Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of AD plants to maximise efficiency and prevent the risk of failure.

Introduction
In 2009, renewable energy accounted for just 3% of the UK’s energy supply. However, the UK Government has a target to raise this contribution to 15% by 2020 as part of its strategy to fight climate change. Along with wind, solar and various other sources of renewable energy, AD has an important role to perform in helping to achieve the renewable energy target whilst also helping with the management of organic waste.

Pipe Center and Climate Center are expanding their central technical team to support expansion into new market sectors and the introduction of renewable technologies.

The enlarged technical team will provide a single point of contact for customers on major projects and tap the in-depth product experience available across Pipe Center and Climate Center and - where relevant - the wider Wolseley UK.

Staff at Redbridge Council have a brighter future thanks to the installation of a voltage optimisation system that has not only reduced its running costs and carbon footprint but also cut the number of office lights fusing on a regular basis.

The Voltis voltage optimiser from Marshall-Tufflex Energy Management has been installed in four locations across the council as part of a programme of energy efficiency measures implemented by the authority. Post installation the voltage of each location dropped by up to 25Volts.

The Etesia UK 'Green Technology' roadshow has reached its first pit-stop, bringing the turf maintenance machinery manufacturer's spring tour of the country to a successful conclusion.

The recent roadshows held at Merrist Wood College, Guildford and Edge Hill University, Lancashire in late March sandwiched an invitation to speak about environmentally-friendly grounds maintenance equipment at the Plant Network Conference held at the University of York.
