General information about the waste or by-product
- 02 WASTES FROM AGRICULTURE, HORTICULTURE, AQUACULTURE, FORESTRY, HUNTING AND FISHING, FOOD PREPARATION AND PROCESSING
- 02 01 wastes from agriculture, horticulture, aquaculture, forestry, hunting and fishing
- 02 01 03 plant-tissue waste
Residue of wheat harvesting. Straw is an agricultural by-product, it is the dry stalks of cereal plants, after the grain and chaff have been removed. Straw makes up about half of the yield of cereal crops.

Main characteristics of the waste/ by-product
Raw fiber, proteins, lipids, nutritional elements.
Partially or fully mineralised components can be introduced into the element-cycles by microbial and plant use. The nonmineralised part can take part in humus formation. Directly mixed into the soil we introduce high C/N ratio organic material, which leads to the accumulation of carbon respirating bacteria, and the build up of low N content into the temporary cells. This process results accessable N for plants. The N content of the microorganisms is released after their death, when the straw is consumed. If our aim is nutrition supplement, the straw should be mixed into compost or manure and together it is biodegraded by the microorganisms. If our aim is soil loosening, or the increase of humus content, the straw should be mixed into the soil directly. In this case we have to calculate with the change of the soil’s biological sructure.
Physico-chemical properties of the waste or by-product
Total organic content: 8.3%; N: 0.62%; P:0.07%; K:0.79%; Ca: 0.21%; Protein: 3.9%; Raw fiber: 36.9%; Lipid: 1.5%
In mushroom compost as the base material; energetical utilization, animal feed, basketry, bedding: humans or livestock, biofuels, biomass, construction material, thatching.
Hazards of the waste or by-product
Directly mixed into the soil high C/N ratio organic material is introduced to the soil, which leads to the accumulation of the carbon-respirating bacteria. In this case we have to calculate with the change of soil microbiodiversity.
Potential utilisation in soil
Thanks to its high organic material content, wheat straw can be used for soil improvment.

Straw bales are sometimes used for sediment control at construction sites. However, bales are often ineffective in protecting water quality and are maintenance-intensive. For these reasons the U.S. Environmental Protection Agency (EPA) and various state agencies recommend use of alternative sediment control practices where possible, such as silt fences, fiber rolls and geotextiles.

In many parts of the world, straw is used to bind clay and concrete. A mixture of clay and straw, known as cob, can be used as a building material. There are many recipes for making cob.
When baled, straw has moderate insulation characteristics (about R-1.5/inch according to Oak Ridge National Lab and Forest Product Lab testing). It can be used, alone or in a post-and-beam construction, to build straw bale houses. When bales are used to build or insulate buildings, the straw bales are commonly finished with earthen plaster. The plastered walls provide some thermal mass, compressive and ductile structural strength, and acceptable fire resistance as well as thermal resistance (insulation), somewhat in excess of North American building code. Straw is an abundant agricultural waste product, and requires little energy to bale and transport for construction. For these reasons, strawbale construction is gaining popularity as part of passive solar and other renewable energy projects.
