Negative emissions of carbon dioxide will likely be needed to meet the <2°C warming above the pre-industrial level goal of the Paris Agreement. A major technology option is combining Biomass Energy with Carbon Capture and Storage (BECCS) in the industry and power sectors. Biogenic waste contributes a major share for the numerous waste-to-energy plants around the world. This implies that adding a CCS facility to a waste-to-energy plant could establish a value chain for negative carbon dioxide emissions. Hence a waste-to-energy plant could deliver four services to society: waste management and avoided pollution, service district heating system, remove carbon dioxide from fossil-based waste categories, and generate negative carbon dioxide emissions from biogenic waste. A major barrier to deploying Bio-CCS at a waste-to-energy plant is a high investment and operation cost for the carbon dioxide capture plant, combined with lacking reward for the negative carbon dioxide emissions. In this paper I explore promising business models that could incentivize owners of waste-to-energy plants to install CCS facilities, assuming that government has established an infrastructure for transportation and permanent storage of carbon dioxide, as well as the basic framework for accounting for negative emissions. The business models are either founded on waste renovation customers being able and willing to pay for the additional cost of producing negative emissions of carbon dioxide directly or through certificates, or investments in CCS being incentivized by government through a guaranteed price or tax rebates for negative emissions of carbon dioxide.

This study presents an overview of distinctive features of America’s first new waste-to-energy plant, which is a source of renewable energy and reduces greenhouse gas emission. With combustion and air pollution equipment designed and supplied by The Babcock & Wilcox Co. (B&W), the new facility addresses the pollution and cost issues that stopped municipalities from building waste-to-energy plants. It eliminates the burial of problematic wastes that routinely emit tons of volatile organic compounds and problematic chemicals. Waste-to-energy plants produce lower net greenhouse gas emissions than any landfill option. Not only do they displace fossil fuels to produce electricity, but also they effectively eliminate methane landfill emissions by burning the biodegradable landfill waste that forms methane. Test results show that the facility’s emissions are, at their maximum, an order of magnitude lower than those limits. This makes it the best in class of any waste-to-energy plant in the world. Waste-to-energy plants give municipalities facing rising landfill costs an economically and environmentally sound alternative to consider.

This work provides a computational model of the chemo-mechanical behavior of based refractories used in waste to energy plant (WTE) linings. In this application, oxygen gas present in the atmosphere diffuses through the porosity and reacts with the refractory producing silica (SiO2). This new phase clogs gradually the pores and causes swelling of the refractory lining. The proposed thermo-chemo-mechanical model which simulates these phenomena is briefly summarized. The results obtained from the model implemented in a F.E code prove the ability of the model to reproduce qualitatively the swelling of post-mortem bricks taken from WTE linings.

Abstract This paper has been prepared to encourage communication between plant operators who have developed “in plant’ solutions to various problems encountered in waste-to-energy plants. Solutions presented include reciprocating grate designs, dry ash chute designs, ash water reuse clarification system, ash extractor level controls, easy access doors, and water clarification systems. Each problem is presented with solution(s) for each of the problems. A contact is provided for each solution for additional information.
