- Straw is an
agricultural by-product, the dry stalks of cereal plants, after the
grain and chaff have been removed.
- Biomass is the
mass of living organisms and recently dead matter like wood, leaves,
stalks, straw and other organic matter.
- Wheat-straw waste
is a natural byproduct of the industrial fractionation of wheat
straw.
- This material
consists approximately 38% of cellulose, 20% of lignin, 20% of
xylose and a little of arabinose and ash. The total dry matter
reaches 24,3%.
- Wheat straw is
renewable, widely distributed, available locally, moldable,
anisotropic, hydroscopic, recyclable, versatile, non-abrasive,
porous, viscoelastic, easily available in many forms, biodegradable,
combustible, compostible, and reactive.
- Wheat straw is
one of the most abundant and cheap agricultural wastes, and it is
estimated that about 250 million tons are produced annually in
China. Wheat straw is predominantly disposed of by direct burning in
open field due to lack of effective utilization, which also causes
serious
environmental pollution.
- The processing of
straw differs from that of wood in the initial stage of the
composite material process . The harvested and baled wheat straw is
size-reduced (chopped), hammer-milled, screened, and pre-wetted
before defibration (the fiber-refining process)
- Many possible
composite products can be made using wheat fibers including
structural (using thermosetting resins) and nonstructural (using
either a thermosetting or thermoplastic resin) materials,
geotextiles and molded products (using fiber mats prepared by
physical
entanglement, nonwoven needling, or thermoplastic fiber-melt matrix
technologies), sorbents and filters (for removing pollutants from
contaminated air, water, and/or soil), packaging, and in products in
combination of other resources.
- Compressed
agricultural fiber (CAF) is manufactured from wheat or rice straw,
the byproduct of wheat and rice grain, and has been successfully
used for many years in the general construction trade.
- Bioethanol is
made from biomass and it is renewable. Wheat straw is a good raw
material for ethanol production, since wheat straw has a rather high
content of cellulose.
- Straw has a
higher ash content and lower lignin content when compared with wood
and has not been used for board manufacture with the use of
conventional formaldehyde resins (UF, MUF, PF, etc.), while other
types of adhesives like polymeric isocyanates.
- Agricultural
residues (straws) are primarily composed of cellulose, lignin and
hemicelluloses. But straws also contain significant amounts of
pectins, proteins and, most importantly, inorganic compounds (ash),
most of which is silica.
- Wheat straw pulp
will likely be used in blends with wood pulps in proportions
consistent with paper and board cost and performance specifications.
- The bioconversion
of the agro waste material into fuel has received considerable
interest during recent years.
- Currently a most
important application of cellulases and hemicellulases in the pulp
and paper industry is the biobleaching of pulp, the production of
dissolving pulp, the treatment of wastewater and the deinking of
recycled waste paper.
- Wheat straw is
produced about 33-48 mons/acre and crop to residue ratio is 1:1.
40-50% wheat straw is being used to feed animals by the farmers and
landlords and 44-56% is surplus and is being sold into the market at
the rate of Rs. 90-100/Mon
