The aim of this paper is to find out new alternative materials that respond to sustainable development criteria. For this purpose, an original utilization of straw for the design of lightweight aggregate concretes is proposed. Four types of straw were used: three wheat straws and a barley straw. In the present study, the morphology and the porosity of the different straw aggregates was studied ...

Straw mushrooms were grown on lead contaminated rice straw and stubble. Study materials were dried, acid digested, and analyzed for lead using flame atomic absorption spectrophotometry. The results showed the highest lead concentration in substrate was 445.350 mg kg⁻¹ in Treatment 3 (T3) and the lowest was BD (below detection) in Treatment 1 (T1). The maximum lead content in straw mushrooms was...

Bovine ruminal contents and blood were ensiled with wheat straw, either untreated or treated with 4% NaOH (DM basis), with and without addition of 5% dry molasses. Proportions of ruminal contents, blood, and straw were 45:15:40, wet basis, respectively. Wheat straw also was ensiled alone, and water was added to attain 43% DM. After 60 d, all silages had a desirable aroma. The pH of the ensiled ...

Crab waste preserved with .2% NaOCl was mixed with wheat straw, liquid molasses, and water (32:32:16:20, wet basis) and ensiled for a minimum of 8 wk with microbial inoculant. A reduction in pH and water-soluble carbohydrates (WSC) and a higher concentration of lactic acid (4.9%, DM basis) were achieved. The trimethylamine (TMA) concentration in the silage was 11.2 mg N/100 g. In a digestion tr...

Abstract—Rice straw pellets are a promising fuel as a renewable energy source. Financial analysis is needed to make a uti lization system using rise straw pellets financially feasible, considering all regional conditions including stakeholders related to the collection and storage, production, transportation and heat utilization. We conducted the financial analysis of feasibility for a heat uti...

The effects of atmospheric pressure dielectric barrier discharge (DBD) plasma on the surface properties of wheat straw were investigated in this work. The surface wettability changes in the wheat straw were determined using contact angle measurements, the surface morphology was observed using scanning electron microscopy (SEM) and atomic force microscopy (AFM), and the chemical characteristics ...

A two-year field study was conducted to investigate the performance of a lightweight trash-board moldboard plow (with and without a trash-board), as influenced by stubble height and water content. Both fields were measured for the performance of a trash-board moldboard plow when used during the optimization of the plowing depth, the water content, and the reaction forces. The results showed tha...

The decision on the location of a straw-based power generation plant has a great influence on the plant’s operation and performance. This study explores traditional theories for site selection. Using integer programming, the study optimizes the economic and carbon emission outcomes of straw-based power generation as two objectives, with the supply and demand of straw as constraints. It provides...

Pleurotus ostreatus (MTCC142) was cultivated on three different agro wastes viz: Wheat straw, Soybean straw and Chick pea straw. Total antioxidant, reducing power and total phenolic content effect of the extracts was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and Folin-Ciocalteu method. The aqueous extract of P.ostreatus cultivated on soybean straw exhibited good antioxidant acti...
