A novel drainage system and animal unit flooring system has been developed which maximises comfort and welfare of animals housed on it and at the same time allows separation of urine and faeces, reducing the conversion of urea to ammonia ( by separating the urease in the faeces from the urune) and thus reducing nitrogen release to the atmosphere. The system is based on plastic void forming units originally designed for storm water control purposes. These units are covered with a perforated rubber foam, made from recycled foam waste, and a high strength textile. Cattle, goats and horses have been preference tested on this surface and have been shown to prefer it to traditional straw covered flooring. Cattle spend a long time lying down on this surface and this can potentially increase milk yields. A robot is used to clean faeces the floor continually and if it encounters an animal it will avoid it and return to that place later . Urine is filtered through the textile and is available for use as a liquid fertiliser and the drier faecal matter can be stored with much less threat to the environment. This poster will review the construction of the system and report on the work done on both survival of mastitis-causing organisms in the fabric and foam layers and the drainage behaviour of liquids expressed from the foam by animal movements.

Professor of Environmental Technology
Sheffield, United Kingdom
I am Professor Alan P Newman of Coventry University, UK. I hold Masters degrees in Chemistry and in Environmental Law and a PhD in Environmental Engineering. I worked for a total of 16 years as an environmental regulator and 17 years as a full-time academic at Coventry University. When I retired from the University in 2005 I had just completed 3 years as head of the Environmental Science subject group. Since my retirement I continued to work part-time at the University and to maintain my research interests. I currently hold the appointment of visiting professor. I am interested in adsorption systems for water purification ,various aspects of environmental law and, particularly, in Low Impact Development (Sustainable Drainage Systems in the UK). Here my interests have, for a long time, been pervious pavements but more recently filter drains and green roofs. I have probably published more in the 10 or so years since my retirement than in the 10 years prior to it. Such are the pressures of a full time job! Recently I have become involved with the work of the Chesterfield Canal Trust, an organization dedicated to the restoration of the historic Chesterfield Canal, where I volunteer for work in the Trust’s archive and am keen to ensure that documents relating to the canal’s recent history and the ongoing restoration task are preserved for future generations. I tend to spend spring and autumn at our house in Spain where I am in the process of creating a home cinema in the basement.
