How One NFL Team Will Turn Food Waste Into Renewable Energy
As if the fact that, in the U.S., we waste 40 percent of our food isn’t shocking enough, a recent study by the Proceedings of the National Academy of Sciences finds that total emissions of the potent greenhouse gas methane are almost twice as high in the U.S. as previously thought. More potent than carbon dioxide, methane is a deadly contributor to global warming.
According to the U.S. Environmental Protection Agency (EPA), all that uneaten food accounts for 23 percent of methane emissions as it rots in landfills. Other sources include livestock operations and oil production. And yet, properly captured or, better yet, generated in anaerobic digesters that break down food waste before it ever reaches landfills, methane represents a cleaner energy source for use in heating homes, running engines, and generating electricity. Yet challenges to the widespread availability and use of biogas remain.
Enter FirstEnergy Stadium in Cleveland, where a new partnership with the Cleveland Browns and the Innovation Center for U.S. Dairy has implemented a new system to will divert an estimated 35 tons of stadium food waste from landfills into biodigesters for conversion into energy. The system, called Grind2Energy, is a technology from Emerson’s InSinkErator, a brand many associate with in-sink disposals found in kitchens across the U.S. Far more than an industrial-strength garbage disposal, it’s an integrated system that includes leasing, installation, and service coverage of a closed system that grinds up food waste into a slurry and transports it to an anaerobic digestion facility where it is converted to energy.
Slurry from FirstEnergy Stadium travels to an anaerobic digester operated by Quasar Energy group at the Ohio State University’s Ohio Agricultural Research and Development Center where it will generate enough electricity for a single family for a full year, produce enough natural gas to heat 32 homes for a month and recover enough nutrients to fertilize three football fields of crops.
As well as diverting food waste from landfills, the system at FirstEnergy Stadium will reduce carbon emissions by 28,000 pounds per year, generate enough electricity for a single family for a full year, produce enough natural gas to heat 32 homes for a month, and recover enough nutrients to fertilize three football fields of crops.
The closed nature of the system eliminates odors and enhances kitchen hygiene, decreasing reliance on cleaners and pesticides. The setup creates savings in waste removal because storage tanks can compactly hold three to four weeks of organic slurry. In some cases where such systems are in place, facilities have the opportunity to buy renewable energy and biogas back from anaerobic digester facilities.
The project’s partners hope that the systems’ implementation in a sports arena will fuel public awareness, in keeping with the U.S. Deparent of Agriculture (USDA) and EPA’s U.S. Food Waste Challenge, and encourage producers, manufacturers, communities, and government agencies to reduce and recycle food waste. According to David Krems, Business Development Manager for Grind2Energy, the system’s implementation in Cleveland has generated a lot of interest.
“We have the NFL asking us how do we do this at every NFL stadium," Krems said.
Currently the company has three Grind2Energy systems operational in Ohio, and one deploying in Milwaukee. They’re working to meet high demand for the system in the coming year, especially in the Northeast where many biodigesters are being built, making Grind2Energy a priority for global conglomerate and green housing innovator Emerson. Emerson is satisfying an existing demand. According to Sustainable America’s March 2013 survey, U.S. consumers support “stronger efforts to reduce food waste in restaurants and grocery stores”. And yet the survey found that the perceived importance of these issues lagged behind others—jobs and the economy, for example.
While a food-waste-to-fuel system doesn’t prevent food waste, according to Dana Gunders, a staff scientist with the Natural Resources Defense Council (NRDC), which partnered with the Green Sports Alliance to promote sustainable practices in the sports world, “It’s a great way to reach people who are often difficult to reach through typical environmental channels . . . I think it’s one more block in the domino effect that will eventually lead to change.”
While the widespread integration of anaerobic digesters into the energy grid continues to face hurdles like viable partnerships with energy providers and high initial capital costs for building facilities, they have already proven their value in use by the dairy industry in all 50 states, according to Tom Gallagher, CEO of the Innovation Center for U.S. Dairy. And hopefully the model at FirstEnergy Stadium will be replicated at stadiums, arenas, and other large venues with high levels of food waste across the country.
As director of the NRDC Sports Greening Project and Sustainable America board member Dr. Allen Hershkowitz puts it: “Anaerobic digestion is an important technology that provides great potential to manage our food waste in a more ecologically intelligent way.”
While turning wasted food into energy ranks low on the EPA’s food waste recovery hierarchy, its combined benefits, including the mitigation of greenhouse gas generation, are undeniable. As support for bans on sending food waste to landfills grows, the true potential of anaerobic digestion, through the widespread implementation of systems like Grind2Energy, will become clear.
Turning food waste into renewable energy will become increasingly profitable as relationships between biogas producers and energy providers develop. If we can turn food waste into fuel, we’d go a long way toward reducing some of the harmful linkages between the food and fuel markets in the U.S.

Ola Elvestrun, Norway's environment minister, announced Thursday that it is freezing its contributions to the Amazon Fund, and will no longer be transferring €300 million ($33.2 million) to Brazil. In a press release, the Norwegian embassy in Brazil stated:
Given the present circumstances, Norway does not have either the legal or the technical basis for making its annual contribution to the Amazon Fund.
Brazilian President Jair Bolsonaro reacted with sarcasm to Norway's decision, which had been widely expected. After an official event, he commented: "Isn't Norway the country that kills whales at the North Pole? Doesn't it also produce oil? It has no basis for telling us what to do. It should give the money to Angela Merkel [the German Chancellor] to reforest Germany."
According to its website, the Amazon Fund is a "REDD+ mechanism created to raise donations for non-reimbursable investments in efforts to prevent, monitor and combat deforestation, as well as to promote the preservation and sustainable use in the Brazilian Amazon." The bulk of funding comes from Norway and Germany.
The annual transfer of funds from developed world donors to the Amazon Fund depends on a report from the Fund's technical committee. This committee meets after the National Institute of Space Research, which gathers official Amazon deforestation data, publishes its annual report with the definitive figures for deforestation in the previous year.
But this year the Amazon Fund's technical committee, along with its steering committee, COFA, were abolished by the Bolsonaro government on 11 April as part of a sweeping move to dissolve some 600 bodies, most of which had NGO involvement. The Bolsonaro government views NGO work in Brazil as a conspiracy to undermine Brazil's sovereignty.
The Brazilian government then demanded far-reaching changes in the way the fund is managed, as documented in a previous article. As a result, the Amazon Fund's technical committee has been unable to meet; Norway says it therefore cannot continue making donations without a favorable report from the committee.

An Uncertain Future
The Amazon Fund was announced during the 2007 United Nations Climate Change Conference in Bali, during a period when environmentalists were alarmed at the rocketing rate of deforestation in the Brazilian Amazon. It was created as a way of encouraging Brazil to continue bringing down the rate of forest conversion to pastures and croplands.
Government agencies, such as IBAMA, Brazil's environmental agency, and NGOs shared Amazon Fund donations. IBAMA used the money primarily to enforce deforestation laws, while the NGOs oversaw projects to support sustainable communities and livelihoods in the Amazon.
There has been some controversy as to whether the Fund has actually achieved its goals: in the three years before the deal, the rate of deforestation fell dramatically but, after money from the Fund started pouring into the Amazon, the rate remained fairly stationary until 2014, when it began to rise once again. But, in general, the international donors have been pleased with the Fund's performance, and until the Bolsonaro government came to office, the program was expected to continue indefinitely.
Norway has been the main donor (94 percent) to the Amazon Fund, followed by Germany (5 percent), and Brazil's state-owned oil company, Petrobrás (1 percent). Over the past 11 years, the Norwegians have made, by far, the biggest contribution: R$3.2 billion ($855 million) out of the total of R$3.4 billion ($903 million).
Up till now the Fund has approved 103 projects, with the dispersal of R$1.8 billion ($478 million). These projects will not be affected by Norway's funding freeze because the donors have already provided the funding and the Brazilian Development Bank is contractually obliged to disburse the money until the end of the projects. But there are another 54 projects, currently being analyzed, whose future is far less secure.
One of the projects left stranded by the dissolution of the Fund's committees is Projeto Frutificar, which should be a three-year project, with a budget of R$29 million ($7.3 million), for the production of açai and cacao by 1,000 small-scale farmers in the states of Amapá and Pará. The project was drawn up by the Brazilian NGO IPAM (Institute of Environmental research in Amazonia).
Paulo Moutinho, an IPAM researcher, told Globo newspaper: "Our program was ready to go when the [Brazilian] government asked for changes in the Fund. It's now stuck in the BNDES. Without funding from Norway, we don't know what will happen to it."
Norway is not the only European nation to be reconsidering the way it funds environmental projects in Brazil. Germany has many environmental projects in the Latin American country, apart from its small contribution to the Amazon Fund, and is deeply concerned about the way the rate of deforestation has been soaring this year.
The German environment ministry told Mongabay that its minister, Svenja Schulze, had decided to put financial support for forest and biodiversity projects in Brazil on hold, with €35 million ($39 million) for various projects now frozen.
The ministry explained why: "The Brazilian government's policy in the Amazon raises doubts whether a consistent reduction in deforestation rates is still being pursued. Only when clarity is restored, can project collaboration be continued."

Alternative Amazon Funding
Although there will certainly be disruption in the short-term as a result of the paralysis in the Amazon Fund, the governors of Brazil's Amazon states, which rely on international funding for their environmental projects, are already scrambling to create alternative channels.
In a press release issued yesterday Helder Barbalho, the governor of Pará, the state with the highest number of projects financed by the Fund, said that he will do all he can to maintain and increase his state partnership with Norway.
Barbalho had announced earlier that his state would be receiving €12.5 million ($11.1 million) to run deforestation monitoring centers in five regions of Pará. Barbalho said: "The state governments' monitoring systems are recording a high level of deforestation in Pará, as in the other Amazon states. The money will be made available to those who want to help [the Pará government reduce deforestation] without this being seen as international intervention."
Amazonas state has funding partnerships with Germany and is negotiating deals with France. "I am talking with countries, mainly European, that are interested in investing in projects in the Amazon," said Amazonas governor Wilson Miranda Lima. "It is important to look at Amazônia, not only from the point of view of conservation, but also — and this is even more important — from the point of view of its citizens. It's impossible to preserve Amazônia if its inhabitants are poor."

Looming International Difficulties
The Bolsonaro government's perceived reluctance to take effective measures to curb deforestation may in the longer-term lead to a far more serious problem than the paralysis of the Amazon Fund.
In June, the European Union and Mercosur, the South American trade bloc, reached an agreement to create the largest trading bloc in the world. If all goes ahead as planned, the pact would account for a quarter of the world's economy, involving 780 million people, and remove import tariffs on 90 percent of the goods traded between the two blocs. The Brazilian government has predicted that the deal will lead to an increase of almost $100 billion in Brazilian exports, particularly agricultural products, by 2035.
But the huge surge this year in Amazon deforestation is leading some European countries to think twice about ratifying the deal. In an interview with Mongabay, the German environment ministry made it very clear that Germany is very worried about events in the Amazon: "We are deeply concerned given the pace of destruction in Brazil … The Amazon Forest is vital for the atmospheric circulation and considered as one of the tipping points of the climate system."
The ministry stated that, for the trade deal to go ahead, Brazil must carry out its commitment under the Paris Climate agreement to reduce its greenhouse gas emissions by 43 percent below the 2005 level by 2030. The German environment ministry said: If the trade deal is to go ahead, "It is necessary that Brazil is effectively implementing its climate change objectives adopted under the [Paris] Agreement. It is precisely this commitment that is expressly confirmed in the text of the EU-Mercosur Free Trade Agreement."
Blairo Maggi, Brazil agriculture minister under the Temer administration, and a major shareholder in Amaggi, the largest Brazilian-owned commodities trading company, has said very little in public since Bolsonaro came to power; he's been "in a voluntary retreat," as he puts it. But Maggi is so concerned about the damage Bolsonaro's off the cuff remarks and policies are doing to international relationships he decided to speak out earlier this week.

Maggi, a ruralista who strongly supports agribusiness, told the newspaper, Valor Econômico, that, even if the European Union doesn't get to the point of tearing up a deal that has taken 20 years to negotiate, there could be long delays. "These environmental confusions could create a situation in which the EU says that Brazil isn't sticking to the rules." Maggi speculated. "France doesn't want the deal and perhaps it is taking advantage of the situation to tear it up. Or the deal could take much longer to ratify — three, five years."
Such a delay could have severe repercussions for Brazil's struggling economy which relies heavily on its commodities trade with the EU. Analysists say that Bolsonaro's fears over such an outcome could be one reason for his recently announced October meeting with Chinese President Xi Jinping, another key trading partner.
Maggi is worried about another, even more alarming, potential consequence of Bolsonaro's failure to stem illegal deforestation — Brazil could be hit by a boycott by its foreign customers. "I don't buy this idea that the world needs Brazil … We are only a player and, worse still, replaceable." Maggi warns, "As an exporter, I'm telling you: things are getting very difficult. Brazil has been saying for years that it is possible to produce and preserve, but with this [Bolsonaro administration] rhetoric, we are going back to square one … We could find markets closed to us."
