Agricultural waste fibers have been found to be suitable as reinforcement in cement-based composites, but studies on oil palm fiber as reinforcement in gypsum-cement wall panels are scarce. A mixture of two equal weights of gypsum and cement, with water-binder ratios of 0.45 and 0.55 were prepared. In each mix a varying percentage of fiber contents of 2%, 3% and 4% by weight of the binders were...

Dynamic TG analysis under nitrogen was used to investigate the thermal decomposition processes of 10 types of natural fibers commonly used in the polymer composite industry. These fibers included wood, bamboo, agricultural residue, and bast fibers. Various degradation models including the Kissinger, Friedman, FlynneWalleOzawa, and modified CoatseRedfern methods were used to determine the appare...

This paper studies the addition of fibers from end-of-life tires to commercial mortar mixtures. Two different types of mortar, one lime-plastic and other cement-fluid, are mixed with different percentage of fibers ranging from 0% to 1%. The changes in bulk density, consistency, compressive and flexural strength, dynamic Young modulus and water absorption are studied. According to the results, c...

Economic growth inevitably influences the food chain. Growing demand with changes in lifestyle and health consciousness encourage use of packaged and pre-prepared foods. The needs of environmental protection from waste generated are largely overlooked, and a lack of knowledge about the impact on the environment and its health effects constitute food security/safety problems. Food production and...

The waste water showed high values of total solid (TS), hardness and chloride with slightly alkaline pH along with high concentrations of Cr (2.03 mg l(-1)), Ni (1.59 mg l(-1)) and Zn (0.46 mg l(-1)). The concentration of Cu (0.21 mg l(-1)) and Zn in industrial waste water was low than Ni and Cr. The diluted (25 and 50%), undiluted (100%) waste water was used to irrigate the lettuce plants grow...

As per the estimates of World Health Organization (WHO) about 80% of world’s population depends on plant and plant products for their primary healthcare. Recently the demand for herbal drugs has increased many folds at the global level, as these herbal medicines do not have any side effects and its cost effectiveness. Huge quantities of solid waste is generated during the production of decoctio...

Fiberboards are used in a variety of applications that can be for interior as well exterior. However, their production involves the consumption virgin wood fibers and use formaldehyde-based adhesives, with consequent impact on environment health. The removal these adhesives results significant loss physico-mechanical properties. To confront major problems, wheat straw, an agricultural waste, ra...

      Background and aims   Rapid population growth, industrial development, urbanization culture propagation and excessive material consumption are the most important factor which caused over increasing of municipal, industrial and agricultural waste in human society. Inappropriate disposal of generated waste in recent years created several environmental menace and crisis in human society.   m...

Agricultural Census data is summarised over spatially course reporting units for reasons of farm confidentiality. This is problematic for research at a local level. This paper describes an approach combining dasymetric and volume preserving techniques to create a national land use dataset at 1km resolution. The results for an English county are compared with contemporaneous aggregated habitat d...
