The actor and environmental activist Woody Harrelson is putting his support behind the construction of a $500 million tree-free paper mill in Canada which would produce straw-based paper. Prairie Pulp and Paper, the company behind the project, already produce a copy paper which is 80 per cent waste wheat straw. According to a study they commissioned this paper has a lower environmental impact than 100 per cent recycled paper. However, a representative of the Forest Products Association of Canada thinks wheat paper will be a niche product due to limited availability of waste wheat and the need for the strength and quality in paper that is provided by wood fibres.
