Alternatives To Wood Pulp
See also: Tree-free paper and Fibre cropToday, some people and groups advocate using field crop fibre or agricultural residues instead of wood fibre as being more sustainable. However, wood is also a renewable resource, with about 90% of pulp coming from plantations or reforested areas. Non-wood fibre sources account for about 5-10% of global pulp production, for a variety of reasons, including seasonal availability, problems with chemical recovery, brightness of the pulp etc. Non-wood pulp processing requires a high use of water and energy.
Nonwovens are in some applications alternatives to paper made from wood pulp, like filter paper or tea bags.
