Concentrated visitor activity in mountain areas generates significant amounts of both solid waste and wastewater, which can pollute water and soil through improper storage and disposal. Solid waste can build up from food and beverage consumption and the disposal of used packaging, supplies and equipment.
Projects that minimize trash generation and help ensure responsible disposal of both rubbish and human waste are encouraged in this category.
