Bioasphalt

Bioasphalt is an asphalt alternative made from non-petroleum based renewable resources .

These sources include sugar , molasses and rice , corn and potato starches , natural tree and gum resins, natural latex rubber and vegetable oils, lignin , cellulose , palm oil waste, coconut waste, peanut oil waste, canola oil waste, dried sewerage effluent and so on. [1] It can also be made from waste vacuum tower bottoms produced in the process of cleaning used motor oils, which are normally burned or dumped into land fills. [2]

Non-petroleum based bitumen binders can be colored, which can reduce the temperatures of roads and reduce the heat . [3]

Petroleum, environmental, and heat concerns

Because of concerns over Peak oil , pollution and climate change , 2003 , non- petroleum alternatives have become more popular. This leads to the introduction of biobitumen alternatives that are more environmentally friendly and nontoxic.

For millions of people living in and around cities, heat islands are of growing concern. This phenomenon describes urban and suburban temperatures that are 1 to 6 ° C (2 to 10 ° F) hotter than nearby rural areas. Elevated temperatures can affect communities by increasing peak energy demand, air pollution costs, and heat-related illness and mortality. Fortunately, there are some common-sense measures that can be made to reduce the size of the road. [4] [5]

History and implementation

Asphalt made with vegetable oil based binders was patented by Colas SA in France in 2004. [6] [7]

A number of homeowners looking for an environmentally friendly alternative to asphalt for paving the road with a kitchen and parking area. The earliest known test in the year 2002 in Ohio, where the homeowner combined with a low-cost and low-pollution paving material for his 200-foot driveway. After five years, it is better than petroleum-based materials. [ quote needed ]

Shell Oil Company paved two public roads in Norway in 2007 with vegetable-based oil asphalt. Results of this study are still premature. [8]

HALIK ASPHALTS LTD. From Israel has been experimenting with recycled and secondary road building since 2003. The company is using various types of fats & oils , wax and thermoplastic elastomers to build and repair roads. The results reported are so far satisfying.

On October 6, 2010, a bicycle path in Des Moines, Iowa , was paved with bio-oil based asphalt through a partnership between Iowa State University , the City of Des Moines, and Avello Bioenergy Inc. , derived from plants and trees to replace petroleum-based mixes. [9] Bioasphalt is a registered trademark of Avello Bioenergy Inc.

Dr. Elham H. Fini, at North Carolina A & T University, has been spearheading research that has successfully produced bio asphalt from swine manure.

Since November 2014 the Dutch Wageningen University & Research Center is running a pilot in the Dutch province of Zeeland with bioasphalt in which the binder of lignin was replaced by lignin . [10] [11]
Petraviam , founded in 2017, has developed a proprietary blend of recycled and natural compounds.
