London ‘pulling ahead’ as Goodwin unveils recycling plan

London is “starting to pull ahead” in terms of waste treatment infrastructure and its potential to provide district heating, but there is still considerable work to be done to address recycling collections in the city.

This was the message during the first session of the London Conference near Regent’s Park last week (16 March), which was organised by letsrecycle.com.

Liz Goodwin, the recently-appointed chair of LWARB, and Andrew Richmond, policy and programme manager at the Greater London Authority, took to the podium to outline their ambitions for recycling in the city.

Commenting on the status of waste infrastructure, Mr Richmond argued that “London is starting to pull ahead” referring to district heating available through Veolia’s SELCHP energy from waste plant in Southwark, and Viridor’s upcoming Beddington EfW plant to the south of the city.

He said that “early modelling suggest that things are not too bad for infrastructure in London”, before going on to ask the audience “Is it the right type of infrastructure?”

UK launches new 'district heating task force'

A new district heating task force has been launched to solve challenges faced by the sector.

The Association for Decentralised Energy’s (ADE) initiative will provide recommendations on how the industry and UK Government can work together to deliver a competitive, subsidy free heat network market with strong protections for consumers.

By accessing waste heat and connecting it directly to the end customer, heat networks can provide low carbon heat, control energy costs and increase security of supply.

However, the ADE says heat networks need to see increased certainty and lower investment risk if the sector is to attract the capital it needs to stand on its own and become a key part of the transition to a green economy.

It hopes to address the competition and pricing challenges created by the natural monopoly of district heating networks and explore opportunities to help expand district heating at the local government and national government levels.

Minister for Industry and Energy, Jesse Norman said: “Heat networks are already helping to decarbonise our heat supply and provide affordable low carbon energy to thousands of homes and businesses across Britain’s towns and cities.

“The task force will play an important role in considering how to establish a sustainable and fair market as the sector expands. We look forward to receiving the recommendations.”

Veolia: Waste-Powered Heating is Now a Reality in the European Metropolis of Lille

The European Metropolis of Lille has awarded Covalys, a joint venture co-owned by Veolia (Paris:VIE) (65% via its subsidiary Valnor) and Idex (35%), the public service delegation contract to operate Antares, the metropolis’ energy recovery facility in the town of Halluin.

The 12-year contract represents cumulated revenue of €295 million. It is a major step towards energy transition for the metropolis since the energy generated by the thermal treatment of household waste will supply two urban heating networks in Roubaix and Lille.

Turning household waste into heating for collective housing

Antares treats up to 350,000 tons a year of household and assimilated waste collected in the metropolitan area. This waste is incinerated at very high temperatures (850 °C) in three oven lines, ensuring complete combustion and generating over 650 GWh of energy annually, enough to heat over 70,000 homes for a year.

Previously, the energy was only used to cover the plant’s own needs and to produce electricity. Now, 40% of the energy produced will directly supply the R-énergie and Résonor urban heating networks of Roubaix and Lille respectively. The energy potential of its household waste represents a source of renewable and recovered energy for the European Metropolis of Lille. In line with the French Energy Transition Law, a virtuous loop will be created locally with the waste generated by the urban community used to heat its collective housing. Users will enjoy green energy at competitive prices, notably because of the tax credits awarded for using renewable sources to supply over 50% of the heating networks’ energy requirements.

“The success of the service we provide for the European Metropolis of Lille demonstrates our capacity to offer municipalities new, efficient solutions that help them develop a local circular economy,” commented Bernard Harambillet, CEO Waste Solutions for Veolia in France. “The combined expertise of Veolia and Idex, which already manages 50 heating networks in France, was key in providing the European Metropolis of Lille with the necessary assurances,” added Thierry Mourot, Managing Director of the North region of France at Idex.

Creating an energy highway

The high-capacity insulated network designed to link Antares up to the heating networks will be one of the longest energy transmission networks ever commissioned in France. Its 19 km-long route was carefully planned to minimize the impact on residents during the works phase and follows either roads or greenways. When it is fully operational, probably by the end of 2020, it will represent a long-term energy supply for both urban heating networks and enable their development.

District heating market trends for 2017

Research firm, Transparency Market Research, have released a report which highlights their predictions for the district heating and cooling market over the course of 2017.

The global district heating and cooling (DHC) market features a low concentration of component suppliers with no big players. Most companies operate at local or regional levels where proximity to consumers helps avoid extra operational costs and efficiency losses, states Transparency Market Research in a new report. The market dynamics are highly susceptible to changes in terms of technology and scale of projects. “As DHC systems mostly belong to state-owned entities, government support and funding play a key role in operational efficiency of a DHC project,” states a TMR analyst.

TMR estimates that the global market for direct heating and cooling systems will exhibit a 5.8% CAGR and a 6.2% CAGR over the period between 2016 and 2024, in terms of energy sales volumes and revenue, respectively. At this pace, the market is expected to rise to a revenue-wise valuation of US$243,428.3 mn by 2024. In terms of energy sales volume, the market is expected to reach 12,187,491.8 tera joules by 2024.

DESMI Pumps More Than a Match for Power Plant Residues

Removing toxic residues from power plant flue gases is as tough on equipment as it sounds. Known for having the toughest pumps in the business, DESMI is looking to take on more of the power plant challenge.

Powering forward

The world is gradually moving away from traditional energy production such as coal and gas and, as a result of the drive towards sustainability in recent years, waste-to-energy and biomass power plants have become a popular production method. Like their fossil-fuel colleagues, however, these plants must remove or ‘scrub’ potentially hazardous pollutants from the flue stage of the process.

The system requirements for flue gas cleaning depend on a long list of factors. Gas cleaning of complex flue gases can be realized in many ways, either in a few or several steps. Each plant is more or less unique, and must be evaluated separately to achieve an optimal solution.

Gas-cleaning systems can typically be categorised as solutions to remove:


  • Particles or dust collection without the need for pumps.
  • The water-soluble gases SO2, HCl, HF and NH3, performed using either wet or dry gas cleaning.
  • NOx (mainly NO)
  • Highly toxic substances such as dioxin and mercury (Hg)


In all cases, where there are highly-corrosive chemicals flowing through pumps 24 hours a day, a production facility is likely to face costly repercussions in terms of risk, productivity and repair if the machinery should fail.

Hard-earned reputation

Quality of all components is obviously a key factor for both utility and manufacturer, especially when dealing with the processing and neutralisation of dangerously toxic chemicals. The pump units need to be particularly resilient to corrosion, they must be able to withstand continued load and usage over long periods, and they must ensure minimum down-time. The ramifications of taking a plant offline for essential pump maintenance due to malfunction or wear and tear can be immense – and commercially unacceptable. For these reasons, ultra-high quality pumps are an absolute must in such application areas, and DESMI’s centrifugal pumps in super-duplex stainless steel are well-suited to the task.

DESMI believes that the versatility, strength and support services of its product line makes it an ideal choice for turnkey and sub-system companies delivering to both large- and small-scale plant projects. As with all DESMI pumps at this level, service including replacement of bearings and mechanical shaft seal can be carried out without removing motor and piping, saving both time and money for the power plant, enabling utility staff to carry out service tasks themselves, and boosting uptime statistics.

Christian is confident of DESMI’s ability to maintain customer satisfaction with its solutions: “Often, utilities require an extended warranty period, corrosion guarantees and fast customer service that can match such an aggressive, high-stakes environment. And that’s something we can definitely provide.”

With more than 100 years of heavy-duty pump development and manufacturing for a broad range of demanding applications, DESMI is likely to have a lasting impact on power generation infrastructure for decades to come.

Christian Busch, Danish-based industrial pump manufacturer DESMI’s sales manager for the utility sector across Europe, the Middle East and Africa, is very aware of the impact on machinery: “The ‘scrubbers’ are located after the boilers. Continued exposure to this combination of factors can rapidly have a detrimental effect on the pump machinery if it’s not specified and manufactured appropriately. We’ve spent more than two decades working with a very similar set of factors in pump supply to the maritime sector, and it’s partly from this that we got the inspiration to apply our technologies to land-based flue gas scrubbing, too.”

Coming ashore

DESMI’s expertise in supplying corrosion-resistant pumps to the shipping industry has received extra focus in recent times. Particularly following the introduction of more stringent regulations governing sulphur emissions. Now, the company is increasingly the subject of attention in the utilities sector, too, for the supply of efficient, reliable and durable pumps in the various stages of the wet scrubbing process.

“We have built our reputation on several aspects that are equally as important in the power generation industry as they are in the maritime world,” says Christian Busch. “It’s the same formula, you might say, designing pumps fit for purpose and beyond, with reliability, efficiency, durability, ease of fitting and maintenance, and cost effectiveness as the key success factors.”

Over the past five years, DESMI has installed high-durability systems in power plants in its home market, and is now looking to extend its utility sales beyond the Nordic region with Christian Busch at the helm. And there is clearly a need in the marketplace: “We’re focused on getting to know the big companies that specialise in making custom-built systems for the various power plants – and we’re discovering that they are just as keen to learn more about us.”
