RECENT HAPPENINGS IN THE GLOBAL WASTE HEAT RECOVERY SYSTEM MARKET

• In November 2021, Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC) received an order from Sendai City to renovate its Matsumori Waste-to-Energy Plant (plant for burning municipal solid waste). The refurbishment of the Matsumori Waste-to-Energy Plant is to extend its service life, save energy, and reduce carbon dioxide emissions by 8% annually.
• The Renovation of stoker-type and related equipment will increase heat recovery, combustion and operation stability, and power generation ability. 
• Siemens Energy and TC Energy Corporation agreed in February 2021 to construct an innovative waste heat-to-power pilot facility in Alberta, Canada. This innovative heat recovery is designed by Siemens and patented under Echogen Intellectual Property. This innovation helps capture waste heat from a gas turbine at pipeline compression and converts it into emission-free power. Heat recovery is based on an advanced Rankine Cycle and uses supercritical carbon dioxide (CO2) as the working fluid to convert waste heat into power.
