Wall Street’s Next Big Play Is Garbage

The green push by the U.S. and state governments is turning trash into treasure and boosting the firms that handle America’s garbage.
Shares of the biggest players in the U.S. trash business, Waste Management and Republic Services, have traded at record highs since President Biden signed the climate, tax and healthcare bill in August. A recent decline notwithstanding, the stocks are popular picks on Wall Street to ride the sustainability boom higher.

“They’re sitting in this extraordinary position,” said Michael Hoffman, an analyst at investment bank Stifel. “Garbage will be on the forefront.”
Efforts to reduce greenhouse-gas emissions and to reuse materials are making it more profitable to mine landfills for energy and sift through refuse for the hot commodities of the green economy, such as detergent bottles and cardboard boxes.
WM and Republic are building plants to isolate methane from the fumes emitted by rotting garbage and pipe it into the natural-gas grid to be burned in power plants, furnaces and kitchens. They are also equipping recycling facilities with the latest in automation to better sort and process materials for the consumer-goods companies that are under pressure to keep their packaging out of landfills and the ocean.
Landfill owners are forecasting hundreds of millions of dollars in additional profit from rising demand for recycled materials and tax incentives for making energy from emissions that would otherwise seep into the atmosphere.
“We’re blessed to be sitting right in the middle of a megatrend,” Republic Chief Executive Jon Vander Ark said. “We used to think about getting 5% top-line growth a year; now we’re in double-digit top-line growth mode.”
Republic, which has 206 active landfills, has a joint venture with a unit of BP to install gasworks at 43 of its dumps. The Phoenix firm has 65 landfill-gas plants. Some feed utility pipelines. Others generate electricity on site.
Republic is also spending about $275 million to build four polymer-processing facilities that will sort the plastic it collects kerbside and turn it into flakes for new bottles and jugs.
Vander Ark said consumer-product companies face minimum post-consumer-content mandates in California, Washington and other states, as well as their own sustainability goals. Republic’s first plastics plant is scheduled to open later this year in Las Vegas. Customers lined up.
“There’s fighting among customers about who gets what,” Vander Ark said.
Analysts say one risk is that adding exposure to volatile markets for commodities and renewable-fuel credits might spook investors interested in the steady and predictable profits involved in dumping garbage into landfills. Executives say the sustainability businesses are supplementary and moneymakers even when commodity prices are low, like now.
“Yes, there’s a year-over-year impact, but recycling is still profitable,” said Tara Hemmer, WM’s chief sustainability officer. “It still is one of our highest return-on-capital investments.”
WM, which operates more than 250 landfills, is in the second year of a four-year plan to spend $1.2 billion adding 20 trash-gas plants as well as $1 billion expanding and automating its recycling business.
The Houston company expects new and upgraded facilities to increase its recovery of reusable materials 25% by 2025. Having machines do the dirty work also cuts labor costs, executives say.
A lot of hard-to-fill jobs will be replaced by optical sorters, which use infrared cameras to spot valuable materials in the jumble and blow the desirable bits into separate bins with pinpoint puffs of air, Hemmer said.
“In the past we might have had mixed-paper bales that had cardboard embedded in them,” she said. “Now we’re able to pull more of that cardboard out, it goes in the cardboard bale, and the price point on cardboard is much higher than mixed paper.”
WM says the blended commodity value from its automated material recovery facilities is about 15% higher per ton. Not only do the machines amass more of the valuable stuff, the company says the material emerges cleaner and can fetch more than messy bales.
The recycling investments will add $240 million to its bottom line over the next four years, WM says. It has higher expectations for its gas business.
WM says it will boost landfill-gas output eightfold and generate more than $500 million in additional earnings before interest, taxes, depreciation and amortisation through 2026.
That profit forecast assumes two prices associated with every million British thermal units of gas. WM is counting on the actual fuel selling for $2.50, which is lately about the price of gas from geologic wells. Another $23.50 is anticipated from renewable-fuel credits, which is in line with recent trading, according to energy-information firm Platts.
The outlook doesn’t count the $250 million or more of tax credits WM expects for building new gas plants.
Last year’s climate bill sweetened the economics of trash gas. A federal proposal to offer additional credits for biogas projects that produce power for electric vehicles could make the incentives even stronger.
Waste-company executives and analysts say that many are worth building anyway and that the incentives make it economical to install gasworks at smaller, less-gassy landfills.
“Landfill gas is essentially the only scalable biofuel that doesn’t have a food-for-fuel trade-off,” said Goldman Sachs analyst Jerry Revich. “These projects don’t need any subsidies, but they will take the free money.”

The federal budget has rattled property investors. But the biggest mistake isn’t the tax changes, it’s the conclusion many are drawing from them.
The recent budget has forced a reckoning for property investors.
Negative gearing now restricted to new residential builds, the CGT discount gone and on paper, the numbers look different.
And many investors are responding by pivoting toward yield, prioritising cash flow over capital growth in a way that property strategists say misses the point entirely.
“The debate has shifted to yield versus growth as if they are opposing forces,” says Abdullah Nouh, founder of Melbourne-based buyers’ agency Mecca Property Group. “But that framing is itself the mistake.”
Nouh, who works with high-net-worth families and investors on long-term acquisition strategy, argues that capital growth remains the primary driver of genuine wealth creation and that the post-budget environment has made quality assets more important, not less.
The numbers make his case plainly. An additional $500 per week in rental income is welcome. A prestige asset appreciating by $1 million over a market cycle is transformative.
These are not equivalent outcomes, and portfolios built around yield at the expense of location and land value tend to generate income while wealth stands largely still.
The more nuanced shift Nouh is seeing among sophisticated investors is a move toward assets where both outcomes can be engineered simultaneously – established homes on substantial land in quality locations, where the existing dwelling can be repositioned, rental returns improved, and the underlying land value compounds independent of what sits on it.
For investors with existing equity, commercial property is also entering the conversation in a more serious way.
Prestige industrial assets, medical centres and long-leased essential retail offer income profiles that residential property in most capital city markets cannot currently match: longer lease terms, tenants covering outgoings, and greater predictability than the residential tenancy cycle.
“The investors who build lasting wealth are rarely the ones who chased yield or growth exclusively,” says Nouh.
“They are the ones who built a strategy they could sustain – one that generated enough income to hold quality assets through multiple cycles while those assets compounded in value.”
The budget has changed the settings. It has not changed the fundamentals.
