O2Compost SOQ Comprehensive

15 September 2015 To whom it may concern, Re: Letter of Recommendation for O2Compost Odour Mitigation at Envirofert’s Food Waste Composting Facility Auckland, New Zealand My name is Mike Lord and I am the CEO of Envirofert, a recycling and composting company based in Auckland, New Zealand (on the border of Waikato in the upper North Island). We are currently composting approximately 100,000 m3 of garden waste and 7,500 m3 of food waste per annum. Before I joined the company in 2013, Envirofert was composting garden waste using traditional windrows turned with an excavator. In 2012 the company started composting food waste as well. To better control the process they developed a negative pressure aeration system to provide oxygen and control the stronger odours that composting food waste produced. It became quickly apparent that the negative air system was too small for the volume of materials being composted, as it was not coping with the stronger odours produced during the composting process. Odour complaints began to occur on a regular basis from neighbours and we fell under the watchful eye of our regulators. Shortly after I started, I attended the 2013 US Composting Council Conference in Florida. My reason for attending was to gain a better understanding of “controlling composting odours” and to attend a composting workshop titled “Advancements in Aerated Static Pile Composting”. The lead presenter of the workshop was Mr. Peter Moon with O2Compost. It became quickly apparent to me during the workshop that the ASP Extended Wedge System that O2Compost had developed was exactly what we needed at our site for the following reasons. It would be:       Easy and quick to integrate within our existing composting operation; Decrease our composting footprint; and speed up our processing time; and Thereby increase our flow-through capacity. It would also be very affordable to retrofit our existing facility; Decrease our month to month operating costs; and Most importantly, it would give us far greater ability to reduce odours and neighbour impacts.
