Pyrolysis liquids are being developed for fuel and chemical applications. As these developments proceed, liquids are increasingly being transported by air, water, rail and road. To this end, this report addresses the legislative requirements and regulations for the safe transport of pyrolysis liquids.

Pyrolysis liquids are not listed on the UN approved carriage list for dangerous or hazardous goods; therefore, the most appropriate not otherwise specified [N.O.S.] classification was determined. The classification is:

UN 1993 FLAMMABLE LIQUID, N.O.S. (Fast Pyrolysis Liquid), 3, 1º(a), 2º(a)

This classification should be used on all packages containing biomass derived fast pyrolysis liquids. The packaging group is ''1'' or ''X'', as is commonly used. Labelling and packaging are vital requirements of transportation of all quantities of pyrolysis liquids. Protocols for the labelling of packages and containers of all sizes are given with the aim of compliance with transport regulations in the EU, Canada and the USA. In conjunction with the requirements for packaging and labelling, guidance on the details to be enclosed on the transportation documents are given, with appropriate MSDS for the liquids. Guidance on the handling of pyrolysis liquids and storage are given and preliminary procedures for the treatment of spills.

Further work is required to determine the degradability of pyrolysis liquids, appropriate transportation codes also need to be derived for other pyrolysis liquids fractions, and those derived from non-biomass materials, e.g. plastics, wastes, etc. Further work is required to determine procedures for dealing with spills.
