Question

how we can use a straw as a resource

Answer 1

Rice straw can either be used alone or mixed with other biomass materials in direct combustion, whereby combustion boilers are used in combination with steam turbines to produce electricity and heat. The energy content of rice straw is around 14 per kg at 10 percent moisture content. The by-products are fly ash and bottom ash, which have an economic value and could be used in cement and/or brick manufacturing, construction of roads and embankment etc.

Straw fuels have proved to be extremely difficult to burn in most combustion furnaces, especially those designed for power generation. The primary issue concerning the use of rice straw and other herbaceous biomass for power generation is fouling, and corrosion of the boiler due to alkaline and chlorine components in the ash.

Answer 2

Animal feed

Straw has little calorific value but it is fed to domestic animals as part of the roughage component of the diet when they are on or near a maintenance level of energy requirement. Due to the risk of impaction and its poor nutrient profile, it should always be restricted to part of the diet. It may be fed as it is, or chopped into short lengths, known as chaff.

Basketry

Bee skeps (hives), baskets and other containers, furniture and matting are made from coiled and bound together continuous lengths of straw. The technique is known as lip work.

Bedding

The traditional straw-filled mattress, also known as a palliasse, is still used in many parts of the world.

It is commonly used as bedding for ruminants and horses. This bedding can then be composted after it has been replaced.
