Abstract

The term biosolids does little to convey the broad range of material properties associated with its production and use, unless that's the reason they spelled it with a trailing s. Biosolids are routinely applied to land in many forms, as a liquid, thick slurry, semi-solid cake, compost, alkaline amendment, dried pellet, or soil blend - each with distinct handling characteristics. The uses for biosolids products are also wonderfully diverse in objective, fertiliser or soil amendment, and in land form, (e.g. forest, farrrh mine, or park). Designing a product delivery system which accounts for the handling characteristics of the biosolids, the application site characteristics, and the application objectives can be challenging" To meet this challenge, there are a wide variety of technologies and approaches available, which are limited only by your imagination. The trick then is to match the correct technology to the application. In the development of the Greater Vancouver Regional District's Residuals Management Program, we have been faced with many unconventional biosolids application challenges in silviculture, rangeland, and reclamation projects, using a changing variety of biosolids types and products. This has given us cause, or an excuse, to investigate, develop, or test a wide variety of biosolids application methods and technologies. In this paper, we will discuss the results of our trials and tribulations, and suggest which of these technologies are best suited to what types of biosolids applications. It is our hope that some of this information will be helpful to other biosolids recycling practitioners, -and perhaps inspire others to innovate, or perhaps not.
