The EESG annual prize is to be awarded to an individual or team working in engineering who have taken significant steps to bridge the gap between an unsustainable present and a more sustainable future. The award will be measured by considering achievement in the development of sustainable engineering projects, products and processes. Where appropriate the achievement of a group of engineers can be recognised with the value of the prize split accordingly or awarded to the lead engineer.
Proposals for a prize award must include:
A proposal should not normally run to more than one side of A4.
Nominations now closed for 2023.
The 2019 EESG prize was awarded to Geoff Bates for his work developing a solution to loss of nitrogen from pastoral farming. The loss of nitrogen is the most significant adverse environmental impact from pastoral farming, particularly dairy farming. The nitrogen harms both water bodies and the atmosphere as well as being a source of greenhouse gasses. It is also a waste of valuable fertiliser.
The nitrogen is lost from the animal’s urine patch and the first challenge was to find a practical robust ‘farmer proof’ method of detecting urine flooded patches of pasture. Of course finding the urine patch is only half the problem and Geoff has also led a considerable research effort to develop treatments to enhance and regulate the activity of different soil bacteria so that the nitrogen in the urine is redirected into grass growth.
The technology developed improves productivity and has opened a whole new field for pastoral farming. This technology has the potential to reduce global GHG emissions by more than the total GHG emission from Geoff’s homeland, New Zealand!
Other developments in Geoff’s career include a device to reduce on farm water use by a third – this device, known as a Dungbuster, is widely used in the New Zealand dairy industry. He also led the team that homologated the first vehicle to meet the FTP Ultra Low Emissions Vehicle standard (in Switzerland).
The 2018 EESG prize was awarded to Dr Kannan for his work on energy planning and policy in Malaysia. This included the production of a code of practice for energy auditing: “MS1525: Code of Practice on Energy Efficiency and use of Renewable Energy for non-residential buildings”. This standard is now widely quoted and used by engineering and architectural professionals.
He has also played a major part in the ASEAN Energy Efficiency & Conservation Best Practices Competition for Energy Efficient Buildings, both as the Malaysian representative on the board of judges and as Chairman from 2004 to 2006.
As well as carrying out energy audits himself, Dr Kannan served as the Chief Project Coordinator for the UNDP-GEF – Malaysian Industrial Energy Efficiency Improvement project from 2005 to 2007. This was the first project that initiated energy auditing in Malaysian industries. A total of 54 industries were audited. As a result of the project, total energy savings from 250 companies implementing energy saving measures was estimated as 3.2 million GJ, giving a CO2 reduction of 944.7 kilotonnes of CO2 annually (i.e., 9.45 million tCO2 over a 10-year period). This work has continued with further industrial establishments leading to additional CO2 reductions.
The 2017 EESG prize was awarded to Professor Hussam Jouhara for his work in developing more efficient energy systems and thus reducing their environmental impact. He combines academic research with commercial knowledge and practical implementation and has filed many patents.
His extensive expertise in designing and manufacturing various types of heat exchanger has resulted in new approaches to the design of recuperators, steam generators and condensers, and flat heat pipes. These designs have since been implemented across various industries including food processing and production, electronic thermal management and low to high industrial waste heat recovery.
Examples include the use of heat pipe technology in nuclear seawater desalination and in ventilation processes.
He is currently working on a home energy recovery unit using the heat pipe technology to pyrolyse domestic waste and supply hot water.
