National Recycling Figures

About 31.7Mt (58.7%) of materials were processed for recycling. The three largest fractions, making up a combined three-quarters of the total, were masonry materials (12.3 Mt), organics (7.3 Mt) and metals (5.0 Mt). C&D materials represented the largest source stream (43%). Over the 11-year timeframe, recycling of C&D waste grew by 3.4 Mt or 34% (13% per capita), the most of any of the streams. Demolition waste recycling is a success story in most jurisdictions, providing an alternative source of materials for road base and construction aggregates.
