Low Carbon Diet: Reducing Hot Water Usage

This will be a kind of catch all post, incorporating the other chapters we discussed last week as well, both of which had to do with efficiency of water usage. The discussion of these chapters was kind of quick and dirty, as we spent the bulk of our time sharing and discussing garbage reduction, an area that can seem like a constant struggle in our consumer society.

Water usage, while not quite as important in my discussion circle's part of the country/ world, still can make a significant impact on CO2 production, especially when heated. Climate change, too, is drastically changing the traditionally wet east coast's relationship with water, as seasonal droughts continue to ravage large parts of the South and to have significant impacts on most of Maryland. So finding ways to reduce water usage in general makes a significant difference in both CO2 reduction and environmental impact, though round these parts that means a big shift in cultural awareness of our relationship with water.

"Am I Clean Yet?"—Reducing Hot Water Used in Showers

The suggestions in the book itself are limited to installing low flow shower heads and taking shorter showers. Consider timing your average shower so that you'll have a sense of how long it takes to shower and to see how close you can get to a 5 minute shower. Heating the water for a 10 minute shower, for instance, can generate up to 4 lbs of CO2. Remember, too, that reducing that load also puts money back into your pocket in terms of fuel bills, a helpful thing to keep in mind when you long to linger.

There are some other great ideas that we discussed as a group as well, and folks raised some important points. There was a general resistance to the low flow shower heads, and several people pointed out the additional time spent in the shower trying to rinse shampoo, for instance, in a reduced water flow calling into question increased efficiency.

Speaking of shampoo, Americans in particular have a relationship with bathing that borders on the obsessive. Particularly during the dry winter months, reducing showers to every other day can be healthier for the skin as well as the environment. Shampooing, too, doesn't need to be done every day, and many people have found that their hair responds better to no washing at all, particularly those with curly hair. Some folks talk about turning the water off while soaping, often referred to as the "navy shower." In my opinion, that sounds like a mild form of torture. I'd much rather save my water by showering every other day! Young kids especially can help with water conservation by bathing together: everyone gets clean and has fun at the same time.

Bath water, too, can be saved rather than drained and used occasionally to water plants. Stick to non-edibles and be sure that you're using enviro-friendly soaps. Gray water recovery is tricky and governed by all kinds of regulations that vary by state, but it can be done. Find out more about the possibilities in your area.

In my home, waiting for the shower to heat up can waste a tremendous amount of water. Keeping a bucket handy captures that clean water for other uses, like watering edible plants, houseplants, or just pouring into your washer next time you do a load. One of our members passed around this link to SinkPositive.com, showing an easy retrofit solution to recovering clean water in the bathroom. For those building new, consider working such designs into the bathroom in the first place.

Capturing water with rain barrels can be a great way to get clean water for irrigating and can be done relatively cheaply. There are, of course, the beautiful prefab barrels that can be purchased for a tidy sum, complete with diverters for those worried about run-off from asphalt roofs, but we talked about some low-tech solutions too. Juice and soda companies can be a good resource for inexpensive, food-grade 50 gallon barrels that can be attached to downspouts with just a quick trip to the local hardware store. Here's a great website to get you started. It's amazing how much water a roof can collect in even a small rainstorm!

Another great, low-tech idea is to build a summer solar shower outside. I grew up going to the beach where we always showered outside as a way to keep the sand out of the house. While it may take some getting used to, it's a wonderful, cool, refreshing feeling to shower outside and an easy way to take advantage of the sun's power without all the fancy and expensive photovoltaics. Camping stores sell solar showers that can hold up to 5 gallons of water for easy heating and quick set up. My plan is to build a more conventional style shower by using a black storage tank in combination with a black hose snaked unobtrusively through the garden. Building an attractive shower stall for privacy near the garden takes advantage of that space while also allowing shower run-off to divert into the garden. Here's a do-it-yourself site to get started thinking about outdoor shower designs.


"Scrub-A-Dub-Tub"—Reducing Water Used for Washing Dishes

The big debate is often which uses fewer resources: hand washing or a dishwasher. The answer seems to be a very qualified it depends how you do it, but in general, the dishwasher is probably more efficient. Running a dishwasher can generate up to 2 lbs of CO2 whereas hand washing inefficiently can produce almost 3 lbs, as well as using significantly more water.

As an exercise, take a large tupperware-type container and determine the volume: some will tell you on the bottom, but it's easy enough to measure with an old gallon milk jug. Place the container under the spigot as you rinse, wash, etc. This will let you measure just how much water you go through during your normal dishwashing routine, and it will help you target where you could reduce. Pre-rinsing with a dishwasher, for instance, uses approximately a gallon of water whereas inefficient hand rinsing with the water running can use up to 25 gallons of water in just 5 minutes!

New, energy-star dishwashers can use significantly less water than older models, which also translates into less water heated by your water heater. A dishwasher with a soil sensor can tailor the amount of water to the job, and those with internal water heaters can spot heat water for dishwashing, allowing homeowners to turn down the water heater for all other household tasks. Replacing a 10 year old dishwasher with an energy star model can save more than 1,000 gallons of water per year!

There was some debate over whether pre-rinsing was necessary, as many sources suggest scraping only to reduce the amount of water used in rinsing. Personally, I've found that my dishwasher does not get things clean without pre-rinsing the dishes. What I do is keep a dish tub in my sink, which I fill while waiting for my water to get hot to wash those large pots and pans. This dish tub is enough water to pre-rinse all dishes from plates to silverware to the big pots and pans without using any more water.

Low Carbon Diet: Dumping on Garbage

This week our local Simplicity circle met to begin our discussion of the Low Carbon Diet. While I've already implemented most of the ideas and more in the book, what I'm finding incredibly useful and wonderful is the networking and idea sharing of the group. We've been bouncing ideas off each other, sharing tips and tidbits of knowledge, sharing resources and connections, and that's been sooo amazing.

The book itself is very geared towards reduction, giving "pounds" for each reduction made. The weird part is trying to figure out lost pounds if I've already done those things—in other words, I don't really get the pounds lost because my starting point was lower in the first place. So, I need to decide if I'm going to count the reduction as if I'd made it now with the group, though that seems a bit disingenuous to me, and I was really hoping to cut deeper into our current reductions.

I think what I'll do here is talk a bit about each chapter we've covered, share some of the tips we've come up with and hope that folks here will share some of their tips in the comments section, which I'll then be able to bring back to the discussion circle. So, please take the time to share what you've learned for the different categories, offer resources, and make suggestions.

Dumping on Garbage: Reducing Solid Waste

Remembering the 3 R's "reduce, reuse, recycle" and tackling them in order is the best way to eliminate garbage and waste. The book measures garbage as gallon containers, but I find that less useful than measuring the actual weight of the garbage produced. As an exercise, try weighing the amount of trash your family accumulates each week. Take each kitchen garbage bag produced and weigh it to get a sense of how much solid waste your family sends to the landfill each week.

The average American generates about 4.4 lbs of garbage per day! For a household of 5, that adds up to 154 lbs of garbage per week! My family of 5, by contrast, produces just 3-4 lbs of garbage per week through reducing, reusing, and recycling. See how low you can go!

• Reduce or better yet eliminate all food waste from the garbage by eating more left overs and composting raw vegetable scraps. 43,000 tons of food is thrown away each day in the U.S., but you can be a part of the solution. Consider setting up a vermiposting system that can handle both raw and cooked food scraps, which can be done even in urban apartment settings. Consider getting a backyard flock of chickens who will gladly take your kitchen scraps and provide delicious eggs in return. Scraping food into the garbage adds a tremendous amount of weight, not to mention odor; waste pounds can be dropped quickly by this one simple change.

• Reduce junk mail by going to directmail.com and catalogchoice.org; contact other companies directly to request mailing list removal. Recycle the rest in mixed paper bins or by sorting into office paper, newspaper, and glossy magazines if your recycling center requires it.

• Reduce packaging by buying in bulk when possible: many of us still purchase individually packaged items like cereals and snacks where the best solution is to eliminate as many of these items as possible or to buy the largest size possible. Use your purchasing power to buy recycled products or packaging that uses at least some recycled ingredients. Leave the styrofoam egg cartons in the store, folks, and go for the recycled pulp cartons instead. Better yet, buy local or grow your own!
  

• Reduce plastic bags by using cloth bags when shopping anywhere, not just for grocery stores. A great source is reusablebags.com Wash plastic zipper bags for reuse: I handwash mine and hang them over the kitchen faucet to dry. Reuse those plastic food containers instead of zipper bags and eliminate them altogether, or store items in glass refrigerator jars instead, and eliminate the plastics from your food chain. Canning jars are great for this.
  

• Reduce holiday waste. Americans generate an extra 5 million tons of waste during the holidays, much of which is wrapping paper and shopping bags, and of course parents these days know how crazy toy packaging has become! Eliminate wrapping paper altogether in favor of reusable cloth gift bags, or make your own for a personalized touch. Buy based on minimal packaging when possible; better yet, give handmade items, gifts of service, or charitable donations.

• Reduce trash by donating gently used items to thrift stores and by joining your local freecycle list. Freecycle can be a great way to get rid of all kinds of things from old appliances to leftover building materials to toys to scrap metal.
  

• Reduce waste by switching to cloth and other options for napkins, paper towels, diapers, and feminine products. Americans throw away 570 diapers per second, or 49 million diapers a day! There are many sources online for patterns to make your own diapers and pads, and products like the diva cup, keeper or moon cup can eliminate waste even further, which not only saves garbage but on the production end of such disposables as well. Switch to reusable coffee filters or loose tea. Compost unbleached paper towels and napkins like those from 7th Generation.
  

• Reuse before recycling or trashing. Many areas, for instance, don't recycle plastics other than #1 and #2. While working to change that in our community, we can reuse as many of these plastics as possible. Some ideas include: seedling containers; feed scoops; craft projects; food storage; other kinds of storage for craft or sewing items, small kids' toys, workbench organization, etc. Reuse those shopping bags. When I forget my cloth bags, I ask for paper and use those to hold mixed paper recyclables so I can toss the whole bag in the county recycling bin when full. Toilet paper rolls can be great fire starters: some folks stuff them with dryer lint, but better to turn off the dryer altogether and forgo the lint. Glass bottles and jars can be reused multiple times for storing leftovers, among many other uses.

• Reuse office paper by printing on both sides or by giving it to kids for art paper.

• Repurpose old and worn items by creating something new, limited only by your own imagination and innovation. I like to reuse broken pots and similar items as garden art, making cool and attractive homes for toads and other beneficial critters.

• Reuse those corrugated cardboard boxes to create a garden. They're great for killing turf, weed suppression, and for creating "lasagna" gardens. They can also be composted in a large active pile or by shredding. Small boxes, cardboard or paperboard, make great storage containers for the home as well. Kids can come up with hundreds of ways to reuse boxes, from forts to doll houses to treasure containers. Kids can be your best reusers, so don't overlook them!

• Recycle: set up household recycling center. Find out what your county/ province recycles and designate different areas or collection bins for each. Ikea is a great source for reasonably priced bins, though most of them aren't for outside use. I splurged for mine from Plow & Hearth, and they've held up beautifully. Newspapers can be bundled, and office paper contained neatly in bags or bins, but no one had a great system for the larger boxes, which just seem to spill everywhere. Though one person pointed out the usefulness of this in terms of reminding them to go to the recycling center!

• Recycle or dispose of those hazardous household waste products properly: computers, cell phones, batteries, oil, paints, etc. E-waste disposal: what to do with those computers and cell phones. Compact Fluorescents: what to do when those cfl's go out; those who live near Ikea can drop them off there and get some recycling bins all at the same time—kudos to Ikea for their environmental efforts. Eliminate as many of these household hazards as possible if you haven't already: check out this source for non-hazardous alternatives to many household products.
