Metro Vancouver has big plans to convert organic waste to energy or compost  -  custom pizza boxes
Janice Zeilstra dumped organic waste in a bin provided by Surrey city. VANCOUVER —
Fresh red pepper
On the warehouse floor of the Richmond Harvest Power Company, half of the watermelons and a bunch of red grapes are scattered, next to a pile of grain, a few pieces of wood and a bunch of withered lettuce.
In the past, the entire plot would rot in a landfill, spewing methane.
A powerful greenhouse gas.
Into the atmosphere when it rot.
But now everyone seems to be fighting for leftovers because they know that using the potential energy at the top of the carrot can make money for compost or heating tea bags and spaghetti for home or power generation.
The Vancouver Metro is encouraging the trend, hoping to transfer 200,000 tons of organic matter from the dump every year.
By 2015, two landfill sites in the area will ban apple cores, chicken bones, bread skins, eggshells, coffee grounds, tea bags, paper towels, pizza boxes, etc, as Metro aims to increase the recovery and diversion rate from 55 today to 70 by 2015.
"It's all about treating these materials as resources, not waste," said Paul Henderson, manager of the Solid Waste Division at Metro Vancouver.
Dozens of companies and some municipalities are lining up for the challenge for future composters and bio-
Fuel biogas digesters will be as common as bottles and recycling warehouses.
At the Harvest Power compost plant in Richmond, some of Metro's organic kitchen waste has turned into rich dark compost, while the company is building a 30,000-
A ton of aerobic organismsdigester.
This new factory that does not use oxygen will break down "wet and high-calorie" foods like pasta, meat and grease
Mainly from many
Family buildings, restaurants and business facilities-
Produce methane, which will be captured and used to provide enough power to 1,000 households.

The fuel plant in Port Kells will recover energy from the city's organic matter and yard waste to fuel garbage trucks, while Delta's organic matter is treated with Cascade renewable carbon.
Energy from bio-solids at ann island sewage treatment plant
Decomposition of sewage-
Also used for power generation.
"It will definitely be a growing industry," said Steve Aujla, regional business development manager at Harvest . ".
"We definitely need more infrastructure in the next few years.
"But the first step is to educate residents and businesses to throw garbage into green trash cans instead of trash cans.
A garbage study last year found that discarded food accounted for the largest proportion of residential waste in the region, and 39 of the organic matter in the landfill came from a single
32 of family homes, apartments and many other family homesfamily homes. Single-
Family residents are already on board and it is expected that 16 of the 21 cities of the metro will collect organic matter from the roadside by the end of next month.
The concept is simple: Residents can put organic matter and yard garbage in a green trash can, pick it up from the side of the road every week and bring it to the transfer station.
After weighing organic materials, they charge a tip of $63 per ton, which is much lower than the tip of $107 per ton for garbage.
"If we can make it convenient, people usually want to do the right thing," said Greg Moore, president of the Vancouver Metro, the mayor of noble harbor.
"Compost has always existed;
We just do it on a larger scale.
Janice zelstra, a 61-year-old South Surrey resident, never realized how much garbage she had thrown away until she joined 1,000 city pilot projects in 2010.
"At first you really had to stop and think about what it was?
Said Zeilstra.
"I don't even have to think anymore.
"Zeilstra has a small container under her kitchen sink where she will put them before they are taken to the green trash can.
The program was difficult at first, she said, but eventually her husband, two sons, daughter and children in their 90 syear-
The old mother found out.
Now she is rarely filled with trash cans.
"I was very surprised when we first started (composting)
"In fact, there is very little garbage in the trash can," Zeilstra said . ". “It was an eye-opener.
It reminds me of how much we put in the landfill because that's all.
"Now, when I go shopping at the grocery store, I try harder to remember my recyclable bags.
I always have a bag for the Salvation Army or Big Brother in clothes or Nickknacks.
I never throw them in the trash.
It is always recycled to another place.
In Surrey, residents have three trash cans: one for recycling, one for garbage, and the other for green garbage such as lawn newspaper clippings and kitchen garbage.
Rob Costa Zuo, deputy operations manager for Surrey Engineering, said that at the beginning of the pilot project, the city was overwhelmed by calls from residents for help.
But at the end of the day, the participants reduced the kitchen garbage by half.
"We are very surprised because people's habits are deeply rooted," he said . ".
"Once they get the hang of it, it's not a big problem.
"But the hardest work has yet to come: educating multicultural residents
Family buildings, as well as staff at restaurants and supermarkets, separate food waste from garbage.
The Vancouver Metro plans to launch a big campaign next year, acknowledging that it will often be more difficult in multiple cities
Home building due to lack of space and accountability.
With a major collection point, it is always possible for residents to throw everything in a bin --
I don't know who did it.
"Based on the pollution problem, this is a difficult problem to crack," Costanzo said . ".
"Garbage is all taken to a central location, so I wish you all the best to find the culprit.
Similar problems have arisen in commercial facilities.
At Harvest Power, Aujla gapes, as a commercial load, were dumped: There were bloated garbage bags, plastic capsized strawberry containers and glass bottles in the mounting pile.
This load comes from a new business customer who has not yet fully figured out how to classify its waste.
"We have to do this manually," said Aujla, regional business development manager at Harvest . ".
"There are some good things here, so we don't want to repack all of them and send them to the landfill.
"When you say more
Family, that's what you're going to see.
No responsibility.
But Moore insists the system is feasible.
Noble harbor is one of the highest collection rates of organic matter in Vancouver Metro, with city officials working with multiple strata committees
Family homes provide information and check the layout and design of the building to decide where the collection box should be placed.
Although each city will develop its own organic collection system, all waste materials are used for the same purpose: compost or energy.
At the compost plant in Harvest, the garbage in the kitchen is stacked in the pile outside, divided into batches, and then mixed together in a secret company "formula, stayed behind the concrete wall for 8 to 12 weeks.
Oxygen is pumped through a row of perforated pipes under the pile-
This can dry the garbage, reduce the smell, and prevent the production of methane, which will eventually be discharged into the air.
The loader then transports the compost to the "curing area" and the screen extension filters out fine soil and spit out "spills "--
There is still compost of branches and branches.
Such leftovers are sent back to the pile for more compost.
There are many forms of final product: pure compost with high nutrition, 75-per-
Cents of soil mixed with 25-per-
Cents river sand for the gardener, and turf mixture or 50/50 mixture for the gardener.
"No matter what comes into our facility, it has to go out as a high form of compost," Aujla said . ".
"This is sustainable in the environment.
We call it "closed loop" in our industry ".
"It is an endless outreach effort to continue to remind residents what is allowed.
The cleaner we can get them to find sources in the House, the less remains of the landfill.
"Harvest earns revenue through tip and compost sales and wants to work with Metro Northeast cities to build compost sites throughout the region.
At the same time, the Vancouver Metro continues to work with other companies and municipalities to encourage increased capacity for organic products, noting that any new facility must be licensed.
Metro is also considering a ban on disposal or "paid by polluters" compost fees to ensure that the smell is controlled as the facility surges.
Henderson said Metro is working on organic matter projects around the world to determine which ones are valid and which ones are not.
He noted that Ontario is having trouble completing its projects because it is trying to do too much and too fast.
By contrast, Halifax has made great progress in the collection of high organic matter
Use public places.
He said Halifax's model could be high in Vancouver-
Follow the traffic areas such as Stanley Park Haitang.
Costanzo of Surrey predicts that most people will easily adapt to changes once they are in place.
"My feeling is that it's going to be much faster now than it used to be.
Every time we introduce waste transfers on the side of the road, there is a little resistance, "he said.
"But in the last five to six years, the public has asked us to do more. . . most people (believe)
Protecting the environment is an important thing.
