Peat forms when plant material, usually in wet areas, is inhibited from decaying fully by acidic and anaerobic conditions. It is composed mainly of wetland vegetation: bog plants including mosses, sedges, and shrubs. Approximately ninety five percent of the moss peat volume is pores. Smaller pores are filled with water, while the larger ones are filled with air. Peat deposits are between six to twelve thousand years old and accumulate slowly, at the rate of about one millimeter per year. Extracting and treating peat in a specific way, it is possible to obtain a wide range of innovative materials—paints, fillers as well as composite materials.
