The Recycling Symbol does NOT mean "curbside recyclable".

We've all seen the famous recycling symbol on products, like these:

The Weird "Recycling Symbol" Surprise

The "Recycling" symbol you see on packaging and products are NOT designed to have anything to do with curbside recycling. Instead, the symbol is merely an indicator of what kind of material it is made out of.

Industry plasters this symbol on many products that are to be thrown in the trash. Industry over-applies this symbol as a "greenwashing" strategy, tricking consumers into believing that a product is recyclable when in reality it is not. And Consumers are tricked: people WANT stuff to be recyclable, and so they throw it into the recycle bin. Then the bad item gets blended into a bunch of other otherwise good stuff, and diminishes the entire lot.

So what is recyclable? The answer is: read your local recycling rules, and be a pessimist. If in doubt, it is better to throw it into the trash than to ruin an entire lot of recyclables.

Before you worry about not recycling enough, remember that some trash IS processed for recyclables. Metals, particularly aluminum and iron-based metals, are easily picked out of trash, and in some places decades-old landfills are mined to get at the metals, using the principle of "its better to look for stuff in a landfill than to spend the money to scrape off the top of a mountain". So it isn't all bad.

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

The Trick to Properly Fixing the Rubber Feet of a MacBook Pro

A black rubber foot of my trusty old MacBook Pro finally broke off, and I didn't like how it made the laptop wobbly. A fix was needed, and quick! First I bought some replacement feet, the kind that just stick on. These feet are nice because there is no need open up the machine to fix a broken foot. They're very inexpensive, and the ones I bought have adhesive tape already applied - just peal and stick. I bought feet like the ones found here. I have read many complaints about how the adhesive doesn't stick, but I think that's because people don't know the two tricks required to get the new feet to stick properly. New Feet to replace a lost Foot Important Trick 1: Make sure to remove all remnants of the old foot - including the pieces in the hole. My factory-installed foot was attached both mechanically and with adhesive, but when the old foot sheared off, some pieces of the old foot remained in the hole. Those plastic bits would h...

Repairing a MagSafe Charger's Cord

Here is how to repair the cord of Apple MacSafe power adapters. There are three common failure modes of a magsafe wire: The base of the cord becomes frayed where the wire enters the power brick. This is usually caused by repeatedly wrapping the cord far too tightly around the brick's "ears". The head of the magsafe connector becomes frayed. This is usually caused by repeatedly removing the magsafe magnet by yanking on the cord. Chewed up cord. This is where a pet or other pinching device weakens the cord.

My Porsche's remote key was getting weaker and weaker, until one day it stopped operating altogether. Keyless remote without the remoteness. Not so good.

At the same time I use my fingers to start to pull the two halves apart. From th...

MacBook: burnt out magsafe connector repair

My MacBook (A1342 model from 2009-2010) stopped working, thanks to a cheap knockoff magsafe charger. The magsafe connector looked burnt with heat-distorted melted plastic and some black carbon surfaces. Plugging in the charger resulted in no lights and no action. My MacBook was dead. First I tried to clean up the connector with some Q-Tips, tooth picks and solvent, but that did little, as seen in this "after" picture (below). The heat generated by the aftermarket charger permanently deformed and distorted the MacBook's magsafe connector. Clearly the damage was significant. Burnt Magsafe Connector - Replacement Required! Looking at iFixIt , I determined that it would not be difficult to replace only the magsafe connector with the right tools.
