Zero Waste: Eccentric Hobby or Wave of the Future?


As I learned from living there during four years of college, California is a land of extremes.  The all-time U. S. record high temperature of 134 degrees Fahrenheit was recorded in Death Valley, which has the lowest land elevation in the U. S. too, and this principle extends to human behavior as well.  A recent post on the San Jose Mercury-News website tells the story of Anne-Marie Bonneau, whose teenage daughter read about floating islands of plastic trash in the oceans back in 2011.  Just as monks and nuns of old took vows of poverty, chastity, and obedience, Ms. Bonneau took a vow then and there to never buy another piece of plastic again. 

She’s still living up to her vow, and has extended the notion of cutting back waste to the extent that she has to take out the garbage only once a year, in a shopping bag (paper, not plastic, no doubt).  Not everybody would care to go to the extremes that Ms. Bonneau does.  She collects glass jars to store liquids in, buys shampoo in bulk, and makes her own deodorant and granola.  Her daughter Charlotte, while she is still on board with the zero-waste idea most of the time, has committed acts of rebellion from time to time, such as buying a plastic water bottle.  And she threatened to leave home if her mother switched from toilet paper to rewashable cloths, so they still buy toilet paper (but not in plastic bags).  Bonneau, whose day job as an editor must leave her with enough energy to run a part-time two-person recycling company and manufacturing firm, admits she is “hard-core.”  But she evidently feels strongly enough about how the planet’s oceans are getting trashed with an estimated 19 billion pounds of plastic every year that it gives her the energy and motivation to do what she and her daughter do along these lines. 

Ms. Bonneau is not alone, though few go almost to the limit of zero waste as she has. Recycling in some form happens in most large cities in the U. S. and smaller towns are catching up too.  While we sometimes think of it as a new idea, nature has been recycling since the beginning of life, at least.  Organic material comes from the soil into plants, animals eat the plants, and both during and after the animal’s life, the material returns to the soil.  And there is a line of thought out there that seems to say if we would only get rid of all this Industrial Revolution stuff—fossil fuels and plastic and climate-change-causing combustion—and live like people did prior to, say, 1500 A. D., then we’d have a sustainable economy and ecosystem. 

The trouble is, there would be a lot fewer of us to enjoy it.  Before Europeans came along, the North American continent supported fewer than a million residents.  And if you think making your own deodorant is hard, try catching enough fish and wildlife every day to live on.  Any archaeologist knows that the most informative thing you can discover about an ancient settlement is its trash heap.  And from trash heaps, we know that even ancient civilizations were pretty wasteful and generated a fair amount of trash.  I don’t know of any numerical comparisons, but my point is that just getting rid of plastic packaging would not automatically solve all our trash problems, though it would help.

Under the present circumstances that prevail in most parts of the U. S., there is not much motivation for those who do not have the exquisitely sensitive global-political conscience of Ms. Bonneau to reduce one’s weekly trash production.  To speak personally, my city provides us with three (plastic, sorry) trash barrels, each capable of holding a couple of cubic yards of stuff.  One is for green waste that presumably goes to a compost pile somewhere, another is for specific types of recyclable materials (plastic, glass, aluminum), and the third is for any general trash that can’t go into the first two.  For what it’s worth, our contribution to the recycle bin is usually larger than our contribution to the trash bin, and I’ve often felt kind of silly tossing one small bag of trash into that great big bin each week.  I suppose I should have felt guilty for using it that much.

Here’s an idea which probably won’t be very popular, because it would cost people money.  But I’ll float it anyway.  The technology exists for trash-pickup trucks to register the net weight of everybody’s trash as they stop and lift it with those big fork kind of things into the truck.  What if you were charged by the pound for your trash?  And what if it was a pretty steep charge after a first flat rate?  That would get a lot of attention from people who currently don’t give a flip about how much stuff they throw out.  It has the advantage of letting folks who value plastic above money to keep doing what they’re doing, but it would re-train the rest of us to buy stuff that leaves less trash behind. 

A brief Internet search turned up a single instance where this idea has been tried:  in 1993, in California, naturally.  A trash-pickup firm serving Thousand Oaks and Ventura experimented with a prototype system from a North Carolina firm.  But on the day a reporter came to witness the first public trial, the system got weights wrong by three to six pounds and missed one trash can entirely.  For whatever reason, even though the idea has been around for more than twenty years, it hasn’t caught on.

So that means if you want to reduce your contribution to the global trash pile, you are more or less on your own.  Ms. Bonneau’s example is out there for anyone who wishes to try it, but outside of the famously ecologically-minded culture of the Bay Area, you may be regarded as a little eccentric.  For most of us, making small changes in what and how we buy things will help some.  For example, after I read Jen Hatmaker’s 7 Experiment:  Staging Your Own Mutiny Against Excess, I started reusing the plastic bag I put my lunch sandwich in, keeping it for a week instead of throwing it away every day and getting a new one.  That’s about as small a change as you can make and still be able to say you’ve done something, but it’s better than nothing, I suppose.

Pope Francis' Vision for a New Ecology


When the spiritual leader of the largest division of the Christian faith says something about climate change and the problems of technological progress, engineers of all faiths and no faith should take notice.  Last Thursday, Pope Francis released his latest encyclical, Laudato Si', known in English as "On the Care of Our Common Home."

Contrary to some reports, in the encyclical Pope Francis doesn't come out in favor of Marxism, though he does say that international efforts to control greenhouse-gas emissions have failed and that something stronger is needed.  And he doesn't say you can't be a good Catholic if you use air conditioning, though he does use air conditioning as an example of a "harmful habit of consumption."  What he does is to lay out a vision for how humanity can turn around from a lot of wrong paths and get back on the right path, which is all a good sermon does anyway. 

What are the wrong paths?  While most environmental activists concentrate on actions, statistics, and policies, Pope Francis goes to the heart of the problem:  sin.  God's world as originally created was good.  But when man decided he knew better than God, things started to go wrong.  There's nothing new about sin, but what is new in the last couple of hundred years is mankind's ability to transform the environment through technology.  A few hundred thousand cave men armed with spears couldn't make much difference to the global environment no matter what they did.  But seven billion people using massive amounts of organized technological power and treating the earth simply as a raw-material resource can cause tremendous harm, both to the environment and many of the poorest people who try to live in it.

Pope Francis's roots are in the Global South, and his concern for the billions of the poorest people around the world is evident on every page of Laudato Si'.  What if you are the father of a family on the coast of Africa, trying to feed yourself by fishing, and some pollution kills the fish and the ocean rises so much that your land is flooded out?  What if you then move to the city and try to commute to a low-paying job three hours a day on filthy, crowded buses while breathing soot-filled air that gives you a lung disease that makes you so sick that you lose your job?  While the physical environment and the marvelous biodiversity of plant and animal life on our planet come in for mention, Pope Francis's fundamental concern is for people, each one of whom is a child of God and deserving of respect, attention, and love.  But when giant economic and technological systems conspire to deprive millions of their culture, their land, and their livelihood, these folks can no longer receive what they have a fundamental right to as human beings.

What are the answers?  Pope Francis wisely refrains from making explicit scientific pronouncements or calling for specific laws or policies.  Instead, he spends much of his time asking for dialogue between governments and citizens, between the privileged and the empoverished, and between scientists and religious believers.  He hopes—and there are many places where he expresses hope—that men and women of good will, emboldened by a vision of humanity as one family sharing one planetary household, can change their ways for the better.  These changes include everything from family efforts to save energy and recycle products up to stronger international agreements that could make a real difference in the rate at which fossil fuels are being used. 

At the beginning and again at the end of the encyclical, he mentions the saint whose name he bears, St. Francis of Assisi.  St. Francis was a revolutionary figure in the tradition of Martin Luther King, Gandhi, and Jesus himself.  He lived in utter poverty, but with such love for all creatures, both animal and human, that he collected followers who sought to carry out his vision of Christian love in a unique way that was both humble and vastly effective. 

Much of what Pope Francis criticizes is the byproduct of pride, which theologians know is the root sin, the sin that enables all the others.  If we think we have all the answers and that the material world is simply waiting for us to bend it to our whims, we are in fact enslaved to the sin of pride, and all the problems mentioned in the encyclical can be traced in one way or another back to that attitude. 

On the other hand, if we look on the world as a wonderful gift, packed with hidden prizes and meanings to be treasured, not just exploited, we will tread more gently.  We will think before we act, or buy, or sell, or design.  We will bear in mind not only our own family, and our friends and social groups, but also others who might be affected by what we do, or purchase, or waste.  And we will change our ways accordingly.  Among other things, that is what engineering ethics is all about.

With Laudato Si', Pope Francis has not gone off the deep end politically or theologically. The encyclical emerges from a deep consideration of the entire Christian tradition and its meaning for how spiritual beings can best live in a material world, being themselves material as well.  While not many previous popes have made ecological concerns a focus of their ministries, I think Pope Francis has chosen the right time to do so.  And anyone who has any dealings with modern technology, whether as an engineer or an ordinary citizen who simply lives in the modern world, needs to give serious consideration to what he is saying.
