Sewage Treatment - Micromidas has Green Technology for a Messy Problem

As I noted in an earlier post, the matter of figuring out the best way to dispose of human waste has been haunting mankind since the beginnings of civilization.   Current treatment of raw sewage results in large quantities of sludge which is not good fertilizer and is laden with toxic materials. Disposing of sludge is a huge problem for waste treatment plants.   Enter Micromidas, a finalist at the Clean Tech Open.  They have an idea - and it sounds like it's loadSludgeSludgeed with win!

Why It's Keen:  

Using Microbes, they are able to convert the CO2 in the sludge into polyhydroxylalkanoate (PHA) flakes which then can be turned into bio-plastics.  Bio-plastics can be used for plastic containers and function similar to synthetic plastics.   Finally, by capturing carbon that would normally be released into the atmosphere the process should result in carbon credits, mostly likely for the municipality who runs the sewage treatment plant.  If this turns out to be true, it could be a key element in turning this technology into a reality as it will make it easier to be economically as well as environmentally justified.  

Why It's Green:

Animal Welfare Essential to Sustainable Development

On October 8, the World Society for the Protection of Animals (WSPA) presented a talk on the need to include animal welfare as an essential element in the sustainable development agenda.  The speaker of the talks is Michael Baker, WSPA's Director General.  The most striking thing that I found in the video is the lack of an audience.  Did anyone else notice that the room was essentially bare?  Does this speak to the animal rights movements support or just an exhaustion with climate change related topics in the media?... read more

Clean Tech applications: Ride share and carpooling

Remember how hitchhiking was an accepted mode of transit in America years ago? Well, now we have ride sharing. With approximately ¾ of commuters driving alone to work in the U.S. every weekday, alternative transportation modes bring many benefits.

Ride sharing is a simple way to save money, reduce one’s carbon footprint, provide opportunities to network and expand one’s contacts, reduce driving stress, as well as pleasant. Find friends, neighbors, and co-workers who are traveling the same way you are – for school, work, events or leisure – and share a ride.

There are several variations of sharing transit: carpooling, where pool members use their own private cars. Ride-share also refers to members jointly share the costs of a rented car; or sharing a ride in a hired vehicle with a hired driver, like a shared taxi, shuttle, vanpools, etc.... read more

How to move the public on climate action?

Many Americans believe climate change is an impending environmental threat that faces us in the next millennium, however, although global warming is considered the biggest threat, most people are not committed to making the choices and lifestyle changes that are required. 

While, global temperatures are rising, weather conditions change across the world, the Arctic ice cap is melting, scientists and environmentalists are presenting urgent warnings about climate change, politicians, business leaders and financial ventures incentivize, stimulate and invest in new Green technologies - people acknowledge the threat, but are still not taking personal actions to reduce the problem.

Today, a number of scientists acknowledge that some climate change may not be reversible.

Interview with Dr. David Lee, CEO of BioSolar - Renewable Plastics In Solar

Last week I had the opportunity to interview Dr. David Lee, Chief Executive Officer of BioSolar.  Dr. David Lee founded BioSolar in 2006 in an effort to make renewable materials for the packaging of photovoltaic cell converters.  Dr. Lee holds a Ph.D. in Electrical Engineering from Purdue University, a Master of Science in Electrical Engineering from the University of Michigan - Ann Arbor, and a Bachelor of Science in Electrical Engineering from the University of Texas at Austin.  It was a wonderful interview that provides insight into the company's mission, research and commercialization. 

I am going to start off by asking about your previous work experience.  You have worked for Applied Reasoning Systems Corporation and RF-Link Technology, Inc.  Both of those did not have anything to do with solar industry.  One was an Internet software company and the other a wireless technology corporation.  What made you take the leap into solar technology?

Actually, it is not a long story.  I majored in electrical engineering for my bachelors, masters & Ph.D.  One of my hobby projects was solar technology, especially the material science side of it.  Even though I ended up getting a Ph.D in communications science, my interest level has always been there.  

My first job was at a defense contractor where we designed satellite communication systems for the U.S. government.  I was a systems engineer.  The job of the systems engineer is to oversee the entire project.  That involves many different disciplines, not just communication systems disciplines but also different sub-systems that constitute the entire project.  My background was much more broad than what most people think.

You mentioned my experience in RF Technology.  It was a wireless technology company that dealt with both terrestrial and wireless communication devices.  Applied Reasoning was a software development company.  It also had a lot of space technology related implications in its application. 

I did not simply start the idea of a solar company all of a sudden.  I always had the dream of making solar technology something we can all take advantage of.

Green Landscaping Solutions For The Bay Area: CK Management Systems

For years now there existed a disconnect between the nature present inpeople's front yards with the synthetic and wasteful gardening used tokeep these areas green. For example, most fertilizers or growthadditives used in suburban, urban and rural settings are synthetic withhigh amounts of salt, nitrogen & phosphate. These toxic growthadditives create an immediate but very short growth in the plantsapplied to, but stunt the roots of the plants. This prevents theseplants from fully absorbing underground saturation and maintaining... read more

Neighborhood Fruit: Creating a "Community of Trust"

Neighborhhod Fruit Logo

The best green companies take a holistic approach to providing a community with its needs – an approach that address not only the environmental aspects in its business practices, but also actively involves the people in the community it serves. Throw in a financially sustainable model to keep the practices going, and you have business which includes people, planet, and profit in its bottom line.

One business which takes this “integrated bottom line” approach just came on the scene in May. Neighborhood Fruit emerged out of a final class project dreamed up (literally) by Kaytea Petro, then an MBA student at Presidio School of Management in San Francisco. After graduation, Petro and fellow classmate Oriana Sarac teamed up to build a site designed to “make use of the abundant fruit growing in our urban neighborhoods.” The site serves several functions: utilizing an abundance and diversity of local fruits, vegetables, and herbs (contrary to their name, they’re not fruit-centric); creating community connectivity; and reducing the amount of excessive water, fuel, and other resources which would otherwise have been required for the production and transportation of the same amount produce grown commercially in orchards and fields far away from our homes.... read more
