One Cup Coffee at a Time – The Sustainable Way

Aero Press

The AeroPress

My wife Gail and I are self proclaimed coffee snobs. We like our coffee strong, robust and fresh. We have been buying whole bean coffee and  grinding our own beans since 1978, and have had every kind of coffee brewer, espresso maker and French Press you can imagine. My wife and I are now empty nesters. Our son Joshua is married with a family of his own. Our daughter Michelle is away at college. We no longer need to make a full pot of coffee every morning. But, we are strong believers in sustainability and recycling so we will never ever buy one of the fancy expensive single cup coffee makers that are so popular.

These one cup coffee machine, such as the Keurig and Tassimo, seem to have become ubiquitous. I see their little “k-cups” and coffee pods everywhere. Although expensive, many people have opted for the convenience  offered by these single serving coffee systems. According to the Los Angeles Times, in the 12 months ending in November, nearly 46% of the dollars going toward the purchase of coffee or espresso makers went to single-serve machines. The L.A. times story reports that according to Keurig 13% of all US offices has one of their machines.

The problem with this is that single servings of anything, by definition, have more packaging and create more waste than buying the same product in bulk. In this case, the environmental impact is complicated by the difficulty in recycling the single serving k-cups and pods. Tim Wall at Discovery News points out that the k-cups are made of a plastic shell, lined with a paper filter and topped with aluminum. Individually, the components are recyclable, but put together they can only be trashed. What’s more, the compostable coffee grounds are trapped inside.

So how to make a single or double cup of really good coffee while staying true to our core values? The answer turned out to be a $30 little plastic coffee maker called the AeroPress. I had kept coming across references to it in different blogs but couldn’t find it in any local store. The reviews were simply amazing. As explained by Mike Crimmins in his Daily Shot of Coffee Blog, the Aeropress came from inventor Alan Adler, who is best known for his Aerobie flying ring and similar toys. He took a scientific approach to making coffee and came up with the Aeropress.

The Aeropress is a simple machine. According to Gizmag the AeroPress delivers the smoothest, richest, purest and fastest cup of coffee (under 30 seconds) you’re likely to find.  The AeroPress can make up to four cups of great coffee at a time, much faster than my espresso machine or a single cup system. I have to agree and best of all, the only consumables used are the coffee grounds and the small paper filter, both of which are compostable.

 


By-products that reduce Pollution?

Monday, October 3rd, 2011

New technology is one of the biggest catalysts for our economy, always has been and always will be. Right now, scientists in China have been introducing cleaner and greener tech, which creates fewer by-products while saving money. These new technologies are coming at the right time, when costs for fuel are higher than ever and companies are looking for ways to reduce costs. Taking all of this into consideration, these scientists have been working on a new composite material made from wood and plastic that will be better for the environment, create no harmful by-products, be stronger than traditional recycled plastic and (supposedly) cheaper! What is there to lose? Many industries, such as the automobile and textile, have already started adopting this tech in China. Soon it will be ready for the world. To break it down further, I have created five little sections below that explain the Wood Plastic Composite (WPC) and how it will change these industries and why it is better and more desirable than just recycled plastic on it’s own.

Humans are wasteful; it’s in our nature. Luckily, we also are smart enough to develop new technologies like WPC. Now the smaller branches of trees, saw dust and other waste wood pieces, which otherwise end up in a landfill, can easily be turned into a composite material made by binding the wood with plastic polymers.

What does this mean for you? Maybe not much right now, unless you are in the market for a new deck (which the material is already being used for) but what it will lead to, is new a new material made from the waste. Reusing wood waste is inherently eco-friendly. However, the most ecologically minded aspect of this new tech is the end product itself. The plant fiber-based composite will reduce the cost of the production of wood while simultaneously reducing the industries negative impact on the environment.

Who came up with this great idea? Scientists from the Institute of Wood Science and Technology (IWST) developed the technology in China.  Many people are already importing this technology from China. When asked about the possibilities of this new material, Dr. Ajay Karmarkar, a scientist working on the project with IWST said,

“The experiment was being conducted for the past 10 years and finally we came to a conclusion that the by-products can be used by automobile, packaging, and textile industries. Plastic hangers and buckets, wooden door frames and windows can be replaced by this ecofriendly composite material.”

What are the advantages? Once plastic is recycled, its usage becomes less because it loses stiffness.  WPC will increase stiffness by 70% and at the same time, be 50% less expensive than it’s traditional wood counterpart. Plus, during the manufacturing process, the only by-products that are created are 100% environmentally friendly.

How do they make WPC? The process takes fibrous material from wood, bamboo and jute, mixes it with the plastic polymers and run it through the twin-screw extruder. This machine melts, mixes and pumps the product. This by-product is then put into a pelletizer, which chops it up into tiny granules. To get the desired size and shape the granules are put into the injection-moulding machine next. Finally the WPC is put through tensile stiffness and compression strength testing.

Since being debuted WPC has won over many industries, ones which welcome the idea of new technology. The benefits for the environment and production are numerous and the overall cost is lower.  Soon we hope to see WPC in more products all over the world. Maybe, it will even show up soon in our Industrial Packaging.

Hazardous Waste Violations – Metal Finishing Company Pays $38,250 to EPA

Friday, February 18th, 2011

Saco, ME

Southern Maine Specialties, when asked if the waste generated on-site was hazardous, they had no idea! For this reason and many others they were charged with violating state and federal hazardous waste laws.
Where they went wrong:

• Storing containers of HazWaste next to incompatible material(s).
• Storing two 55-gallon drums of sodium hydroxide sludge together, in excess of the 55-gallon limit for HazWaste accumulation.
• Failed to provide required HazWaste management training for employees
• Storing HazWaste in a tank not designed for that purpose.

The complaint stemmed from an EPA inspection of the facility in January 2010.
EPA inspections happen all the time, are you and/or your company prepared? Contact Maxi with any questions toll free 1-800-727-MAXI (6294) or email Rick our HazWaste expert here: rick@maxicontainer.com

It is noted in the report that Southern Maine acted quickly in rectifying all of the complaints against them. But I have to ask is being ignorant of state and federal HazWaste laws really worth a $38,250 claim against your company?
