Energy-from-waste plants
UK. Metso is supplying advanced automation solutions to two greenfield energy-from-waste plants located in the UK and built by Von Roll Inova Environmental Technology Ltd.
The first order is for the plant of Riverside Resource Recovery Ltd, a subsidiary of Cory Environmental, which will be the UK’s largest energy-from-waste facility when completed in 2011. Located in Belvedere, London, it will process around 585,000 tons of municipal and commercial waste per year, generating 72 MW of electrical energy. Most of the waste will be transported to the facility in sealed containers carried by barge on the Thames, saving at least 1.3 million HGV miles per year.
The second order will be supplied to Veolia Environmental Services’ 19.4 MW energy-from-waste plant located in Newhaven, East Sussex, and which will come on stream in 2011.
Metso’s delivery to both plants will consist of a metsoDNA distributed control system, an integrated boiler protection system and an information management system. Metso is said to have been chosen as the DCS supplier for RRR’s plant, because of its performance on two earlier projects at ASA Zistersdorf in Austria and at BIR Avallsenergi in Norway.

PET contamination eliminated
Germany. Highlighted on the S+S Separation and Sorting Technology GmbH stand at the Drinktec/PetPoint 2009 show in Munich is a new Flake Purifier for recycling plastic drink packaging.
Based on a modular concept, the machine can combine up to three sensors for contamination detection and, in addition to the third generation of refined sensors for metal and colour separation, the machine is also equipped with a high-performance module to recognise contamination, including different types of plastic.
This means that PET flakes can now be separated from PVC flakes or organic material such as PLA (previously known to lower recycling material quality dramatically and even make high quality recycling impossible).
The intelligent combination with camera sensors enables the unit to further identify and separate dark blue and black particles, with inductive sensors detecting metal contamination. Until now, flake sorters have traditionally used only two sensors (metal and colour). The introduction of the multi-spectral sensor makes it possible to complete three sorting tasks simultaneously.
Depending on the application, PET recognition can be programmed as good material or
contamination. Features of the new unit include low power consumption, as no cooling unit is necessary, and availability with simple sensors, which can be replaced by multi-spectral sensors at any time should sorting requirements change.

Understanding waste
UK.
The recent story surrounding the export
of waste in containers from the UK to an overseas country highlights the problems associated with waste. Changes in legislation have made it essential to re-evaluate the waste aspect of any industrial activity to try and establish priorities.
The need to clearly define what the waste is, how it is handled and processed, plus the options available for using or disposing of it would appear to be funamental. However, waste by its very nature is variable and inherently difficult to categorise, making handling, processing and disposing of it a continuous learning experience.
An Institution of Mechanical Engineers
(IMechE) seminar on Sustainable waste management
, which takes place on 26 November 2009 in London, is intended to provide an insight into the subject, covering waste processing technologies currently employed to convert discarded material into useable resources.
The event is aimed at managers, decision-makers and local government, administrators who are responsible for planning, selecting and implementing waste handling facilities, as well as engineers and managers from equipment suppliers, technology suppliers, consultants, waste producers and processors involved in the design, supply, procurement or operation of waste handling and processing equipment.
Delegates will learn about the technologies available for reducing the amount of waste sent to landfill, opportunities for reusing waste as an energy resource and effective techniques for controlled handling and processing a variety of waste materials.
Other subjects under discussion include the energy park concept, pyrolysis systems, waste-to-energy plants, biomass as a fuel in the cement industry, storing biofuels, waste material properties and handling traits, and a review of current legislation.

Positive recycling figures
UK. The UK recycled almost two-thirds of all packaging produced in 2008, according to the latest figures from the Department for Environment, Food and Rural Affairs (Defra) and the Environment Agency.
Last year UK businesses contributed to the recovery of more than 7 mt of packaging waste of which 6.6 mt were recycled, an equivalent saving of roughly 8.9 mt of CO2.
Environment Agency Chief Executive Dr Paul Leinster said that 2008 was the best year yet for the amount of packaging waste recycled and that businesses would continue to be helped to meet their obligations, with tough action taken against those that avoid their responsibilities.
All EU member states have targets set by the EU on packaging recycling and recovery and the 2008 targets were recycling 55 per cent and 60 per cent recovery of packaging. There are also specific targets for a range of recyclable materials and the UK has met or exceeded its targets including: paper - 79.8 per cent recycled (target 60 per cent); glass - 61.3 per cent recycled (target 60 per cent); metal - 56.9 per cent recycled (target 50 per cent); plastic - 23.7 per cent recycled (target 22.5 per cent); and wood - 78.5 per cent recycled (target 15 per cent). |

Green light for waste-to-energy plant
UK. An integrated mechanical heat treatment facility with power plant at Bridgend, Wales, able to generate enough electricity to supply its own needs and that of approximately 4000 homes, has been given the green light.
3NRG is said to be the first company in the UK to acquire the necessary regulatory licences to operate the plant which employs a combination of steam treatment of solid waste, recovery of materials for recycling such as plastics, metals and glass, the remaining biomass, derived from paper, cardboard and food residues, put through a process known as pyrolysis to produce gas. This is used to create steam for a turbine that generates electricity, with surplus power fed to the national grid.
A pilot project has been running for some time at the former landfill site, initially licensed for waste processing but now given the go ahead for construction of the £25 m integrated plant due for completion in 2010.
Michael Flynn, chief executive and founder of FLI Environmental says: “We expect to build ten such plants in England, Scotland, Wales and Ireland over the next decade as we believe that this is the cleanest and most environmentally sustainable solution to processing residual solid municipal waste.” The system recycles or reuses 95 per cent of solid waste which would otherwise have been sent to landfill.
3NRG’s Business Development Director, Michael Geary expects the facility to provide a competitive waste processing service for local authorities and private waste contractors in the South Wales region, helping them to meet their targets for diverting waste from landfill.
