Solid waste generation has been projected to increase worldwide. Presently, the most applied methodology to dispose of solid waste is landfilling. However, these landfill sites, over time release a significant quantity of leachate, which can pose serious environmental issues, including contamination of water resources. There exist many physicochemical and biological landfill leachate treatment schemes with varying degrees of success. With an increasing focus on sustainability, there has been a demand for developing eco-friendly, green treatment schemes for landfill leachates with viable resource recovery and minimum environmental footprints. Microalgae-based techniques can be a potential candidate for such a treatment scenario. In this article, research on microalgae-based landfill leachate treatments reported in the last 15 years have been summarized and critically reviewed. The scale-up aspect of microalgae technology has been discussed, and the related critical factors have been elucidated. The article also analyzes the resource recovery potential for microalgal techniques with respect to leachate treatment and explores possible methodologies to minimize the environmental footprints of the microalgae-based treatment process. The future research potential in the area has been identified and discussed.

Solid Waste Management System

Created in 1978, the Solid Waste Authority of Palm Beach County (Authority) has developed an “award winning” solid waste management system that includes franchised solid waste collections and the following facilities to service the residents and businesses in Palm Beach County, Florida: • North County Resource Recovery Facility (NCRRF); • Residential and Commercial Recovered Materials Processing Facility; • Five Transfer Stations; • Class I Landfill; • Class III Landfill; • Biosolids Pelletization Facility; • Ferrous Processing Facility; • Woody Waste Recycling Facility; • Composting Facility; and • Household Hazardous Waste Facility. The Authority has proactively planned and implemented its current integrated solid waste management program to ensure disposal capacity through 2021. However, like many communities, the Authority anticipates continued population growth and associated new development patterns that will significantly increase demands on its solid waste system, requiring it to reevaluate and update its planning to accommodate future growth. The NCRRF, the Authority’s refuse derived fuel waste-to-energy facility, has performed very well since its start up in 1989 processing over 13 million tons of MSW, saving valuable landfill space and efficiently producing clean, renewable energy. As the NCRRF approached the end of its first 20 year operating term, it became necessary to complete a comprehensive refurbishment to ensure its continued reliable service for a second 20 year term and beyond providing for continued disposal capacity and energy production for the Authority’s customers. The Authority renegotiated and extended its operating agreement with the Palm Beach Resource Recovery Corporation (PBRRC), a Babcock & Wilcox Company, for an additional 20-year term. The Authority selected BE&K Construction Company (BE&K) and entered into an Engineering, Procurement, and Construction contract (EPC Contract) to perform the refurbishment. The Authority, with assistance from its Consulting Engineer, Malcolm Pirnie, Inc., developed the minimum technical requirements and negotiated the EPC Contract with BE&K. The design and procurement efforts were completed in early 2009 and on-site construction refurbishment activities commenced in November 2009. The refurbishment has a total estimated cost of $205 million. The refurbishment work is sequenced with the intent that one boiler train will remain operational to reduce the impact to the Authority’s landfill and maximize electrical production and revenues during the refurbishment period. This presentation will focus on the improvements to operations as a result of the refurbishment and its positive effects on the Authority’s integrated solid waste management system.

Municipal solid waste from Lee County and Hendry County is processed at the Lee County Solid Waste Resource Recovery Facility (the “Facility”). Lee County (the “County”) owns the Facility, which began commercial operation in December 1994. The Facility’s current permitted capacity is 1,320 tons per day (tpd), provided by two 660-tpd boiler units, at a reference waste of 5,000 Btu. Covanta Energy of Lee, Inc. operates and maintains the Facility under the terms of a Service Agreement with the County that runs through 2014. Covanta also designed and constructed the Facility. The expansion of this Facility will be the first new construction of a municipal waste combustion (MWC) unit since the New Source Performance Standards were adopted. Despite the County’s comprehensive recycling program, the amount of solid waste the County delivers to the Facility has increased each year since the Facility began operation, primarily due to population growth. In 1999, this amount reached the Facility’s guaranteed annual capacity of 372,300 tons. In 2000, the Facility processed over 392,000 tons of municipal solid waste, while the County landfilled nearly 44,000 additional tons of processible waste. Current population projections for Lee and Hendry Counties suggest that processible solid waste generation will continue to increase, reaching nearly 550,000 tons by 2010. Rather than landfilling processible waste generated in excess of the Facility’s current capacity, it is the County’s intention to expand the Facility by adding a third 660-tpd boiler unit which would increase the Facility’s permitted capacity to 1,980-tpd. The original application for the Facility’s Power Plant Site Certification anticipated such an expansion, including provisions for a third 660-tpd MWC unit. Certain provisions for this third unit were incorporated into the Facility’s design and construction as well. These included providing the physical space for the third unit, the physical space for an additional flue for the third unit, and sizing the tipping floor, refuse pit, and certain common equipment for three units. The expansion will require a second turbine-generator unit and expanded switchyard, an extension to the existing turbine-generator building, as well as the addition of a third boiler unit and air pollution control equipment. The expansion will also require modifications to certain equipment and systems common to all boiler units in order to meet the additional capacity requirements of the expanded Facility. As of February 2003, the County is waiting for the Florida Department of Environmental Protection to issue a draft PSD Air Permit and is on scheduled to go before the Power Plant Siting Board in September 2003.
