Multimaterial Processing Includes Organics

Bulk Handling Systems (BHS) began installing its multimaterial waste sorting system at the Newby Island Material Recovery Facility (MRF) and Composting Operation in San Jose, owned by Republic Services. The system, will process 110 tons/hour and consists of four processing lines: residential single-stream, commercial single-stream, commercial dry recyclables and commercial wet recyclables. The organic fraction recovered from the wet recyclables will be transported to Zero Waste Energy Development Company’s anaerobic digestion and composting facility in San Jose. BHS expects the recovery rate to exceed 75 percent on the commercial lines and 95 percent on the residential single stream line. For project background, see “Creating Infrastructure For Commercial Waste Diversion,” August 2011.

Compostable Products Purchasers Criteria

Developed by the Sustainable Biomaterials Collaborative (SBC), the BioSpecs for Purchasers include both mandatory specifications and additional, desirable criteria for compostable serviceware. The mandatory specifications include a minimum biobased content requirement and verification of commercial compostability by the Biodegradable Products Institute (BPI) or other third-party certifier. Desirable criteria give credit to products with more biobased content and recycled material, that lack genetically modified organisms, are sustainably manufactured and offer other environmental benefits. BioSpecs for Purchasers and sample bid sheets assist food service professionals in bidding on compostable serviceware and may be accessed at

 Sustainable Biosolids

Synagro Technologies, Inc., has signed a 20-year lease agreement with the Charlotte County Public Works Solid Waste Division to develop a regional biosolids and green waste Bio-Recycling Center at the county’s Zemel Road landfill near Punta Gorda, Florida. Synagro will design, finance, build and operate a covered windrow composting facility that will recycle approximately 50,000 tons of biosolids annually. “We are proud to work with Charlotte County to provide a sustainable recycling solution for the region,” said Pamela Racey, Vice President of Sales and Development at Synagro. “By transforming natural waste materials into valuable Class AA compost, we’re enabling regional biosolids generators to meet civic goals while fulfilling a critical environmental requirement of local communities.”

Rehrig Pacific Company's Container Asset Recovery Tracking System (CART)

Rehrig Pacific Company's RFID technology allows tracking of lost/stolen containers in real time.

Tracking Collection Carts

Rehrig Pacific Company announced upgrades to its Container Asset Recovery Tracking System (CARTS) software program for municipalities and private waste haulers. CARTS enables real-time collection service tracking and daily account audits utilizing Rehrig’s RFID technology. The upgrades also allow companies to track lost and/or stolen containers in a particular service area in real time.

New Biobased Polymers

NatureWorks, which markets Ingeo PLA biopolymers, and BioAmber, a biotechnology/chemical processor, have joined forces to develop “a new family” of compounded biopolymer resins. NaturWorks will utilize the compounded Ingeo grades for food service ware applications, expanding the property range of the products in terms of flexibility, toughness, heat resistance and drop-in processability on existing manufacturing equipment. BioAmber owns PLA/PBS compounding intellectual property to produce renewable chemicals that are cost competitive with their petrochemical equivalents, according to the joint venture companies.

Garden Socks Hit The Airwaves

Filtrexx International is airing a new commercial for its GardenSoxx, a mesh tube filled with growing media such as compost that functions as an alternative to raised bed gardening. The ad campaign — selling 50-feet of sock and a filler to load in the media — is targeted to home gardeners. Commercials began airing in early May on the Verizon network, HGTV, the Food Network and other venues in markets including Southern California, Chicago, Dallas, Tampa and New York City/New Jersey.

Biosolids Drying Via Compost System

Guodian Northeast Environmental Protection Industry Group, Ltd. has selected Siemens Industry Automation Division to supply an IPS composting system using the new Mechanically Enhanced Biodrying (MEB) process for the Shenyang Wastewater Treatment Plant (WWTP) in China. It will be the largest IPS composting facility ever built and will serve three existing WWTPs and one new one. The Shenyang plant is designed to dewater 1,000 wet metric tons/day of material from 20 percent solids to 65 percent solids without adding heat. The MEB process does not require a significant amount of carbon-rich amendment. The installation will enable all of the treatments plants to comply with a new law that biosolids must be a minimum of 60 percent solids for land application and/or landfill disposal. Commissioning of the system is scheduled in the fall of 2012.
