Waste to Energy (WtE) is the process of energy generation from the treatment of waste. Municipal solid wastes, process wastes, medical, and agricultural wastes are used for energy generation. The waste consists of both biomass and non-biomass materials such as paper & paperboard, food waste, plastic, glass, and metal. Waste to Energy also aids in waste management as it reduces the amount of wastes ending up in landfills.
The major drivers for the growth of waste to energy market include the increasing popularity of renewable energy resources, high waste generation, stringent regulations regarding waste disposal, and world policy regarding climate change such as the Kyoto Protocol and Paris Climate Agreement. The restraining factors for the growth of the market include low fossil fuel prices, which can be attributed to an oversupply of crude oil and gas due to increased production from shale reserves in the U.S. The availability of low cost feedstock has significantly reduced the costs of production of conventional plastic.
Global Waste to Energy Market Taxonomy:
By Waste Type:
- Municipal Solid Waste
- Process Waste
- Medical Waste
- Agricultural Waste
- Incineration or Combustion
- Anaerobic Digestion
- Landfill with Gas Capture
- Microbial Fuel Cell
- Electricity Generation
- Heat Generation
- Combined Heat and Power
- Transport Fuels
Waste to energy can be achieved by utilization of chemical (esterification), bio-chemical or thermo-chemical technologies. The use of these technologies is decided based on numerous factors, which include the composition and type of waste, calorific value, and the final energy form. The energy generated is utilized for applications such as electricity and heat generation, which is predominantly achieved by incineration. Transport fuels such as ethanol, bio-diesel, and bio-jet fuel are produced by processing waste. Increased blending of ethanol to gasoline is expected to bolster market growth for ethanol generation.
Global Waste to Energy Market Outlook:
- According to World Bank estimates, the world’s waste generation is projected to nearly double in volume by 2025 to reach 6 Mn tons of waste per day. The Organization for Economic Co-operation and Development (OECD) member economies accounted for approximately half of the world’s waste in 2016. However, waste generation is primarily expected to be driven by emerging economies in Latin America and Asia Pacific in near future due to growing consumption of plastics across applications such as packaging, construction and consumer goods. Also, a growth in developing economies’ waste production is expected to have a positive impact on waste to energy market as governments introduce new policy. Government of India’s target for sustainable energy generation of 175 GW by 2022 will include 10 GW capacity from waste to energy facilities.
- Europe is projected to be the largest market for WtE technologies over the forecast period. High generation of industrial waste, coupled with stringent EU-wide waste legislation has led to accelerated market growth in the region. West European economies have led the region in terms of existing and new capacity additions. For instance, Sweden incinerated 49.5% of its total municipal waste in 2015 for heat and power generation.
- Asia Pacific is projected to be the fastest growing market led by Japan and China. According to the World Energy Council statistics, Japan incinerated up to 60% of its solid waste for heat generation. Also, China doubled its WtE capacity between 2011 and 2015. In India, the NTPC Ltd. invited tenders from national and international companies in 2017 to set up 100 new waste to energy facilities across the country. This can be attributed to stringent regulatory policies pertaining to waste generation and disposal.
In October 2017, Wood Group announced the acquisition of Foster Wheeler. The acquisition allows Wood Group to strengthen its renewable energy business portfolio. Major players operating in the waste to energy market include Austrian Energy & Environment Group GmbH, Arrow Ecology Ltd., Babcock & Wilcox Vølund A/S, Constructions Industrielles De La Editerranée (CNIM), Covanta Energy Corporation, Essent N.V., Haase Energietechnik AG, Wood Group, Qinetiq, and Pacific Renewable Fuels Inc.
Waste to Energy Market Key Developments:
- In 2016, a pre-feasibility study was carried out for developing waste to energy project of Emirates Waste To Energy Company (a partnership between Masdar and Bee’ah) in UAE. This is expected to be the first waste to energy facility in the UAE. The facility is expected to get operational by the end of 2020 wherein it is expected to process about 37.5 tons of municipal solid waste per hour.
- In February 2019, the East Delhi Municipal Corporation (EDMC) commissioner of India, signed a memorandum of understanding (MoU) with the National Thermal Power Corporation (NTPC) to develop an ‘integrated waste processing facility’ in Delhi, India. This facility is expected to be completed by 2021 and expected to have a capacity to process 2,000 metric tons of waste and produce 12 MW electricity.
- In October 2018, ACCIONA S.A. announced to develop first large-scale thermal waste to energy plant in Australia which will be located at Kwinana Industrial Area. This plant is expected to process up to 400,000 tons of waste per year and is estimated to export about 36MW of electricity to the grid.
- Moreover, in August 2019, ACCIONA S.A. won US$ 435.25 Mn contract of waste to energy ‘Ness Energy Project’ in Aberdeen, Scotland. Through this contract ACCIONA will construct and operate this waste to energy facility which is expected to process about 150,000 tons of municipal solid waste per year to generate electricity.
