Sewage Sludge: Everything You Wanted to Know but Were Afraid to Ask

I've been looking into sludge.  It's not a pretty picture.   I am working on a profile of Micromidas, a Clean Tech Open finalist that aims to make the business of treating raw sewage a bit less messy by extracting carbon from sludge and turning it into biodegradable plastics.  But more on that later this week.   Sewage, sludge, human waste  ... it's a dirty problem and one of the major by-products of human civilization.   I came across this fascinating writeup -  Civilization & Sludge: Notes on the History of the Management of Human Excreta. 

I remember mulling over this problem as a child (kids are fascinated with poop) .... where does it all go?  This article traces the history of mankind's battle with with their by-products.  It's been ugly and we have just been moving the problem from one place to another.   Whether it has been cesspools polluting private property, open city sewers causing mass outbreaks of cholera, typhoid when the sewage was dumped into nearby rivers or disgusting beaches when we pursued dumping sewage into the ocean with a "solution by dilution" approach. ... read more

Waste Heat - Alphabet Energy Tackles a Hot Problem

Have you ever opened and worked on your car engine while it is still hot?  Ouch - the average temperature of a running engine is 170-200 degrees farenheit. One thing I have never considered - cars (and basically all things that run hot) are creating heat waste.   Wasted heat  is created as a by-product of the conversion process of fuel into usable energy. 


One of the ideas that really caught my attention at the Cleantech Open was presented by finalist Alphabet Energy Inc.  They are working on technology that will recapture waste heat.   According to Alphabet Energy, the average power plant is only 30% efficient and the same efficiency number has been cited for automobiles. ... read more

Clean Tech Open Gala Awards

I was fortunate enough to attend the CleanTech Open this week in San Francisco.   The  CleanTech Open is a business plan competition in the Green sector and they provide mentoring and  significant funding (and media and VC attention) to Green start-ups.   These were their Academy Awards at the beautiful Masonic.   I particularly enjoyed the variety, creativity and potential of the finalists  and imagine  there are many great ideas that didn't make it to the finals.  This gave me a lot to write about and even one product to lust about.  I want one of these 3 wheeled vehicles which will get 100 mpg and bends into a turn like a motorcycle (from Green Lite Motors).... read more

Berkeley’s Solar Plan to Serve as a Model for Biden’s Plan

Solar PanelsSolar PanelsThe dilemma for the environmentally conscious consumer often comes down to dollars and cents.    That problem is particularly acute when it comes to solar systems where the investment in a solar panel system can cost on average of more than $20,000.   Yes, there is monthly savings but the payback period can be as long as 10 years.   That’s a tough pill to swallow, even for the most enthusiastic, green-eyed Prius owner, not to mention the average consumer who is just becoming aware of the global warming and energy crisis.

Enter the plan trialed in Berkeley, CA and followed up in several U.S. cities.  Homeowners pay zero upfront dollars.  The plan is financed by the government and paid off with a monthly tax surcharge over twenty years.  The energy savings offset the monthly tax bill.  This makes the upgrade a virtual freebie and may even improve the market value of the home.

Where Do Our Recyclable Electronics Go? The Electronic Wasteland!

Okay - I admit it - I am just 1 year into my Blackberry contract and I am already lusting for a new one.   My Bad!  What about the environmental impact for tossing away my cell phone as 100 million people in the U.S. do each year?

No worries - I'll recycle and feel totally guilt free as I stroll into my neighborhood Sprint store and toss down my plastic.   My Good?  My Bad? It all depends.

Recycling is a great mechanism to make ourselves feel good about all the waste we produce. But what happens to the electronics we recycle?  According to a 60 Minutes expose that was rerun this past Sunday, it is often not what you think.
