hazardous and biomedical waste

The role of municipal governments is important in the proper local management of solid waste. Under the Nunavut Land Claims

Agreement, municipalities are entitled to control their own municipal disposal sites. Local environmental and safety

standards are determined, in part, by how the land is designated under municipal government development plans (i.e. land use

zoning).  Solid waste may be deposited into municipal landfill sites only with the consent of the local government. The local

fire department may also be called upon if a fire or other public safety issue is identified.

Solid waste incinerators are engineered systems that are capable of routinely achieving burn temperatures in excess of 1000oC

and a holding time of at least one second. Properly designed and operated incinerators are able to effectively and safely

destroy a wide range of waste.  Only incinerators designed for burning mixed municipal solid waste are discussed in the

guideline. The incineration of

hazardous and biomedical waste and sewage sludge requires specific equipment, operational controls and training that are

beyond the scope of the current document.

There are four basic types of incinerators. They vary based upon the number of burn chambers they have, the amount of air

provided to each chamber and how waste is fed into the primary burn chamber.

hazardous waste, biomedical waste

Dual-Chamber Starved    The primary burn chamber receives less air than is needed to achieve full
Air System    combustion. Gases from this incomplete combustion then pass into a second burn chamber where sufficient air

is injected and complete combustion is achieved.

Single Chamber Excess    More than a sufficient amount of air (as much as 50% more than the amount
Air System    of air needed) is injected into the single burn chamber to achieve complete combustion of the waste.

Continuous Feed    An incineration process that is in a continuous burn cycle.  A continuous feed
Incinerator    incinerator operates without interruption throughout the operating hours of the facility by having waste

continually added to the primary burn chamber.

Batch Feed Incinerator    An incineration process that is not in a continuous or mass burning cycle.  A batch feed incinerator

is charged with a discrete quantity or single load of waste at the beginning of the burn cycle.

Batch feed dual-chamber controlled air incinerators currently operate at several remote industrial locations in northern

Canada and Alaska.  Although they are generally considered to have the highest qualities of all the incinerators and open

burning methods mentioned, they must be designed for the type and quantity of waste to be burned. Too little heat and holding

time will not allow waste to burn properly; too much heat will damage the incinerator.

Figure 5 illustrates the design of a typical batch feed dual-chamber controlled air incinerator. The main features of this

type of incinerator are:

Batch operation allows greater control of temperature and air throughout the burn process. Air turbulence can be reduced in

the primary chamber so fewer particulates are released into the air from the stack.
Although a wide range of wastes can be destroyed, waste may have to be segregated and remixed in order to achieve a

uniform heating value close to the design point of the incinerator.
Externally supplied fuel and electricity are needed for the burners and forced air ventilation. A properly operating dual-

chamber controlled air system will reduce problems with animal attraction as the production of bottom and fly ash and smoke

is minimized.

Section 2.3.2 is intended to provide the reader with a brief introduction to incinerators. It is not intended to provide

information suitable for the design, selection or operation of an incineration system. Any person considering the purchase of

an incineration system should first consult the system’s manufacturer or other qualified persons with expertise in the

incineration of solid waste.

Allentown, PA Kills Controversial Waste Incinerator Proposal

More than two years after the deal’s controversial approval, Allentown has terminated its contract with Delta Thermo Energy, ending speculation about whether the company would ever build a proposed waste-to-energy facility in the city.

In a letter dated Sept. 26, Allentown solicitor Jerry Snyder wrote that Bucks County-based Delta Thermo Energy had “consistently failed to advance” plans for a 48,000-square-foot facility on Kline’s Island that would have burned pulverized municipal waste and sewage sludge to generate electricity.

While Delta Thermo received approval for two permits from the state Department of Environmental Protection in May 2014, the company repeatedly failed to meet extended deadlines to acquire financing for the $49 million project, the letter states. It became clear that Delta Thermo could not meet a deadline of Jan. 1, 2016, to complete construction of the plant, according to the letter.

“Under the circumstances, the city has no reasonable alternative than to declare the agreement terminated,” Snyder wrote.

Asked Tuesday if he had a response to the letter, Robert Van Naarden, president of Delta Thermo, said he would have a formal statement in the next several days. He then said he did not know what a reporter was asking about.

“I don’t need to speak to you,” Van Naarden said.

Mayor Ed Pawlowski said he was disappointed that the contract had to be terminated, but it was a financing issue, not a problem with the company’s technology that killed the deal.

“At this point in time, we need to move on,” he said.

From the time it was first discussed in 2010, the proposed plant was a highly contentious issue for members of Allentown City Council and the public. The project was panned by local environmentalists, and the components used in the proposed waste-to-energy process have never been used in combination in the United States.

Developers initially failed to convince council members of the merits of the project. The plan failed after a 3-3 vote in February 2012. One month later, developers managed to sway Councilwoman Cynthia Mota, who cast the deciding vote in favor of the proposal during a raucous March 2012 council meeting attended by more than 400 people.

Since then, Delta Thermo has had difficulty finding private financing for the experimental plan, fueling rumors that it would never be built. The city’s agreement with the company paid for up to $500,000 in consulting fees to explore the project — to be reimbursed if the plant was built — but put the burden of acquiring financing on the company.

In December 2012, Van Naarden told The Morning Call that there was “zero concern” about not finding a financial backer. The city’s letter states otherwise.

Delta Thermo “consistently failed to satisfy the financing requirement” in the agreement, Snyder states in the letter. An initial financing deadline of Jan. 31, 2013, was not met, and multiple extensions were granted, including the most recent extension that expired April 1 of this year.

Shortly before that date, Delta Thermo requested an additional extension for financing, the letter states, but city officials asked for additional assurances that the project could be completed by Jan. 1, 2016. Letters were exchanged throughout the summer between the city and Delta Thermo. In August, city officials denied a request from Delta Thermo for access to the Kline’s Island site to begin preliminary work.

In September, Delta Thermo officials told the city that they were no longer working with their previous financial backer, and planned to have the financing underwritten by Stern Bros. A letter from Stern Bros. to the city stated its “confidence” in financing the project if the deadline were extended to June 1, 2016, according to Snyder’s letter.

Allentown’s garbage contract will be rebid in 2015, Pawlowski said. There was no way the plant was going to be operational in time for that process.

“We provided every opportunity for them to make the deal; there were a number of extensions,” Pawlowski said. “We got to a point where we couldn’t move any further. I have to have some sort of a commitment in place before I bid out this contract in 2015.”

Pawlowski said he is committed to the idea of finding an alternative place for Allentown’s trash. It may still be possible to find another company that could build a waste-to-energy facility in the city, he said.

“I see this as one of the most critical issues for us, and we’re going to work for it,” Pawlowski said. “We’ve set the groundwork and a platform for us to continue to look for technologies for solve our garbage problem.”

The termination of the contract means Allentown will have to eat the nearly $500,000 it spent on consultants to vet the financial and technological aspects of the waste-to-energy plan. Two consultants provided conflicting reports to city officials about the technology needed, one saying he was confident the plan would work, the other stating there were “a number of technological, performance, operating and environmental risks.”

Pawlowski said he didn’t view the money as wasted. The city now has a “template” that can work for a potential contract moving forward, he said.

“I would have been criticized highly if I didn’t bring in the best professionals,” Pawlowski said.

Council Vice President Ray O’Connell, who cast one of the two no votes on the proposal in 2012, said it became clear in recent months that the company was never going to be able to build the facility on time. The city should try to recoup consulting fees, he said.

“My bottom line, No. 1, is that I’m extremely happy that it’s not going to be built,” he said. “No. 2, let’s go after the $500,000 that was spent.”

In addition to public outcry, Delta Thermo’s controversial proposal prompted a failed ballot question in 2013. The question, which would have asked voters if they wanted real-time monitoring of new air-polluting facilities and live disclosure of emissions data, was thrown out by the Lehigh County Board of Elections for lacking DEP approval. The decision was upheld by Lehigh County Court, and an appeal was later dismissed by Commonwealth Court.

Dan Poresky, one of the activists who opposed the plan and helped organize the ballot question, said a group of activists was working on raising $25,000 to pay two attorneys to take further legal action challenging a previous court ruling and the DEP for issuing permits to Delta Thermo. Despite rumors that financing was not in place, organizers did not want to take a chance that the plant would be built, he said.

“The city has been saved both environmentally and financially from a major mistake,” Poresky said when asked about the termination. “This is not the way to handle trash and sewage sludge.”

Councilwoman Jeanette Eichenwald, who voted against the proposal, said Delta Thermo’s proposed technology was unproven and environmentally unsafe. It was not surprising that investors could not be found, she said.

City officials should treat the experience as a lesson, Eichenwald said, and take a closer look at how the city spends money on consultants.

“I’m gratified that this phase of Allentown city life has come to an end,” she said. “I feel vindicated.”
