Supplementary Research Sources

The use of plastics as an energy source was demonstrated on a commercial scale at ICl Materials plastics manufacturing site in Dumfries, UK. This paper covers the preparation and use of pre- and post-consumer plastics as supplementary fuels in a circulating fluidised bed boiler specially designed for co-combustion with coal. Full emissions data on the 15% mixtures of individual plastics with coal are given, together with calculations of thermal efficiencies. Measurements by an independent body (British Coal Research Establishment) confirmed that the co-combustion of coal and plastic reduces some emissions compared with coal alone. Thermal efficiencies of around 80% were achieved and this heat was used effectively during the production of plastics. 7 refs. 

Sometimes when writers of research papers wish to give their readers additional information about their topic or about a particular piece of source material, they include supplementary notes. If you are using the MLA or APA format, these notes should be indicated by using a raised number in your text (The study seemed incomplete at the time of its publication.2) the explanations appear on a page called Notes (MLA) or Footnotes (APA) that immediately follows the end of your essay. If you are using traditional footnote form, simply include the supplementary notes in your list of footnotes at the bottom of the page or in the list of endnotes following your essay s conclusion.
