The global waste-to-energy (WTE) market will reach $7.4 billion in 2013, according to a new study.

Driving the international growth in new WTE facility construction will be other waste management challenges, including unsustainable landfilling, methane emissions reduction, growing waste volumes and lack of space, according to a news release on a new 139-page report by London-based Visiongain.

The study acknowledges that WTE is more expensive than low-cost landfills, and therefore an increasing amount of governments are offering incentives or creating regulations to drive it forward.

The report provides insight into key drivers and restraints concerning WTE project developments, as well as identifying leading companies.
