US Company Transforms Algae into Bioplastic: Could Slash Petroleum Use by 50%

California-based company Cereplast has revealed that it is developing breakthrough technology to transform algae into bioplastics, and predicts that it could replace 50% or more of the petroleum content used in traditional plastic resins.

Cereplast already makes plastic from renewable material such as corn starch, tapioca, wheat and potatoes, but is keen to trumpet the advantages of the new approach.

According to Frederic Scheer, Founder, Chairman and CEO of Cereplast, “Algae-based resins represent an outstanding opportunity for companies across the plastic supply chain to become more environmentally sustainable and reduce the industry’s reliance on oil.”

BPA: Low Doses Are Poisonous, Too

In the wake of the Sigg/bisphenol-A controversy, a top researcher and CEO of Environmental Health Sciences fills us in on the news: endocrine disruptors such as BPA and phthalates are indeed toxic at low-level doses, too. And they’re toxic in entirely different ways than at the traditional high-dose testing indicates.

The way the tests work today is we think that by testing at high doses we’re gonna see everything. So that once we get to a dose that’s intermediate and we don’t see anything, we’re golden.

But the science is telling us that at really low doses as contaminants mimic hormones. They can have effects that are totally unpredictable by what happens at high doses.

Pete Myers spoke to Living on Earth about the consequences of current testing.

Hot Water: How SIGG Lost My Trust (And Kind of Broke My Heart)

I waited to write this post until after I had the opportunity to speak with SIGG CEO Steve Wasik. I am still disappointed.

Over this last week we have learned that SIGG bottles manufactured before August 2008 (not 2009, as I mistakenly mentioned earlier) contained Bisphenol-A (BPA) in their liners. BPA is a chemical used in the manufacture of polycarbonate plastics and epoxy resins and is part of a group of molecules known as endocrine disruptors.

Endocrine disruptors are defined by the National Institute of Health as

naturally occurring compounds or man-made chemicals that may interfere with the production or activity of hormones of the endocrine system leading to adverse health effects. Many of these chemicals have been linked with developmental, reproductive, neural, immune, and other problems in wildlife and laboratory animals. Some scientists think these chemicals also are adversely affecting human health in similar ways resulting in declined fertility and increased incidences or progression of some diseases including endometriosis and cancers.

It produces ornate light fittings, home décor and jewelry crafted from, among other things, recycled glass bottles, yoghurt containers, plastic, dog food cans, mosaic, bits of mirror, toys, charms and copper wire.

Journey into the “Great Pacific Ocean Garbage Patch” — Scientific Findings


The “Great Pacific Ocean Garbage Patch” lies about 1,000 miles from the coast of California. It is in the North Pacific Ocean Gyre, which is one of the oldest and most diverse ecosystems in the world. The garbage patch has gotten a lot of media attention in the last year. However, due to the fact that one must get on a boat and go all the way out to the patch to study it, there hadn’t been any in-depth scientific analysis of the patch,… until now.

The Scripps Environmental Accumulation of Plastic Expedition (SEAPLEX) went on an in-depth search of the “Great Pacific Ocean Garbage Patch” this month. Their findings were varied.

Inflatable Bag Monsters Arise from New York Subways

Innovative artist Joshua Allen Harris has created a menagerie of inflatable monsters that are ephemeral, whimsical and utterly delightful. All of his different creatures are made from old plastic bags, and magically come to life from the air generated by New York city subway vent exhaust.

Steven Psyllos interviewed Harris recently for New York magazine to discuss his inspiration, artistic process,  and to unveil a new animated plastic bag beast; the video was shot by Jonah Green.

“BPA-Free” Bottles–Guess What?–Leach BPA

A new Health Canada study found that bottles marketed as “BPA-free” actually leach the hormone-disrupting chemical into liquids.

The study says that these bottles contain “trace amounts”, but some sources cite an internal memo, which says that two brands contain “high doses”.

For their part, bottle manufacturers claim that the study must have been performed wrong.

The Latest Medical Innovation: Recycled TVs

Researchers at the University of York have recently come up with a method of recycling that seems like it fell from the pages of a science fiction novel. They want to turn discarded television screens into components for biomedicine.

Crafty Reuse: Shower Curtain Liners

Last week, commenter Robyn asked about crafty ideas for reusing an old shower curtain liner. What a great question! It turns out there are several ways to reuse that old shower curtain liner.

Re-nest suggests using tarps to kill weeds in your yard. Why not use an old liner place of the tarp? Just weigh it down with bricks over the problem area on a sunny day. The plastic liner will trap the heat from the sun. There’s a good chance you’ll kill any other plants underneath there, so this is probably best if you’re clearing an area to plant a garden bed.

But that’s just the beginning! Check out these other crafty ideas for that old plastic shower curtain or liner:
