Process waste is recycled into wood chips for pulp and paper manufacturing or mulch. The raw material (logs) that are used in the manufacture of Anbrook shakes and shingles are sourced from International Forest Products, who is an active member of the Sustainable Forestry Initiative Program. This ensures that the raw material is harvested in an environmentally responsible manner, and that the forests are being managed sustainably for future generations. For more information about this important program, please go to www.aboutsfi.org. Shingles are shipped in a biodegradable wrap.
