In time for Earth Day on April 22, the City of Vancouver announced a new three-phase curbside compost pick-up program for single-family homes. According to the City, phase one will allow families to add their vegetable and fruit scraps, tea bags, coffee grounds and filters to their yard trimming bins. In early 2011, we’re supposed to see this service extended to include all food scraps including meats, fish, dairy, bread, cereal products and food-soiled paper. The compost will be handled by a commercial composting facility, Fraser Richmond Soil & Fibre, which can generate the right amount of heat and moisture to break down this matter appropriately and in a timely manner.

As of yet, this program is unfortunately not available for apartment dwellers, although the City is working on a plan for Metro Vancouver to add collection to multi-family units and businesses. The good news is that there are some private grassroots initiatives starting up in Vancouver that are addressing the commercial composting challenge. Growing City for example started servicing the downtown Vancouver area last year.

There are significant reasons why cities, such as Vancouver, are finally jumping on the composting bandwagon. While composting initially costs more than land-filling, over the long-term, the benefits will outweigh these costs. Organic material from single-family homes in Vancouver makes up over 35 percent of garbage that ends up in our landfill. By diverting it to a local composting facility instead, we can reduce a large source of landfill-generated greenhouse gases, extend the life of our landfill, and generate a valuable resource for the community in the form of premium soil and mulch. What’s more, this industry generates additional jobs, and word has it that Fraser Richmond will also add technology that will allow for the production of renewable energy as of 2011. You can find out more on this through their parent company, Harvest.

Significant municipal infrastructure progress, such as adding new composting plants and programs, is good news for the alternative packaging industry. Such infrastructural change makes it easier to introduce innovative new packaging materials (made from agricultural fibers for example) as alternatives to traditional plastic packaging. It is one thing to find alternatives to plastic packaging, but if the infrastructure isn’t there to support that switch, it is more difficult to promote change.

When I’m at the grocery store check-out till, I often wonder about the courageous customers that place their unprotected lettuce, tomatoes, or apples on the conveyor belt where hundreds of other items, including meats, poultry and fish, and sticky bakery items or dusty cans have already been transferred that day. What’s more, the cashier needs to touch every item and handle the cash in-between. Of course, we have the option of bringing our own reusable produce bags. Either way, it does beg a discussion about the benefits of packaging.

In our business, we come across many individuals that ask us the question, “Why use packaging in the first place?” There is great concern about packaging adding significantly to the overflowing landfills. And it’s true. According to the US Environmental Protection Agency (EPA) 2008 report, “Containers and packaging made up the largest portion of municipal solid waste generated in 2007: 31 percent or 78 million tons.”

Fresh produce packaged in Earthcycle

But let’s face it, when it comes to food packaging in particular, our convenience-driven and health conscious society with a growing affinity for portion-sized pre-packaged food cannot and maybe should not do without it. In particular with the recent panic surrounding the H1N1 virus, you want to know your food is wrapped safely from any possible contaminants and from pathogens in the air when it’s displayed in grocery stores.

And let’s not forget, packaging will protect from germs that can transfer from shoppers picking over the produce. Then there’s the damage to consider. In bulk displays, retailers are throwing away anywhere from 15 to 18 percent of produce due to it being picked over and damaged. With packaging, there is only five to eight percent waste at most.

So packaging is not only helpful for our health, but it also assists the retailer with maintenance of product integrity at store shelves and decreases the amount of fresh produce waste that will otherwise end up in landfills. James McWilliams discusses these issues in more detail in his recent New York Times article, “How About Them (Wrapped) Apples?” It is a worthwhile read.

This still leaves us with the overflowing landfills and waterways contaminated by packaging. But there are many packaging alternatives now available, including PLA and agricultural fiber options which are cost competitive with traditional plastics such as PET. Earthcycle is one of them. When we first conceptualized Earthcycle Packaging in 2004, we took the various issues discussed above among many more into consideration and believe that the benefits of packaging in the produce industry far outweigh the negatives.

In this day and age, we do not necessarily have to do without. We have the knowledge and understanding to leverage the design brilliance of nature to come up with the type of products that we have come to depend on without creating more waste or environmental harm in the meantime.

Our Earthcycle packaging, for example, follows the cycle of nature. Our product life cycle starts with a natural renewable resource, palm fiber, from which we mould certified home compostable packaging. Once the packaging has done its job protecting our food, it can be thrown into any compost and will break down within 90 days, returning to the earth as humus and creating valuable nutrients for the soil.

Bioplastics  are a form of plastic that come from renewable sources, such as corn, vegetable oil or corn starch, for example. They differ from the standard plastics, made from petroleum, that we have come to depend on in society over the past several decades. For example, many clear plastic containers today are made from PLA or polylactic acid – a resin produced from corn. NatureWorks  in the USA is the world’s largest producer of PLA. Their containers are compostable in industrial composting facilities only. PLA is also used in cups and containers as an impermeable liner.

Scanning the Internet, there has been quite the debate over the past few years on whether or not corn plastic actually makes us better off than our conventional petroleum based PET. So here is a condensed list derived from the more prominent sources* that summarizes some of the key advantages and disadvantages of corn plastic:

Advantages of PLA

  1. Derived from corn which is a renewable resource
  2. PLA products are compostable in industrial composting facilities
  3. PLA is cost competitive with regular petroleum-based resins such as PET and most likely cost advantaged in the future given rising petroleum prices
  4. Producing PLA uses 65% less energy than producing conventional plastics
  5. Producing PLA creates 68% fewer greenhouse gases than producing conventional plastics
  6. PLA contains no toxins
  7. From a safety perspective it will not blow up like oil might

PLA pellets

Drawbacks/Criticism of PLA
  1. PLA is only compostable in industrial composting facilities – access is limited as only few sites in the USA exist (113+)
  2. PLA in large amounts may interfere with conventional composting because the resulting polymer will make the compost wetter and more acidic
  3. Consumers will dump PLA in with their regular PET recycling which can contaminate the PET recycling stream if it happens in large quantities
  4. Material Recovery Facilities (MRFs) have to pay to sort out PLA and pay again to dispose of it
  5. Because of the lack of infrastructure, the majority of PLA packaging is likely to still end up in landfills
  6. Most of the corn used to produce PLA is genetically modified
  7. Some individuals raise morality concerns in using food for packaging if so many people in the world are starving

In addition to PLA, there are a number of other renewable packaging alternatives hitting the markets, most notably, agricultural fiber products produced using natural fibers such as bagasse, bamboo, bulrush, and palm fiber. They differ mainly in that they can be composted at home, not requiring an industrial composting facility.  While they have many advantages, agricultural fiber based products are not necessarily direct substitutes to PLA. For example, they cannot be used for high moisture applications, such as cups, without partnering with PLA or other such product to offer a barrier coating.
