The Greater Vancouver Sewerage and Drainage District is suing Maxxam Analytics International Corp. and Covanta Burnaby Renewable Energy ULC for allegedly failing to properly test fly ash samples from the district’s waste-to-energy facility in Burnaby.
The district filed a notice of civil claim in BC Supreme Court on October 16. Covanta, according to the claim, operates the incinerator plant under contract with the district, and the facility generates fly ash which has to be treated before leaving the plant and tested monthly to ensure compliance with hazardous waste regulations.
Non-hazardous fly ash is taken and disposed of at the Cache Creek landfill, the claim says. Samples analyzed by Maxxam in the summer and fall of 2012, however, came back indicating high levels of cadmium that exceeded acceptable levels allowed for disposal at the landfill.
The results, the district claims, “called into question the effectiveness of the treatment of fly ash” at the facility, forcing the plaintiff to incur costs by requiring more sampling and testing, investigating the cause of the high cadmium levels and finding an alternate disposal site for fly ash in Alberta. After the Ministry of Environment hit the district with an advisory letter of non-compliance, the plaintiff hired “consultants, experts and legal counsel” to help investigate.
An audit of Maxxam’s laboratory found that it didn’t follow proper methods, called the “Toxic Characteristic Leaching Procedure” and the “United States Environmental Protection Agency Method 1311” to test the fly ash, according to the lawsuit. The Ministry of Environment’s assessment found Maxxam’s results unreliable due to improper testing procedures and found that “Covanta’s quality control and quality assurance protocols at the WTEF [Waste-to-Energy Facility] were not sufficiently developed to identify if leachability was occurring or if a problem with the treated fly ash and/or the treatment system was occurring,” the claim states. In addition, the ministry found that Covanta couldn’t easily “provide assurance that the treated fly ash met the hazardous waste requirements under the Hazardous Waste Regulation.”
The district seeks damages for negligence, misrepresentation, negligent performance of a service and breach of contract. The allegations have not been proven in court and the defendants hadn’t filed responses to the claim by press time.
On Friday Attorney General Buddy Caldwell announced the State of Louisiana reached an agreement with Texas incinerator Veolia Environmental Services and Louisiana hazardous waste landfill Chemical Waste Management to ensure that incinerator ash associated with the recent Dallas Ebola virus occurrence will not be transported or disposed of in Louisiana, .
On Oct. 13 the Louisiana Attorney General’s office obtained a restraining order in the 19th Judicial District Court to temporarily stop the transport of incinerated Ebola ash into Louisiana.
The temporary retraining order was extended on Oct. 21 at the request of all parties, before ultimately arriving at today’s agreement.
Attorney General Caldwell said, “I am pleased today’s agreement ends this chapter in the controversy of the transportation and disposal of Ebola waste.”
Researchers at the University of York have concluded that PyroPure (UK) technology has the potential to transform the way in which hazardous waste is destroyed in clinical environments and say pharmacists, manufacturers and hospitals throughout the UK should consider trialling the system.
The announcement follows a six month Innovate UK-funded Knowledge Transfer Partnership project in which a team of leading scientists from the University’s Environment Department and Centre of Excellence in Mass Spectroscopy confirmed that the system helped to destroy active pharmaceutical ingredients (APIs) found within pharmaceutical waste on-site.
A total of 17 of the most thermally resistant APIs were selected for the trial, which revealed that PyroPure technology destroys over 99 per cent of APIs in 10 of the 17 tested and an average of 94 per cent of the ‘worst case’ pharmaceuticals.
Professor Alistair Boxall of the University’s Environment Department and former member of the DEFRA Hazardous Substances Advisory Committee headed the study. On the future of PyroPure as an alternative to high temperature incineration, he comments:
“There are big concerns over the negative impacts of pharmaceuticals on the natural environment. Inappropriate disposal of pharmaceuticals and emissions from manufacturing sites are thought to be important contributors to these impacts. Our work demonstrates that PyroPure could help reduce the levels of pharmaceuticals in rivers and streams and have big benefits for ecosystem health. The system also provides a range of other environmental and economic benefits that could radically change how waste of this nature is collected and destroyed going forwards. With PyroPure technology, hazardous waste and controlled substances no longer need to be transported across the country to incineration facilities, thus reducing the associated costs, carbon emissions and risks associated with moving waste from its point of origin to its point of disposal.”
Currently in the UK, pharmaceutical wastes are only disposed of in large-scale, high-temperature incinerators, which can be up to 200 miles away from where the waste is generated. The Environment Agency has previously indicated that PyroPure, which relies on pyrolysis, a thermochemical decomposition process using high temperatures and an absence of oxygen, followed by catalytic conversion to clean and convert the gases, could be the first viable alternative to high-temperature incineration for pharmaceutical wastes.
On the trial’s success, Peter Selkirk, PyroPure Ltd’s Executive Chairman, adds: “This is a huge step forward for PyroPure technology and the healthcare sector. For too long now, we have been overly dependent on incineration as the only viable route in which to dispose of hazardous waste. Not only is it expensive but it’s also open to security breaches, particularly when the waste needs to be transported long distances. Now that PyroPure is a proven technology I’m confident that this breakthrough will pave the way for a new approach to waste disposal and irrevocably change the model for waste collection within clinical environments across the world.”
The trial, which formed a Knowledge Transfer Partnership between PyroPure Ltd and the University, also revealed how on-site energy recovery during the PyroPure process is at least 75 per cent compared with 20 per cent for a high-temperature incinerator.
Each PyroPure unit is the size of a chest freezer. The user simply opens the unit’s lid and places the waste within the chamber before initiating the process of pyrolysis to destroy it.
Power in Denmark is increasingly being generated in plants burning waste imported from England. The practice is being called an economical and environmental boon on both sides of the equation.
The AVØ incinerator in Frederikshavn produces heating and power for the area by burning trash from England.
“It is mainly construction waste like pieces of wood, cardboard and plastic from Manchester,” AVØ operations manager Orla Frederiksen told DR Nyheder. “I guess we have 600 tonnes here that provide a good combustible mixture we can then turn into district heating and power.”
Good for the bottom line
The incinerator in Frederikshavn has doubled its imports of the English waste in the past year.
Incinerators in Aalborg and Hjørring are also burning British trash.
“The heating we produce using the waste is cheaper than what we can generate with natural gas,” said AVØ head Tore Vedelsdal. “And the British are interested because they lack incinerators and pay heavy taxes on landfills.”
Good for the environment
Vedelsdal said that the environmental angle works for both countries.
“They save on having to bury the waste and we save on the consumption of natural gas,” he said.

Environmental protection agency Miljøstyrelsen said that last year up to 200,000 tonnes of non-hazardous waste from England was incinerated in Denmark – nearly six percent of the total volume of combustible material used.
