Global Landfill Crisis

Visualizing the Global Landfill Crisis

In a world that generates 2 billion tonnes of waste every year, landfill management has become a global concern.

Reusing, remanufacturing, and recycling materials have become essential in minimizing pollution and greenhouse gas emissions.

The above infographic from Northstar Clean Technologies highlights how waste management has become a multibillion-dollar industry opportunity.

The Largest Contributor to Global Waste

The world produces enough solid waste to fill over 800,000 Olympic sized swimming pools every year. Waste generated per person averages 0.74 kilograms per day.

Below, we show the regions that generate the most waste, measured in millions of tonnes. Asia, Europe, and North America are the top waste generators, respectively.

Region2016 Waste Generation (Millions of tonnes)2030 Waste Generation (P)2050 Waste Generation (P)
Middle East and North Africa 129177255
Sub-Saharan Africa174269516
Latin American and Caribbean 231290369
North America 289342396
South Asia334466661
Europe and Central Asia392440490
East Asia and Pacific 468602714

The U.S. ranks number one in per-capita waste by country, producing 12% of the world’s trash despite only accounting for 4% of its population.

On average, a U.S. resident produces over three times as much waste as a Chinese resident and seven times more than a person living in Ethiopia.

Approximately half of the 230 million tonnes of yearly waste in the U.S. will meet its final resting place in one of the more than 2,000 active landfills across the country. That’s the equivalent to 22 billion plastic bottles every year, or enough office paper to construct a 12-foot-high wall from Los Angeles to Manhattan.

With solid waste steadily climbing over the last decades, many landfills across the country are already running out of space.

Construction Waste

A big part of landfill waste comes from the construction industry.

In a 2018 research, the U.S. Environmental Protection Agency (EPA) found that total waste from construction-related projects was double that of municipal waste from households and businesses.

Putting this into perspective, 12 million tons of used asphalt shingles are dumped into landfills across North America every year, equivalent to ∼100 million plastic bags.

As a result, solid waste landfills are already the third-largest source of human-related methane emissions in the U.S., behind energy production and agriculture.

SourceU.S. Methane Emissions
Natural Gas and Petroleum30%
Enteric Fermentation (digestive process in ruminant animals)27%
Municipal Solid Waste Landfills 15%
Manure Management 9%
Other 9%
Coal Mining 7%
Other Landfills 2%

*Percentages may not add to 100 due to rounding

In this context, repurposing waste has not only become essential to minimizing waste, but also to creating new business opportunities going forward.

A Multibillion-Dollar Industry Opportunity

The global waste recycling market is expected to grow considerably in the coming years as awareness about environmental impacts increases.

By 2027, it is forecast that the global waste recycling services market will have reached a value of $80.3 billion.

Northstar Clean Technologies aims to become the leading recovery and reprocessing company for asphalt shingles in North America.

Emissions per Capita of the Top 30 U.S. Investor-Owned Utilities

Approximately 25% of all U.S. greenhouse gas emissions (GHG) come from electricity generation.

Subsequently, this means investor-owned utilities (IOUs) will have a crucial role to play around carbon reduction initiatives. This is particularly true for the top 30 IOUs, where almost 75% of utility customers get their electricity from.

This infographic from the National Public Utilities Council ranks the largest IOUs by emissions per capita. By accounting for the varying customer bases they serve, we get a more accurate look at their green energy practices. Here’s how they line up.

Per Capita Rankings

The emissions per capita rankings for the top 30 investor-owned utilities have large disparities from one another.

Totals range from a high of 25.8 tons of CO2 per customer annually to a low of 0.5 tons.

Let’s start by looking at the higher scoring IOUs.

TransAlta

TransAlta emits 25.8 tons of CO2 emissions per customer, the largest of any utility on a per capita basis. Altogether, the company’s 630,000 customers emit 16.3 million metric tons. On a recent earnings call, its management discussed clear intent to phase out coal and grow their renewables mix by doubling their renewables fleet. And so far it appears they’ve been making good on their promise, having shut down the Canadian Highvale coal mine recently.

Vistra

Vistra had the highest total emissions at 97 million tons of CO2 per year and is almost exclusively a coal and gas generator. However, the company announced plans for 60% reductions in CO2 emissions by 2030 and is striving to be carbon neutral by 2050. As the highest total emitter, this transition would make a noticeable impact on total utility emissions if successful.

Currently, based on their 4.3 million customers, Vistra sees per capita emissions of 22.4 tons a year. The utility is a key electricity provider for Texas, ad here’s how their electricity mix compares to that of the state as a whole:

Energy SourceVistraState of Texas
Gas63%52%
Coal29%15%
Nuclear6%9%
Renewables1%24%
Oil1%0%

Despite their ambitious green energy pledges, for now only 1% of Vistra’s electricity comes from renewables compared to 24% for Texas, where wind energy is prospering.

Based on those scores, the average customer from some of the highest emitting utility groups emit about the same as a customer from each of the bottom seven, who clearly have greener energy practices. Let’s take a closer look at emissions for some of the bottom scoring entities.

Utilities With The Greenest Energy Practices

Groups with the lowest carbon emission scores are in many ways leaders on the path towards a greener future.

Exelon

Exelon emits only 3.8 tons of CO2 emissions per capita annually and is one of the top clean power generators across the Americas. In the last decade they’ve reduced their GHG emissions by 18 million metric tons, and have recently teamed up with the state of Illinois through the Clean Energy Jobs Act. Through this, Exelon will receive $700 million in subsidies as it phases out coal and gas plants to meet 2030 and 2045 targets.

Consolidated Edison

Consolidated Edison serves nearly 4 million customers with a large chunk coming from New York state. Altogether, they emit 1.6 tons of CO2 emissions per capita from their electricity generation.

The utility group is making notable strides towards a sustainable future by expanding its renewable projects and testing higher capacity limits. In addition, they are often praised for their financial management and carry the title of dividend aristocrat, having increased their dividend for 47 years and counting. In fact, this is the longest out of any utility company in the S&P 500.

A Sustainable Tomorrow

Altogether, utilities will have a pivotal role to play in decarbonization efforts. This is particularly true for the top 30 U.S. IOUs, who collectively serve 60 million Americans, or one-fifth of the U.S. population.

Ultimately, this means a unique moment for utilities is emerging. As the transition toward cleaner energy continues and various groups push to achieve their goals, all eyes will be on utilities to deliver.

The National Public Utilities Council is the go-to resource to learn how utilities can lead in the path towards decarbonization.

The Road to Decarbonization: How Asphalt is Affecting the Planet

The U.S. alone generates ∼12 million tons of asphalt shingles tear-off waste and installation scrap every year and more than 90% of it is dumped into landfills.

Road to Decarbonization - How Asphalt is Affecting the Planet

The Road to Decarbonization: How Asphalt is Affecting the Planet

Asphalt, also known as bitumen, has various applications in the modern economy, with annual demand reaching 110 million tons globally.

Until the 20th century, natural asphalt made from decomposed plants accounted for the majority of asphalt production. Today, most asphalt is refined from crude oil.

This graphic, sponsored by Northstar Clean Technologies, shows how new technologies to reuse and recycle asphalt can help protect the environment.

The Impact of Climate Change

Pollution from vehicles is expected to decline as electric vehicles replace internal combustion engines.

But pollution from asphalt could actually increase in the next decades because of rising temperatures in some parts of the Earth. When subjected to extreme temperatures, asphalt releases harmful greenhouse gases (GHG) into the atmosphere.

Emissions from Road Construction (Source) CO2 equivalent (%)
Asphalt 28%
Concrete18%
Excavators and Haulers16%
Trucks13%
Crushing Plant 10%
Galvanized Steel 6%
Reinforced Steel6%
Plastic Piping 2%
Geotextile1%

Asphalt paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively. Furthermore, 75% of single-family detached homes in Canada and the U.S. have asphalt shingles on their roofs.

Reducing the Environmental Impact of Asphalt

Similar to roads, asphalt shingles have oil as the primary component, which is especially harmful to the environment.

Shingles do not decompose or biodegrade. The U.S. alone generates ∼12 million tons of asphalt shingles tear-off waste and installation scrap every year and more than 90% of it is dumped into landfills, the equivalent of 20 million barrels of oil.

But most of it can be reused, rather than taking up valuable landfill space.

Using technology, the primary components in shingles can be repurposed into liquid asphalt, aggregate, and fiber, for use in road construction, embankments, and new shingles.

Providing the construction industry with clean, sustainable processing solutions is also a big business opportunity. Canada alone is a $1.3 billion market for recovering and reprocessing shingles.

Northstar Clean Technologies is the only public company that repurposes 99% of asphalt shingles components that otherwise go to landfills.
