Initial Research
• Fallen leaves, considered "landscape waste" are:– left to form mulch– OR gathered and decomposed to create compost– OR collected with other landscape waste and
garbage• takes up valuable landfill space• removes nutrients from the soil• create greenhouse gases when burning
• Why not use this abundant resource to substitute materials and create cheaper, greener products?
