Recycling and Waste Management
October 03-04, 2019 | Melbourne, Australia
Almost one billion scrap tires are generated and
recycled, creating almost $8 billion of revenue
worldwide. With stricter regulations, the market for the
recovery and recycling of scrap tires is increasing at the
rate of 4.5% annually. The three largest segments are fuel,
civil engineering applications, and ground rubber markets.
Recently, tire-derived aggregates (TDAs) are being widely
used for civil engineering applications. The rubber used
in manufacturing tires were found to adsorb toxic organic
compounds and heavy metals. In addition, steel wires in
tires are capable of removing phosphorus present in the
environment. Various sizes of scrap tires can be used in a
golf course as a substitute for aggregates and an adsorbent
for removal of pesticides and fertilizers. A 20-cm thick tire
rubber layer was found to be capable of removing ≥ 90%
for 37 out of 51 pesticides evaluated. By using scrap tires
for the mitigation of pesticides and fertilizers, golf courses
may be able to realize the dual benefits of waste utilization
and reduced environmental contamination. A preliminary
design was performed for a golf course where one million
scrap tires stockpiled in a landfill are used. TDAs are good
materials for stormwater management systems. TDA
can hold twice more water and provide 75% lower cost
than stone when used as underground water storage.
TDA can also be used as an eco-friendly zone by treating
roadway runoff in the bioswale. Recently, more steel wire
exposed TDA was proposed for phosphorus removal from
agricultural runoff. More case studies will be presented.
Speaker Biography
Jae Park is a Professor of the Civil and Environmental Engineering
Department at the University of Wisconsin-Madison. He received
a B.S. in Civil Engineering at Yonsei University in 1977 and a M.S. in
Environmental Engineering at Seoul National University in 1979. He
worked as a consulting engineer in Korea and Australia for two years
after serving two and a half years of military service. He received a
Ph.D. in Public Health Engineering at the University of Newcastle upon
Tyne, United Kingdom in 1985. He worked as a research engineer at the
Sanitary and Environmental Health Research Laboratory, University of
California, Berkeley from 1985 to 1988.
Since he joined University of Wisconsin-Madison in 1988, he has taught
environmental engineering courses such as water treatment plant design,
wastewater treatment plant design, biological treatment, physical/
chemical treatment, hazardous waste management, solids and hazardous
waste engineering, industrial water pollution control, etc. His research is
in the areas of water quality management and river restoration; biological
treatment of toxic organic compounds; biological nutrient removal,
hazardous waste treatment; mass transport in the environment; fate
of organic compounds in water and wastewater treatment processes;
computer-aided design of water and wastewater treatment plants; and
reuse of scrap vehicle tires as a contaminant sorbent. He has published
one book and over 200 journal articles. He has been a consultant to many
governments, institutions, utilities, and companies fromall over theworld.
