Benefits of Wool

Sheep and lambs in a paddock resting.Although wool has been used for tens of thousands of years, wool is a unique material that hasn't been replicated by modern technology. It's properties vary greatly and in many different, useful areas.

LAB ANALYSIS OF WOOL PELLETS:

Lab results of EcoWool Pellets

 

Here are  few highlights:

  • Wool garments actively generate heat when taken from warm indoor environments into the cold and wet of the outdoors in winter. a
  • Wool can be regarded as an ‘active’ fibre; it is able to absorb and desorb moisture vapour as conditions around it change. This process is a form of equilibrium reaction.a
  • A property known as hygroscopicity. Wool absorbs almost 35% of its dry mass at 100% humidity, which is more than any other fibre. a
  • Wool is a natural protein made up of amino acids that provides wool with the ability to bind with several toxicants in air including pollutants cited as health hazards in air are sulphur dioxide (SO2), formaldehyde and nitrogen dioxide (NO2). Sulphur dioxide and nitrogen dioxide are byproducts of combustion processes involving fuels such as petroleum products and coal, and are produced by domestic appliances, open fires and vehicle exhausts.a
  • Microbes and insects can digest wool and under favourable temperature and humidity conditions, more than 104 viable bacteria and 103 fungi per g of wool develop and cause biodegradation (Gochel etal.,1992).b
  • Wool can absorb up to 30% moisture of its own weight with coarse wool acting as a water conservation medium. (Kadam et al., 2013).
  • Wool suppresses weed growth and acts as a source of N,and lasts longer than other mulch materials. Wool absorbs liquids, releasing them slowly into the soil.b
  • McNeil et al. (2007) found suitability of wool wastes as fertiliser with elevated levels of essential elements such as N (19%), S (19%) and Mg (7%) in the grass grown on wool fertilised plots as compared to the control.b
  • Coarse wool provided significantly higher quantity of available nitrogen, phosphorus and potash for plants. (Kadam et al., 2014). Another advantage, wool soaks up in the soil, it fluffs up and expands, increasing soil porosity and improving the soil's ability to retain oxygen (Kadam et al., 2014; Hargreaves, 2017).b
