The 4th Australia-New Zealand Climate Change and Business Conference will be attended tomorrow morning by the Prime Ministers of Australia and New Zealand, Kevin Rudd and Helen Clark, who will give their views on climate change.


...More than 80 expert speakers from around the world will explore current climate change issues of relevance to business, such as implementing emissions trading and investments.


At the NZ Business Council for Sustainable Development's "clean billions" breakfast at SkyCity today, a report for the Tindall Foundation will be issued in support of Stephen Tindall chairing the climate change leadership forum, which advises ministers on emissions trading.


...But it softens the blow by adding that opportunities are available for businesses and the economy which actively embrace emissions trading and make efforts to cut emissions, improve products and reduce emissions costs.

...The gas would be used to fuel a Stirling engine, which would produce both hot water &ndash; to keep the biodigester plant at an optimum temperature - and electricity &ndash; to power an Icebank, which would produce enough ice to cool the milk to a safe storage temperature. 


&ldquo;It&rsquo;s an integrated energy system which addresses cleanliness, because it&rsquo;s using what is otherwise a waste product, and which cuts down on atmospheric and ground pollution,&rdquo; Mr Bywater says. 


...As well as reducing the amount of energy dairy farms draw from the national grid, it would also lessen peak loads on rural feeders and lessen the need for expensive re-conductoring of these lines.   &ldquo;At the moment, when a herd of cows comes in for milking, a much larger capacity is required as the refrigeration plant kicks in,&rdquo; Mr Bywater says.

Ian Bywater, a New Zealand based engineer, will be visiting the Isle of Wight on Wednesday 10 November as part of a whistle stop tour of the UK. 

...The council&rsquo;s Agenda 21 Co-ordinator, Jim Fawcett, came across the application, geared to the size of dairy farms on the Island and invited Mr Bywater to meet farmers individually if they are interested in looking at the system in more detail. 

...The spent sludge from the digester is a higher grade of fertiliser for grassland than raw manure while the biogas is used as fuel for a sterling type engine generator set, which produces both electricity and heated water. ...  He said: &ldquo;The technologies are individually well developed but not exploited; It is the combination of all three that makes the system viable, especially today where there are concerns about environmental pollution and use of non-renewable energy.&rdquo;

...An electrical power engineer, Mr Bywater&rsquo;s manure-to-electricity concept won a worldwide Engineering for a Sustainable Future competition organised by the UK Institute for Engineering and Technology in 2003. 


...Dairy is New Zealand&rsquo;s biggest export earner and the concept was a process extracting valuable energy from a waste product to smooth out electrical demand and make savings on dairy farms. 


...Mr Bywater said manure scraped from milking yards and increasing numbers of feed pads would be placed in 180,000-litre digesters heated to 35 degrees to liberate bio-gases made up of 65% methane and the rest carbon dioxide.
