Accordant Energy starts building municipal solid waste treatment plant in South Carolina
09 March 2018US: RePower South, a licensee of Accordant Energy, has started building a municipal solid waste (MSW) processing plant at Moncks Corner in South Carolina. The unit will use Accordant's ReEngineered Feedstock technology to process 50t/hr of MSW to make the company’s ReEngineered Feedstock product, a type of refuse-derived fuel (RDF). ReEngineered Feedstock will be marketed to cement plants and other industrial users.
"The RPS team has decades of experience in the recycling, solid waste, energy, finance, and construction industries, having built, owned, and operated multiple recycling and solid waste companies. We are confident this first commercial facility utilising the Accordant technology will improve recycling performance and landfill diversion while providing a renewable solid fuel for cement kilns and utility and industrial boilers," said Paula A Calabrese, Senior Vice-President and Chief Strategy Officer of Accordant.
Accordant says that its ReEngineered Feedstock product can be engineered for a variety of combustion applications and is physically and chemically designed to mimic the properties of coal. The product also holds a non-waste fuel determination from the Environment Protection Agency (EPA) allowing regulatory benefits for its users.

RePower South uses Bulk Handling Systems to build waste processing plant in South Carolina
31 January 2018US: RePower South (RPS) has started building the Berkeley County Recycling and Recovery Facility, a mixed waste processing plant. The turnkey recovery system will be provided by Bulk Handling Systems (BHS) under an engineering procurement and construction (EPC) agreement with Barnhill Contracting Company. When production begins in early 2019, the Moncks Corner, South Carolina plant will process 50t/hr of mixed waste sourced from Berkeley County to recover recycled commodities and a fuel feedstock.
The plant will use a BHS FiberPure system, consisting of BHS screens, NRT optical sorters and Max-AI autonomous quality control units to remove unwanted fractions to produce an end product with minimal manual sorting. Non-recyclable fibres and plastics destined for fuel will undergo further filtering by NRT SpydIR optical sorters equipped with MetalDirector options to remove unwanted contaminants. Max-AI AQCs are also utilised in each sorting position on the container line. In total, the system will use seven NRT optical sorters and nine Max-AI AQCs. In addition, Loesche Energy Systems will provide a Loesche RocketMill for size reduction. The system will also features two Kadant PAAL balers.
N+P Recycling views Chinese plastics ban as an opportunity
23 January 2018Netherlands/UK: N+P Recycling says that it views a Chinese import ban on plastics as an opportunity for its business. As the Dutch company offers a variety of waste derived fuels for various applications it is encouraging companies to split both fractions to get the optimal waste solutions for each individual quality. Lower calorific value (CV) products are better suited to waste incineration plants whilst higher CV products are typically used by cement, lime, steel and power plants.
Lower grade materials, typically within an 8 - 12GJ/t range, are supplied within many of N+P’s long-term supply contracts, to users within the UK and within Europe. There are also a number of possibilities for materials that are in-between the standard refuse-derived fuel (RDF) and solid-recovered fuel (SRF) qualities, or mid-CV range (12 - 16 GJ/t). For higher quality materials, N+P has a number of solutions all focused on the replacement of primary fossil fuels such as coal.
N+P Recycling produces a higher CV waste fuel product called Subcoal. It is currently building a Subcoal plant at Teesside in the UK with a production capacity of up to 0.22Mt/yr. It has started to source and contract non-recyclable waste streams such as materials recovery rejects, industrial residues and plastic residues for unit. It is expected to open in the third quarter of 2018.
Austria: Rohrdorfer Group has awarded an engineering, procurement and construction (EPC) contract to Humboldt Wedag, a subsidiary of KHD, for the modernisation of the kiln line at its cement plant operations in Gmunden. The upgrade will enable the flexible usage of a wide range of waste fractionally pre-treated derived fuels on a high substitution rate.
The modernisation project comprises the design and supply of KHD’s world´s first ever Pyrorotor Cacliner Technology, as well as the replacement of the existing satellite cooler with a new generation Pyrofloor PFC2 clinker cooler. The existing three station rotary kiln will be fitted with a new kiln drive and a new kiln hood as well as kiln inlet and outlet.
With the installation of the new Pyrorotor Cacliner Technology from KHD the Gmunden plant will be able to burn very coarse waste derived fuels including whole rubber tires, which will lead to drastically reduced requirements in regard to waste pre-treatment. Therefore, the kiln modification will also emphasise on pollutant emission reduction.
The contract includes: three new preheater cyclones; a new preheater ID-fan; a tertiary air duct; a Pyrotop compact calciner mixing chamber; Pyrorotor Calciner burning chamber technology, a Pyroclon Calciner Burning System; a new kiln bypass unit; a multi-fuel Pyro-Jet kiln burner for primary and secondary fuels; a new kiln drive and kiln hood; a Pyrofloor PFC2 clinker cooler equipped with a Pyrocrusher roller type clinker crusher; and Simulex plant simulation software.
KHD services include the dismantling of existing equipment parts as well as the engineering, design, supply and erection of new equipment including commissioning services. Commissioning of the new system is scheduled for April 2019.
PPC to boost alternative fuels plans in South Africa
19 December 2017South Africa: PPC plans to expand its alternative fuel programme as part of a cost saving drive. The producer plans to start using refuse derived fuel (RDF) at its De Hoek cement plant in the Western Cape, according to the Pretoria News newspaper. This will follow the current use of tyres as a fuel at the unit. RDF will be sourced from Cape Town, Drakenstein and Swartland. Savings are expected to be realised from the change in fuel mix by mid-2019.
PPC added that it didn’t expect any disruption to its supply of waste tyres at De Hoek caused from the shutdown of the government’s Recycling and Economic Development Initiative of South Africa (REDISA). Chief executive officer (CEO) Johan Claassen said that the company had anticipated the closure and built up supplies of tyres at the plant and at a site at Vissershok.
US: Essroc Cement’s appeal against the Clark County planning commission decision to stop it burning alternative fuels at its Speed Cement plant in Indian has been blocked. The Clark County Circuit Court ruled the plant did not follow the proper administrative procedures before filing its lawsuit seeking to overturn a local zoning decision, according to the Courier Journal newspaper. Burning waste fuels at the site has been in dispute since the company first proposed the action in 2014.

Canada: The Nova Scotia provincial government has given permission for Lafarge Canada’s Brookfield plant to burn tyres for one year. Environment Minister Iain Rankin said that the results would be examined at the end of the pilot period.
“My decision is based on the science and evidence associated with this application as well as the public feedback received which helped to shape conditions of the approval,” said Rankin. “This pilot will confirm if the company can reduce current carbon emission levels at its Brookfield plant as the information provided in the application indicates.”
Terms of the pilot project include limiting tyre-derived fuel to 15% of total daily input and no more than 20t/day, forming a community liaison committee to keep residents informed of the project’s status and address their questions and to develop a complaints resolution plan.
Lafarge Canada will also be required to submit plans for related activities and apply for a temporary industrial approval to operate the pilot project. The required plans include: tyre storage and waste management; air dispersion modelling; continuous monitoring of emissions; stack testing before and after the pilot begins; and an emergency response if there is a malfunction of the kiln. The results of the pilot will be made public through a community liaison committee.
However, the plan has received criticism from the local community on environmental grounds. The local press has also questioned whether the provincial government is subsidising Lafarge Canada’s fuel costs as the region charges consumers recycling tariffs on goods such as tyres. A previous plan by the cement producer to burn tyres in the region in 2007 was blocked by the local government.
