  • Fresh look at organics bans and waste recycling laws

    Approximately 40 percent of food produced in the U.S. is wasted annually. At a time when millions of Americans are food insecure and thousands of farmers struggle to stay afloat, the negative consequences of wasting food extend far beyond the environmental impacts and loss of resources that could have been otherwise allocated. There are great opportunities for food waste reduction at the federal ...

  • Organics Recycling In North Carolina

    A recent study by state agency analyzed organic materials recycled since 2011, as well as food waste recovered in 2015. Findings show substantial organics recycling capacity. The North Carolina Department of Environmental Quality (NC DEQ) released a study in June 2016 analyzing the organic materials recycled since 2011, as well as food waste recovered in 2015. The facility reporting ...

  • Adsorptive removal of As(III) from aqueous solution by waste litchi pericarps

    The present study investigated the removal of arsenite anions (AsO33−, referred to as As(III)) from aqueous solutions by waste litchi pericarps (LPs). Influential factors such as the adsorbent dose, contact time, solution pH, and initial As(III) concentration were investigated. The optimum conditions for As(III) adsorption by the LPs occurred at a contact time of 60 min, adsorbent dose ...

  • What is Zero Waste?

    Over the past five years or so, leading solid waste and recycling organizations, communities and businesses across the country have increasingly embraced Zero Waste. Zero Waste policies and programs establish practical ways to eliminate waste and safely reuse, recycle or compost discarded products and packaging. However, there has been confusion in the marketplace due to the many definitions of ...

  • Characterization of biochar prepared from slow pyrolysis of Jordanian olive oil processing solid waste and adsorption efficiency of Hg2+ ions in aqueous solutions

    Solid waste from Jordanian olive oil processing (OOSW) was used to prepare biochar samples by slow pyrolysis at terminal temperatures of 350, 450, 550 and 630 °C; henceforth known as BC-350, BC-450, BC-550 and BC-630, respectively. These samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction, ash content, moisture content and ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Q&A: OMI’s Dr. Laura Haupert Discusses Eco-Friendly Odor Solutions for Landfills

    The waste management arena is continually challenged when it comes to fighting odors, which often become a major nuance for neighbors. Landfills all throughout the U.S. also have to contend with finding the right odor-abatement solutions that are both effective, and safe for employees and surrounding communities. In the following “Clearing the Air” Q&A, we speak with Dr. Laura ...

  • Evaluation of the energetic potential of sewage sludge by characterization of its organic composition

    The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...

  • SRF plant now operational in South West France

    Commissioning of a new waste processing plant in Mende, South West France is now complete. Following almost two years of planning, design, engineering and construction, Environnement 48 began shredding Commercial and Industrial (C&I) waste to produce a Solid Recovered Fuel (SRF), this month. Already one of the region's most established waste management companies and a member of the French ...

  • Savanna wastewater treatment plant case study

    Performance History and Discussion Jackson, MS selected In-Pipe Technology Company, Inc. for the Savanna WWTP with goals to reduce the quantity of waste sludge for disposal and control FOG in the collection system and at the plant. Jackson, the capital and largest city in Mississippi, was looking for ways to reduce sludge expenses from polymer to hauling and disposal fees. In-Pipe ...

  • Determining anaerobic degradation kinetics from batch tests

    Data obtained from a biomethane potential (BMP) test were used in order to obtain the parameters of a kinetic model of solid wastes anaerobic degradation. The proposed model considers a hydrolysis step with a first order kinetic, a Monod kinetic for the soluble organic substrate degradation and a first order decay of microorganisms. The instantaneous release of methane was assumed. The ...

  • State Aims to Modernize Mindsets Along with Trash Policies, Facilities

    By July 1, 2016, the Department of Energy and Environmental Protection (DEEP) is set to revise the state-wide solid waste management plan to include a strategy to divert, through source reduction, reuse and recycling, 60 percent of solid waste generated in Connecticut after January 1, 2026. That figure is more than double the waste currently diverted from landfills. Doubling the amount of waste ...

  • Do you Have Sludge Build Up in Your Pond?

    Smelly and Muddy Water Ponds and lakes naturally accumulate sludge and nutrients that lead to eutrophication and eventually pond or lake death. Natural succession is driving all lakes and ponds to become meadows and eventually forest. To slow or reverse this process and maintain a lake or pond beneficial microbes are critical. These beneficial microbes improve water quality by ...

  • Flux-step method for the assessment of operational conditions in a submerged membrane bioreactor

    A flux-step method was used for monitoring the pressure variation in a solids separation membrane at different operating conditions. A submerged membrane bioreactor pilot plant, used during the short-term tests, was used to purify actual restaurant wastewater. The influence of membrane backwash and relaxation on the variation of pressure variation was also evaluated. In order to reduce the ...

  • Effect of sodium salt on anaerobic digestion of kitchen waste

    The effect of different sodium salt concentration on anaerobic digestion of kitchen waste was investigated. The methane production performance, the corresponding methane production model and sodium salt inhibition model were studied, and the degradation efficiency was analyzed. With the increase of sodium salt concentration, the methane yield and the maximal methane production rate decreased ...
