  A number of homeowners seeking an environmentally friendly alternative to asphalt for paving have experimented with waste vegetable oil as a binder for driveways and parking areas in single-family applications. The earliest known test occurred in 2002 in Ohio, where the homeowner combined waste vegetable oil with dry aggregate to create a low-cost and less polluting paving material for his 200-foot driveway. After five years, he reports the driveway is performing as well or better than petroleum-based materials.
  Shell Oil Company paved two public roads in Norway in 2007 with vegetable-oil-based asphalt. Results of this study are still premature.
  [http://www.halik.biz HALIK Asphalts LTD] from Israel has been experimenting with recycled and secondary road building since 2003. The company is using various wastes such as vegetable 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 [http://www.avellobioenergy.com/ Avello Bioenergy] Inc. Research is being conducted on the asphalt mixture, derived from plants and trees to replace petroleum-based mixes.

  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 centre is running a pilot in the Dutch province of Zeeland with bioasphalt in which the binder of bitumen was substituted by lignin.
  In 2015, French researchers published their results about the usage of microalgaes as a source of asphalt binding material.
