  • Willow biomass is an environmentally sound, locally produced, renewable source of energy and bioproducts.
  • Willows are easily propagated from unrooted cuttings. High yields can be obtained in a few years. Willow’s genetic diversity and short breeding cycle can be utilized to produce improved varieties. Willows vigorously resprout after each harvest. The amount of heat in a dry ton of willow is similar to other hardwoods. An array of bark and foliage colors creates opportunities for visually stunning landscape designs.
  • low biomass crops increase habitat diversity. They are planted on open, agricultural land, not on cleared forest land. A crop can be harvested six to seven times before replanting is required 1 ST HARVEST 3 YEARS . Willow cultivation uses significantly fewer pesticides than traditional agriculture.
  • One hectare of a well-managed willow plantation can yield 10 - 12 tonnes of dry matter per year, with energy equivalent to about 5 000 litres of oil.
  • As a rough guide, 1 kg of willow will yield about 1 kWh of electrical output. A district heating scheme for a development of 100 houses would require about 25 hectares of willow coppice. A combined heat and power system with 100 kW electrical output will use 50 ha of willow coppice harvested on a three year cycle. A power station generating 5 MW of electricity would need around 2 500 ha of willow.
  • converting willow into energy: combustion is used for heating water or to raise steam for a turbine; gasification produces a combustible gas that can be burned in a boiler, or used as fuel for an engine or gas turbine; pyrolysis can be used to convert the crop into gas, oil or charcoal fuels.
  • They reduce the need for fossil fuels for energy, chemicals, products, and fuels. Combustion of willow biomass releases fewer acid-rain producing compounds into the atmosphere Willow crops reduce soil erosion and nonpoint source pollution Willow crops generate income for local landowners and create jobs within the local community.
  • Riparian buffers - Natural barriers that prevent chemicals from entering streams, ponds, and lakes. Phytoremediation - Willows clean up toxins from contaminated sites. Living snowfences - Strategically planted willows trap drifting snow. Wastewater management - Willows filter contaminants from wastewater.
