  • RAISING THE BIOSOLIDS BAR: DEVELOPING AN ENVIRONMENTAL MANAGEMENT SYSTEM

    A California sanitation district’s journey through the process of establishing an EMS for biosolids provides valuable insights, especially for agencies battling public acceptance challenges. THE Orange County, California Sanitation District (District) provides wastewater treatment service for more than 2.2 million people. The facility treats approximately 250 million gallons/day of wastewater and ...


  • Human health risk assessment of triclosan in land‐applied biosolids

    Triclosan (TCS; 5‐chloro‐2‐[2,4‐dichlorophenoxy]‐phenol) is an antimicrobial agent found in a variety of pharmaceutical and personal care products. Numerous studies have examined the occurrence and environmental fate of TCS in wastewater, biosolids, biosolids‐amended soils, and plants and organisms exposed to biosolids‐amended soils. TCS has a propensity to adhere to organic carbon in ...

  • Climate change impacts of food waste diversion to anaerobic digesters

    Treating food waste (FW) by anaerobic digestion to recover biogas and biofertiliser is a fantastic opportunity. The biogas is renewable, base-load, non-fossil energy. Using the digestate on land as biofertiliser completes nutrient cycles and conserves soil organic matter. The Part-503 rules protect health and the environment. Existing sludge digesters can be ‘turbo-charged’ by retrofitting ...


  • Advances in Thermophilic Anaerobic Digestion

    ABSTRACTSignificant advances have been made in the knowledge base and practical options for improving thermophilic anaerobic digestion over the past 10 to 15 years. Today, more options exist that promise to enhance the degree of stabilization achieved and finished product quality in new and retrofitted existing processes. In parallel, the body of knowledge regarding pathogen inactivation in these ...

  • Recycling paradise: Composting on maui hits its stride

    Lush, green and ever-inviting, the Hawaiian island of Maui is the vacation destination of choice for more than 2.2 million people each year. Maintaining that pristine, idyllic look comes with a price, however: a year-round growing season yields a massive stream of green waste from non-stop cutting, trimming and pruning. While the resultant green waste was, for years, simply landfilled along with ...

  • MSW Composting in the United States

    Massachusetts became home to two new composting facilities that process MSW and biosolids. Nationally, the total number of operating plants is 19. Since the mid-1980s, BioCycle has been conducting an annual, nationwide survey of municipal solid waste (MSW) composting facilities. From the late 1980s into the early 1990s, when it was projected that landfill capacity would drop and tipping fees ...

  • A Path To Sustainable Infrastructure Solutions

    Today, for the most part, our communities’ infrastructure systems are developed and managed separately, by separate utilities and agencies. Sustainable infrastructure, on the other hand, blurs boundaries between our energy, transportation, water and waste systems to implement complementary strategies that benefit more than one system. Among our most important, and difficult, challenges will ...
