.
