How We Think Green.

From “Think Green” comes “Act Green”. This is how we’re turning waste into a resource and
putting sustainability at the core of our business.

RECYCLING

Recycling more is a worthy goal–for homeowners, businesses and communities. Today, we’re North America’s largest residential recycler, managing almost 14 million tons of material that is recycled or reused each year. It’s a story we can all take pride in.

Single-Stream Recycling

We are committed to making recycling easier, more efficient and more productive.
Single-stream recycling, where all recyclables are mixed together in one collection
bin, is perhaps the best example of that philosophy in action. In addition to being easy
on consumers and businesses, this approach delivers added efficiency by reducing
vehicle miles for collection trucks and related tailpipe emissions.

In recent years, we have purchased more than a million tons of additional recycling
capacity, much of which is designed to expand our single-stream service area.

MATERIAL IN-FEED

Trucks are weighed and directed to the tip floor. Material is unloaded, inspected and stored, until it's ready to be fed to a conveyor.

PRE-SORT STATIONS

Sorters remove rejected items and film, which is vacuumed away. Bulky materials, inert materials and large pieces of plastic are also removed and in some cases sent for additional recycling.

CORRUGATED SCREENS

Material crosses a triple-deck Old Corrugated Cardboard (OCC) screen, which skims off the OCC from the rest of the material stream. The OCC floats over the screen, where it is inspected before being conveyed to storage bunkers.

PAPER MAGNET

Material left in the main flow is now mostly containers. These materials flow over a paper magnet, designed to extract paper from the stream. It uses powerful vacuum technology to hold two-dimensional paper flat to the conveyor, while round three-dimensional containers continue on the flow.

NEWSPAPER SCREENS

At this stage, the materials pass through a series of disc screens, which separate containers, cans and bottles from old newspapers and remove any remaining fiber material.

STEEL MAGNET

Next, a steel magnet removes and stores ferrous materials from the material stream.

GLASS SORTER

Whole glass bottles are broken and fed via conveyor belt to the glass crusher, which
crushes the glass and moves it to a
storage area.

OPTICAL SORTING

Bottles and cans that make it through the glass sorting area run through a series of optical scanners. These scanners separate out the last of the paper from the commingled stream, as well PET soda/water bottles, HDPE milk/detergent bottles, and aseptic milk/ juice cartons. Each are stored separately.

BAILING

Interior storage bunkers
accumulate large quantities
of each separated material
stream, which are subsequently
processed in ultra-high-efficiency
equipment for compaction
into "bales" for shipment to
end-use markets.

EDDY CURRENT

The remaining material is delivered
to an eddy current that automatically
separates aluminum by use of
a rare earth electro current, which
repels the aluminum over a baffle
where it drops to a chute and is
blown into a bunker for storage.

FINISHED PRODUCT

Forklifts move the bales to a finished
product storage area where they are
checked for quality.

SHIPPING

Bales are shipped to end users around the
world via truck, rail or ship, where they are
used as feedstock for new products.

Campaigns for Recycling

Perhaps the best way to improve recycling is to communicate how easy and effective it is to consumers. In addition to our ongoing Recyclebank partnership that provides valuable incentives to our residential customers to recycle, we've joined with Keep America Beautiful to help get the message out about recycling. The result is a multi-faceted advertising campaign designed to reinvigorate the recycling "brand", and generate awareness and understanding for recycling. We've also developed the Recycle Often. Recycle Right.SM campaign to provide consumers with the basic knowledge and tools for incorporating proper recycling into every aspect of their lives.

Ultimately, we want to alter the way Americans recycle by transforming it into a daily social norm. That's a big task. To get there, these campaigns feature an array of messaging and media channels to provide strong calls-to-action for everyone.

E-cycling

Sometimes the hardest challenges can lead to the biggest breakthroughs. Nowhere is that more evident than with our E-Cycling programs.

E-Cycling

Here, we're building our capacity to take on difficult-to-recycle materials such as electronics and partnering with our customers and outside experts to do it safely.

By 2012, our network included more than 200 collection depots in North America, gathering phones, batteries, laptops and other manufactured products. From there, eight Product Recovery Centers process what's been gathered - all have earned the Responsible Recycling (R2) and
E-Cycling Industry Operating Standard (RIOS) certification are eStewards and ISO 9001 certified.

RENEWABLE ENERGY

Our commitment to renewable energy is taking form in two distinct ways – our landfill-gas-to energy (LFGTE) and waste-to-energy (WTE) facilities. Together, they’re producing enough energy each year to power more than a million homes. That puts us well on our way to our goal of powering two million households by 2020.

Landfill-Gas-to-Energy

It’s a beautiful thing, actually, to turn waste into power. As waste decomposes in a landfill, a natural by-product is landfill gas. More than 20 years ago, we realized this gas could be captured and burned as fuel. We are now able to convert the gas into electricity or an alternative transportation fuel.

The benefits of landfill gas are both proven and compelling. This clean-burning energy-source is generated close to the end-user. Looking ahead, we’re taking a leading role in developing Next Generation Landfill technology. The goal? Accelerate the decomposition of organic waste by increasing moisture content. This will help in creating more usable space AND more efficient landfill gas-to-energy utilization.

HOW LANDFILL-gas-TO-ENERGY WORKS

The cycle begins with the collection of residential and commercial waste. Recyclables are separated, and the remaining waste is then transported to Waste Management landfills for permanent disposal.

Much of this waste, including food, paper and cardboard, is organic in nature. Bacteria digest this organic waste and produce methane gas and carbon dioxide as natural by-products.

At the compression facility, the landfill gas is de-watered, filtered and pressurized.

The methane gas is recovered via a series of wells drilled into the landfill. These wells are connected by a common pipe system that collects the gas and transports it to a nearby compression facility.

The gas is piped to an electricity generating plant, onsite or offsite, where it is used as fuel to turn engines or turbines to generate electricity. Landfill gas may also be piped offsite to industrial customers for use as an alternative fuel source.

LANDFILL-GAS-TO-ENERGY At A Glance

  • Corbon Dioxide

    An energy source that, when used, directly prevents atmospheric pollution

  • 470,000 Homes

    Landfill gas is currently being supplied to more than 135 projects, providing more than 615 megawatts of energy per year (enough to power 470,000 homes)

  • 2.5 Million Tons of Coal

    Energy supplied by landfill gas replaces over two and a half million tons of coal per year


Waste-to-Energy

Another way to help conserve fossil fuels is by converting trash to create thermal energy. We’re at the forefront of this approach, as well. Our wholly owned subsidiary, Wheelabrator Technologies, owns or operates 17 waste-to-energy plants and five independent power production facilities that can convert seven million tons of waste into steam annually, which can generate up to 4.75 billion kilowatts of electricity. That's enough energy to power nearly 750,000 homes.

There’s another waste-to-energy benefit, too. The residue ash produced from burning waste takes up 90% less space than trash in a landfill. According to the EPA, the power produced by waste-to-energy plants has less environmental impact than almost any other source of electricity.

WASTE-TO-ENERGY At A Glance

  • Wheelabrator Since 1975

    Wheelabrator opened the first commercially successful waste-to-energy facility in Saugus, Mass., in 1975. Three decades later, it is still operating

  • 669 Megawatts

    17 waste-to-energy facilities are currently in operation with a combined processing capacity of more than 23,000 tons/day of municipal solid waste and an electric generating capacity of 669 megawatts (MW)

  • Atmospheric Gases

    Studies have shown that waste-to-energy plants prevent the release of millions of tons of greenhouse gases

LANDFILL HABITATS

Sustainability takes many forms at Waste Management. Perhaps the most visible symbols are our landfills themselves. In many different ways, in locations across the country, we’re transforming the way a community and its residents view the presence of a landfill.

Habitat Conservation

Our long-term goal is to create 100 certified wildlife habitat sites and protect 25,000 acres by the year 2020. So how are we doing? We've actually already met that goal, a decade ahead of schedule. Rather than stop there, we'll continue to make habitat development a priority by shifting focus to smaller, more urban sites where wildlife preservation is a valuable community amenity.

The reasons for looking at landfills as a natural resource are many. Our customers, and the communities in which we operate, want more sustainable ways to deal with what they discard. Turning landfills into natural resources is a logical extension of that idea. Our employees view these efforts with a source of pride, as well.

FLEET

Most people have never seen a Waste Management landfill. Or a Waste Management recycling facility. But most everybody has seen a Waste Management truck. What they might not know is that our fleet of vehicles has become one of our most important–and impactful–environmental solutions.

Converting to Natural Gas Vehicles

Committing to a more sustainable future starts with a good, hard look at our own operations. One of the first places we looked was at our fleet of collection vehicles. After several years of serious experimentation, we determined that converting our fleet to natural gas is the best option to improve efficiency and reduce greenhouse gas emissions.

So convert we have. Within a few years of that commitment, some 2,000 natural gas collection vehicles have been put into operation-making ours the largest heavy-duty natural gas fleet in the country. And we're just getting started.

NATURAL GAS FLEET At A Glance

  • CO2 Natural Gas Fleet Reduces Carbon Dioxide

    Switching to a natural gas fleet reduces carbon dioxide (CO2) emissions and delivers improvement in per-mile emissions of nitrogen oxides (NOx) and particulate material

  • Natural Gas Public Fueling Stations

    Our investment in natural gas vehicles also includes public fueling stations for our fleet and other local natural gas fleets


Altamont LNG Plant

The conversion to a natural gas fleet involves more than just our vehicles. It also involves how and where we get the natural gas to fill those vehicles. Our Altamont Landfill in California was one of the nation's first to install turbines to convert landfill gas to electricity. Today, Altamont produces up to 13,000 diesel gallon equivalents of clean-burning natural gas to power approximately 300 solid waste and recyclable material collection vehicles on a daily basis. Use of this near-zero carbon fuel eliminates nearly 30,000 tons of carbon dioxide emissions annually.

To bring it to our vehicles involves a state-of-the-art vacuum extraction system and a network of wells to capture the gas. The collected landfill gas is then refined into high quality renewable natural gas. The power to run the plant is also derived from landfill gas. Residue contaminants are removed and flared to minimize discharge to the atmosphere. Converting landfill gas to a green alternative to fossil fuel is the ultimate closed-loop approach to managing historic waste streams.

Altamont At A Glance

  • Renewable Liquified Natural Gas

    Collection vehicles fueled by Altamont RLNG (renewable liquified natural gas) produce 95% fewer carbon emissions than diesel-fueled trucks.

  • Altamont LNG Largest in the World

    The Altamont landfill's gas-to-RLNG transportation fuel plant is the largest in the world.

  • Saves 2.5 Million Gallons of Diesel

    Using LNG from the Altamont facility is estimated to save 2.5 million gallons of diesel fuel per year and reduce GHG emissions by 30,000 tons/year.

WASTE CONVERSION

President John F. Kennedy once challenged our nation to reach the moon by saying we should do so, not because it’s easy, but because it’s hard. That’s how we feel about pursuing new technologies for reusing waste. And we’re pursuing them with much the same skill and passion of a moon landing.

Plastics Recovery

Imagine driving a car powered by plastic bags, old computer cases or even broken plastic toys. That's the concept behind our investment in green technology designed to convert hard-to-recycle plastics into crude oil.

In simple terms, it turns a waste stream into a value stream. Best of all, it's more than an investment - it's a viable solution that's now coming to fruition at a first-of-its-kind facility near Portland, Ore.

WASTE CONVERSION At A Glance

  • Plastics High Value Resource

    Plastics traditionally considered as non-recyclable are now being converted into a high value, beneficial resource

  • Crude Oil Converted Into Gasoline

    The synthetic crude oil can be marketed for use at refineries, where it can be turned into ultra low-sulfur diesel, gasoline and even new plastics


SpecFUEL

Innovation can take many forms and can come from unexpected places. Waste Management's SpecFUEL is a perfect example. In a throw-away society, SpecFUEL makes use of materials that would typically be discarded.

SpecFUEL is a clean-burning alternative fuel intended to be combusted with or replace coal and petroleum coke used for heat in cement kilns and industrial boilers and by utilities. SpecFUEL is formulated using post-recycled paper and plastics that have been extracted from municipal solid waste (MSW). In the end, SpecFUEL complements our recycling programs and diverts even more materials from landfills. That's a good thing for all of us.

  • Coal Industry

    SpecFUEL is ideal for industries using coal to produce energy or steam (chemical, pulp and paper, textiles, pharmaceutical and metal manufacturing)

ORGANICS

Many communities and businesses across the country are working to develop convenient and cost-effective systems to recycle organic materials. To increase food-waste recycling, we’re working with customers in the food industry to develop innovative programs that are cost-effective and can make organics recycling easier and more efficient than ever.

Food, Yard Waste and Other Organics Recycling

We've developed a network of company-operated compost and organics processing facilities, partners' facilities and third-party operations to manage more than two million tons of organics, converting it to beneficial uses such as mulch, compost and even energy. Just as important are the organics processes and programs we put in place for our customers. We're helping them capture a growing source of organic materials - in ways that make it easy to increase diversion and enhance their sustainability.
