Waste360 Global Waste Management Symposium

February 14, 2022

Save the date!  Waste360 is hosting its Global Waste Management Symposium, February 14-17, 2022 at the Hyatt Regency Resort & Spa in Indian Wells, California.

The program is taking shape and will feature numerous sessions on solid waste and materials management, such as waste minimization and reuse, landfill operation and design, organics diversion/composting/anaerobic digestion, elevated temperature landfills/subsurface reactions, climate change, greenhouse gas emissions, sustainable materials management, wastes from energy production (e.g. coal ash), waste containment and geosynthetics, odor emissions and management, leachate treatment, recycling and material markets, landfill gas production, waste-to-energy, waste characterization, and more!

GWMS services the needs of landfill owners and operators, as well as their engineers and the consultant and vendor communities. Join this broad coalition of participants that also includes:

  • Facility Owners and Operators
  • Local / State / Federal Agencies
  • Researchers
  • Waste Service Companies
  • Vendors / Suppliers
  • Trade Organizations
  • Solid Waste Generators
  • Students

Sponsorship opportunities are currently available.

Keep watch for EPA’s grant applications to help reduce food loss and waste

July 15, 2021

EPA anticipates awarding up to $2 million in total AD funding. Individual projects could be in the range of $50,000-$200,000 for the funding period of two years.

 

The U.S. Environmental Protection Agency (EPA) is seeking applications on Grants.gov for projects from states, tribes, territories, and non-profit organizations to help reduce food loss and waste and divert food waste from landfills by expanding anaerobic digester (AD) capacity in the United States.

To qualify, EPA is asking that your project application achieve one or more of the following objectives:

  • Develop new or expand existing AD capacity for processing food waste.
  • Demonstrate solutions and/or approaches for increasing food waste AD utilization that can be replicated by other communities, governments, or other entities.
  • Support state, Tribal, and/or local government programs that seek to use AD to increase their food waste diversion rates.

State, local, Tribal, interstate, and intrastate government agencies and Non-profit organizations (as defined by 2 CFR Part 200) may apply. In addition, up to approximately $800,000 of the estimated total will be set-aside specifically for awards to the following organizations:

  • S. territories;
  • Tribal governments;
  • Tribal colleges and universities; or
  • Eligible organizations located in persistent poverty counties.

Applications are due by October 7, 2021. Additional information is available on the EPA site or by requesting grant assistance at .

September 14, 2020

WASTE EXPO 2020 is now a digital event called WasteExpo Together Online, and will be held September 14-17.

The conference will feature a business forum and 20 virtual sessions on food recovery, composting, organics recycling, including the following presentations by SCS Professionals.

The Food Recovery Forum (FRF) will cover the progress of food waste prevention and reduction, including these presentations by SCS professionals  at the Reducing Food Waste and Increasing Recovery in Municipal, Regional, and State Programs sessions on Tuesday, September 15 – 2:15 pm – 3:00 pm EST:

  • SCS Vice President Michelle Leonard, will co-present with Judi Gregory, Go2Zero Strategies on Food Recycling and Rescue – Los Angeles County’s Three-Pronged Approach 
  • SCS Project Manager, will cover Community Based Social Marketing (CBSM) for Food Waste Prevention and Food Recovery Programs in Santa Clara County and Central Contra Costa County

At WasteExpo Together Online (WTO) these two sessions will air on Wednesday, September 16:

  • SCS Vice Presidents, Pat Sullivan and Ray Huff, will discuss Comparison of Organic Waste Management Options in Terms of Air Quality and GHG Impacts at the Anaerobic Digestion, Composting, Successful Case Studies, and Comparison of Organic Waste Management  session – 12:30 pm EST
  • SCS Project Director, Tracie Bills, will moderate the session on A Balancing Act: Municipalities Talk Waste & Recycling (Ginger Spencer – Phoenix, AZ; Tori Carle – Charlotte, NC; John Welch – Dane County, WI) – 1:30 pm EST

SCS Engineers helps public and private entities evaluate their organic waste streams and the applicability of composting, anaerobic digestion to their specific plans…

January 11, 2016

Food-Waste-CompostingOrganic materials management is of high interest in our industry.  This interest is being driven by state and city regulations and other government policies for diversion of organics from disposal facilities.  Five states have food waste disposal bans, including Massachusetts, California, Vermont, Connecticut and Rhode Island, which are in various stages of implementation.  Some cities have food waste disposal bans, including San Francisco, Seattle, Portland (Oregon), and Austin.  Many states and government agencies have organic diversion policies and goals; e.g., USEPA has a 50 percent reduction goal for food waste sent to landfills, nationwide, by 2030.

SCS is helping public and private entities evaluate their organic waste streams and the applicability of established and emerging technologies (e.g., composting, anaerobic digestion) to their specific communities and circumstances.  Current and recent project examples include the following:

  • Compost facility design, permitting, and operations at for five compost facilities in the Northeast, located in Massachusetts, Rhode Island and New Jersey. For the Sam White and Sons, Inc. compost facility located in Middleboro, Massachusetts, operations services include provision and use of a truck-mounted mixer to mix food and leaves, and a Komptech X-60 compost turner to turn the windrows. Sam White sells the finished product through its network of purchasers.  SCS has had “boots on the ground” at this facility since 2013, gaining real-world experience with open-windrow composting of various organic materials.
  • Organics recycling plan for Eastern Placer County, California. SCS is currently assisting the County develop an organics recycling plan, which includes evaluating technologies (e.g., in-vessel composting, aerated static pile (ASP) composting, anaerobic digestion) and recommending an approach to fit their specific needs and circumstances.
  • Characterization of diverted waste materials for composting at the University of Maryland (UM).  This was a one-week residential pilot project at Easton Hall on campus. SCS hand-sorted the materials and compiled the data and results into a letter report.
  • Evaluation of organic waste processing facilities for the Town of Smithtown, New York. SCS is researching and evaluating the impacts of organic waste processing facilities (OWPFs), and identifying the Best Management Practices (BMPs) for operating and regulating indoor OWPFs. SCS’s work will support the Town’s efforts to develop and implement ordinance amendment(s) that would permit and regulate such facilities in the Town.

SCS-Engineers-Environmental-Remediation-Construction

SCS is actively pursuing work in the organics materials management sector and has a staff devoted to staying current with the latest trends and technologies.  SCS can evaluate, design, permit, construct and operate organics facilities, using varying technologies.  Compost technologies that SCS is considering for implementation include:

  • Open, turned windrows
  • Aerated static piles with covers
  • In-vessel systems

Anaerobic digestion (AD) technologies that SCS is considering for implementation include high solids (dry) or low solids (wet) systems.  High solids/dry systems are applicable for food and yard waste.  Dry systems for food and yard waste generally use tunnels, which are gas-tight, concrete, garage-like chambers and are loaded using front-end loaders.  Low solids/wet systems are applicable for manure, sludges, and liquid industrial waste.  Wet systems generally use vessels, which are mixed and are fed using pumps.
