Trillium ovatum — Western Trillium
Earth Day was started in 1970 by US Senator Gaylord Nelson. Celebrated on April 22nd, Earth Day reminds us that we share responsibility for the health (salute) of our beautiful planet (pianeta).
There are a few thoughts I have been meaning to share with you for some time and Earth Day (or thereabouts) sounds like the appropriate time. In recent years, I have become particularly interested in food waste (spreco alimentare) and food scrap recycling.
Food waste includes uneaten food and food preparation scraps from residences or households, commercial establishments like restaurants, grocery stores, cafeterias and industrial sources. (source: Environmental Protection Agency)
The amount of food that goes to waste in the US every year is staggering:
The US generates more than 34 million tons of food waste each year. Paper is the only material category where we generate more waste, but we also recycle more. Food waste is more than 14 percent of the total municipal solid waste [MSW] stream. Less than three percent of the 34 million tons of food waste generated in 2009 was recovered and recycled. The rest —33 million tons— was thrown away. Food waste now represents the single largest component of MSW reaching landfills and incinerators. (source: EPA)
Not only does this wasted valuable resource have huge economic impacts, it also has huge and immediate environmental impacts. When food is disposed in a landfill it quickly rots and becomes a significant source of methane — a potent greenhouse gas with 21 times the global warming potential of carbon dioxide. Landfills are a major source of human-related methane in the United States, accounting for more than 20 percent of all methane emissions. (source: EPA)
After having stated the problem, let’s talk about ways to address it. Another page on the EPA’s website shows the food waste recovery hierarchy and yet another one suggests ways for households to address the food waste problem. I really like the subtitle of this last page: Think – Reduce, Reuse, Recycle (compost). Thinking about what we are doing allows us to become aware of where waste occurs. Then, we can implement measures aimed at minimizing waste.
For example, food waste can occur when we purchase more food than we consume, in particular perishable items like fresh vegetables. We can do a lot to help our planet by paying special attention to our shopping cart or basket and to all the drawers of our fridge plus those nooks and crannies where food has a tendency to hide and condemn itself to oblivion. Precious resources went into the production of that food: when we throw it, those resources become wasted. The way to minimize the environmental impact of food that, for various reasons, must be discarded is recycling, i.e., composting.
If you are interested in learning more, I have written two articles on the subject of food waste and of food scrap recycling: one is here (on page 45) and one is here (pdf). Wasted Food is a blog totally dedicated to this important topic. This recent post provides cogent reasons for why food waste matters.
Readers in the UK may have heard about plans to review current food labeling practices to clarify the labels and reduce waste. Here is a commentary on the announcement.
Unavoidable food waste can be turned not only into natural fertilizer (compost), but also into energy: this happens in facilities called anaerobic digesters, one of which is in Oakland, CA.
One more thing: take a look at the site Love Food Hate Waste.

Food for thought…pun intended. Thanks for all the links, this is something that is always in my mind. You wouldn’t believe the amount of stuff that gets thrown away in restaurants and caterers, it is disgusting and depressing. One time I was trying to donate pastry unsold items to a bettered woman’s center and the owner got mad at me for not asking his approval and he never wanted to deal with the problem again. It is something nobody wants to think about.
I will check those links out.
Buon 25 aprile! (Anche se sei negli States…)
Ciao Simo, approfitto di una veloce connessione per salutarti da Singapore, a presto, bacio!
Ciao Laura. Isn’t it sad that it is easier to trash food than to redirect it so that it doesn’t get wasted? Prepared food is a bit more difficult to handle than raw food, but I am sure there are ways to prevent good-quality food to end up in the landfill. As we all become more aware of the topic, we can exert pressure in various ways so that food does not get wasted.
Ciao Baol. Negli States e’ semplicemente lunedi’ 🙂
Ciao Astro e grazie del messaggio. Buon proseguimento del viaggio.
I’ve been thinking about Earth Day as well. I’m afraid I don’t practice what I preach, because I can’t avoid taking too many planes. Having said that, I try to avoid other damages to a world which is not mine to use, and food waste is definitely one of the things I avoid more successfully.
In Wales we basically recycled it all, apart from animal bones and a few odd items. The council made compost for us with food waste (and grass trimmings!), and you could get it back for your garden: it was so convenient. My parents have a compost bin, but honestly it is a bit stinky. Here in Germany, although the state is more committed to green energies, I found the level of recycling to be nowhere near as widespread or efficient. I love however that you pay a deposit for every glass and plastic bottle you use.
Ciao Caffettiera. City-wide yard and food waste collection is a great way to keep organic material out of the landfill. In the SF Bay Area such collection is well established, but it is difficult to get people to do it. San Francisco addressed this by making food waste recycling mandatory for business and residents. Besides being easier to handle than a compost bin, it allows recycling of items you would not be able to put in the compost bin. You can tell I am a big supporter. I also favor paying a deposit for bottles.
