40 years experience delivering customized material sorting and handling solutions Design, engineer, manufacture, and install turnkey recovery facilities MSW, RDF/SRF, anaerobic digestion, mixed recyclables, construction and demolition, and composting Global footprint with engineering, manufacturing, and sales offices around the world Award-winning installation base

Four World-Class Brands: One Integrated Solution Worldwide system provider for waste processing needs Optical Sorting Nashville, TN Air Separation Amsterdam, NL Anaerobic Digestion Lafayette, CA

U.S. MSW Market Opportunity Only 34.5% of MSW Generated is recycled Even with Single Stream Recycling available, up to half of recoverable recyclables are thrown away 25-30% of US homes currently don t have access to curbside recycling lower barriers to entry A majority of the reusable resources in U.S. MSW remain untapped

Capturing Lost Commodities 72% of HDPE-N, 69% of PET bottles and 45.4% of aluminum cans are discarded. Current State of Waste Management in the U.S. BHS recovers more than 90% of these commodities in our MSW systems. 54% (135M tons) remain untapped

Capturing Lost Commodities 35.4% 64.6% 24.26 64.6% Paper 8.8% 28.95 8.8% 91.2% 4.8% 34.69 Plastics Of 100M tons of plastic and paper waste generated annually, 53M tons are currently unrecovered

The Dirty MRF Fighting Perception of the Dirty MRF Processes around 20 tons per hour Offers 8-10% recovery Requires Significant Labor Is not profitable

The Advanced Mixed Waste MRF IS HIGHLY AUTOMATED

The Advanced Mixed Waste MRF PROCESSES 70+ TONS PER HOUR

The Advanced Mixed Waste MRF FEATURES HIGH RECOVERY RATES

Montgomery, Alabama: Before and After No recycling 100% to landfill Before Entire state produced one load of PET per month After 60% recovery, city-wide 100% participation Produces 15 loads of PET per month

Why Do This? Collection costs account for 50-70% of total MSW processing costs Costs Higher Transportation Capital Lower Higher - Multiple Stops Transportation Variable Cost Lower One Stop More Labor Less Yes Multiple MRFs No Usually Transfer Station No Additional Green Waste Included Other Factors Yes Education Minimal Yes Confusion No Sometimes Waste-to-Energy Integrated

Answering the Demand

Optical Sorting Film Recovery

Optical Sorting Fiber Recovery

Optical Sorting: X-ray Technology Extends the reach of organics recovery Identifies material by atomic properties Removes inert (glass, rock, ceramic) from organics Result is clean organics ready for AD or compost NRT s X-ray technology identifies material that is hidden from site, identifying at the atomic level. It is ideal for removing contaminants from compost.

TruSort with DXRT

High Solids Anaerobic Digestion Complete dry fermentation, high solids AD System 21 day or less, digestion cycle Biogas economically converted to electricity, heat and/or transportation fuels (CNG) Option for In-Vessel Composting (IVC) for ammonia scrub through compost maturation SMARTFERM offers two platforms: prefabricated steel or cast-in-place concrete digesters. System sizes range from 5,000 to over100,000 TPY Acceptable Materials Food waste, organic fraction of MSW (OFMSW) and green waste Inorganic and inert materials do not impact system operation Shredding/size reduction not required

Carbon Negative Fleets ANAEROBIC DIGESTION FACILITY Carbon Negative Fleets BIOGAS CONDITIONING AND COMPRESSION

In-Vessel Composting (IVC) Post-digester treatment to mature compost from the digestate. Fully enclosed tunnel system to accelerate and control the natural aerobic breakdown and create a high-quality, ready to bag compost in less than 28 days. Optional 3-4 day IVC to remove most odor-causing ammonia before transport and finishing Benefits of Composting Digestate Moisture reduction Odor minimization PFRP (sanitization) of compost Quality compost for sale
