  • Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)

    The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

  • Composting In rural Alaska

    Gardeners, communities and commercial enterprises have proven that composting works in Alaska, especially given large quantities of fish waste and diminishing landfill capacity. ALASKA is two and a half times larger than the largest state in the lower 48 states. Over half of the entire state’s population lives within the municipality of Anchorage. Many Alaskan villages can only be reached ...

  • Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama

    The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

  • Agrior Project, Chaudière-Appalaches, Quebec, Canada

    Compost Drying Application Agrior makes high value organic fertilizers by composting a mixture of animal manure and organic municipal and industrial wastewater treatment sludge. A DRY-REX low-temperature drying system was designed and installed at Agrior’s facility to dry the mixture into high-quality compost. The low-temperature process results in the drying of the manure with minimal ...

  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • Effect of compost-, sand-, or gypsum-amended waste foundry sands on turfgrass yield and nutrient content

    Received for publication July 19, 2008. To prevent the 7 to 11 million metric tons of waste foundry sand (WFS) produced annually in the USA from entering landfills, current research is focused on the reuse of WFSs as soil amendments. The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall ...

  • Effects of peat moss substitution with arboretum and greenhouse waste compost for use in container media

    Plugs of impatiens (Impatiens walleriana Hook.f.), salvia (Salvia splendens Sellow ex Roem. & Schult.), and vinca (Catharanthus roseus (L.) G. Don) were transplanted into containers filled with commercial Sphagnum peat moss plus perlite medium (Sunshine Mix #1) or arboretum and greenhouse waste compost (CT), Sphagnum peat moss (PS), and perlite (PE) medium at percentages of (by vol.) 50:50 ...

  • Rice straw composting and its effect on soil properties

    In Egypt, recycling rice straw and organic wastes is of great concern as well as improvement of soil properties. Rice straw compost could improve both organic waste recycling and soil quality. The aim of this study was to evaluate the effect of the rice straw compost, with or without water treatment residuals (WTR), on soil chemical properties and dry weight of canola. The results showed that the ...
