DWR is pleased to present a special event on turning food waste into fuel. Clean World is a company located in Sacramento and collects waste food from Sacramento restaurants to turn into compressed natural gas. They will be giving two presentations on their process on America Recycles Day in the Resources Building Auditorium. The presentations will bracket the lunch hour with one presentation at 11: 30 AM and the second at 12:45 PM to 1:30 PM.
The company "Clean World" launched its Sacramento biodigester in December, 2012. The Sacramento biodigester received attention last year when Clean World announced that the first phase of the project, began accepting food waste in early December. In June 2013, the biodigester began providing compressed natural gas (CNG) to an adjacent CNG fueling station operated by Atlas Disposal.
Now Clean World has broken ground on an expansion project that will boost the 10,000-tons-per-year facility by 300 percent to 40,000 tons per year, making it the largest commercial high-solids food waste digester in the United States. The official groundbreaking was held June 24, 2013.
In addition, in May 2013 Clean World broke ground on a 20,000-ton-per-year biodigester at the University of California, Davis. That project has been designed to blend landfill gas and digester gas to produce electricity for UC Davis. In 2012, the company also placed into service the American River Packaging biodigester in Natomas, Calif., which produces electricity for the box plant.
When complete, the Sacramento biodigester is expected to produce 700,000 gallons per year of renewable CNG. The Clean World facility will produce 8 million gallons a year of organic soils and fertilizer products and generate 1 million kilowatts of electricity to be used to power the facility and the adjacent fueling station.
Clean World's anaerobic digestion technology, developed at the University of California, Davis, and built in California, uses natural microbes to break down organic waste, generating biogas and other forms of renewable energy.
Friday, November 15 is America Recycles Day, a national recycling event. Since the first America Recycles Day in 1997, ARD has helped millions of Americans become better informed about the importance of recycling and buying products made from recycled materials.
Through America Recycles Day, the National Recycling Coalition helps volunteer coordinators organize events in hundreds of communities nationwide to raise awareness and educate people about the benefits of recycling.
And it's working. Americans today are recycling more than ever.
In 2006, according to the EPA, every American generated about 4.6 pounds of waste daily and recycled approximately one third of it (roughly 1.5 pounds).
The rate of composting and recycling in the United States rose from 7.7 percent of the waste stream in 1960 to 17 percent in 1990. Today, Americans recycle around 33 percent of their waste.
It's not just about waste: it is about energy as well.
In 2007, the amount of energy saved from recycling aluminum and steel cans, plastic PET and glass containers, newsprint and corrugated packaging was equivalent to:
- The amount of electricity consumed by 17.8 million Americans in one year.
- 29 percent of nuclear electricity generation in the U.S. in one year.
- 7.9 percent of U.S. electricity generation from fossil fuels in one year.
- 11 percent of the energy produced by coal-fired power plants in the United States
- The energy supplied from 2.7 percent of imported barrels of crude oil into the United States
- The amount of gasoline used in almost 11 million passenger automobiles in one year.
Recycling also reduces costs to businesses and creates jobs. The American recycling and reuse industry is a $200 billion dollar enterprise that includes more than 50,000 recycling and reuse establishments, employs more than 1 million people, and generates an annual payroll of approximately $37 billion.
In California, waste recycling and management rank higher on the economic and job creation scale comparable to the state's entertainment industry. Through recycling, a mainstream industry comprising 5,300 business operations and employing more than 85,000 workers has been created in California. Overall, $4 billion in salaries, along with $10 billion worth of goods and services, is generated each year.
America Recycles Day Highlights the Benefits of Recycling
Recycling helps to conserve natural resources and reduce greenhouse gas emissions that contribute to global warming. According to the EPA, recycling one ton of aluminum cans saves the energy equivalent of 36 barrels of oil or 1,655 gallons of gasoline.
Saving Energy on America Recycles Day
If a ton* of cans is a little too much to visualize, consider this: recycling a single aluminum can saves enough energy to power a television for three hours. Yet, every three months, Americans toss enough aluminum into landfills to rebuild the entire U.S. fleet of commercial airplanes, according to the National Recycling Coalition.
*There are approximately 35 aluminum cans to a pound. As there are 2240 lbs in a ton then there are about 80,000 aluminum cans in a ton!
