This study investigated the effects of the sawdust vermicompost extract (aqueous extract) on yield and chemical quality of Dracaena marginata var.‘Tricolor’ grown under four sawdust vermicompost extract solutions (0, 250, 500 and 1000 ppm). The sawdust vermicompost extract was prepared using non-aerated extraction methods with 1:10 (v/v) of sawdust vermicompost to water and was sprayed three ti...

Thermochemical conversion of biomass waste is a high potential option for increasing usage renewable energy sources and transferring wastes into the circular economy. This work focuses on evaluation energetic adsorption properties solid residue (char) gasification process. Gasification experiments (wheat straw, hay pine sawdust) were carried out in vertical fixed bed reactor, under CO2 atmosphe...

Abstract Petung bamboo (Dendrocalamus asper) stem-based hematite-biochar composite (HBC) has been synthesized using microwave-assisted pyrolysis (MAP) to replace conventional pyrolysis. The sawdust contains 19.8-26.6% lignin and cellulose as much 4.24-5.36% so that it can be used precursors in biochar preparation. In general, bamboo-based a low adsorption capacity. this study, was modified by h...

Pineapple rind is a by-product of the pineapple processing industry and contains nutrients and other compounds which must be utilized as a bioresource for socio-economic benefits while preventing the potential problems of improper agroindustrial biomass disposal methods. Pleurotus ostreatus is an edible oyster mushroom with medicinal properties and can be cultivated on various agroindustrial bi...

The present study was undertaken to observe the chemical composition of different types of sawdust available in the urban and peri-urban areas of Chittagong, Bangladesh. Twenty different types of sawdust from different plants were collected from study areas. Chemical analyses of the samples were carried out in triplicate for moisture, dry matter (DM), metabolizable energy (ME), crude protein (C...

The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds. The purpose of this work was (1) to develop a method to measure emissions from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbo...

Heavy metals released into the surface and ground water has been a major preoccupation for many years because of their increased discharge, acute toxicity, non-biodegradable nature and tendency for bioaccumulation [1-3]. Iron a common contaminant enters the water bodies through effluents of industries such as electroplating, mining, steel processing etc. The presence of Fe (II) in water results...
