Washington, Nov 25: A team of scientists has suggested that growing plants and trees on top of a landfill, a process known as ‘phytocapping’, could reduce the production and release of harmful greenhouse gases like methane and carbon dioxide (CO2).
Despite legislative pressures to reduce landfill use, in certain parts of the world, it remains the most economical and simplest method of waste disposal.
Biodegradation of organic matter in a landfill site occurs most rapidly when water comes into contact with the buried waste, according to Kartik Venkatraman and Nanjappa Ashwath of the Department of Molecular and Life Sciences, at Central Queensland University
