A community with environmental and healthy resources
Hello again and a happy Friday to everyone! It’s the end of another week and I’ll continue here our series on Green Labs. This time we’ll have a look at the other side of the world, i.e. at the Green Labs Program at the University of Queensland in Australia. It’s part of a larger initiative of the university promoting “sustainability across all aspects of learning, discovery, engagement and operations” and features a nice collection of Green Labs Fact Sheets, which contain lots of tips for running a lab more environment friendly. Especially one of them caught my attention and that’s the fact sheet on water consumption.
Let’s assume that you haven’t read the UQ’s fact sheet yet (or just pretend that’s still the case) and imagine that you’re asked, “where in the laboratory do you use water?”. Of course, there are the activities, which everyone does: washing you hands, cleaning lab equipment, using water to dilute or prepare solutions. That’s what came to my mind. Now looking at the UQ’s study (see picture below), this does indeed account for 25% of the water consumption. But would you have guessed that the air conditioning system uses much more water, i.e. 42%?!? Well, I guess the fact that Brisbane has a humid subtropical climate might contribute to that and it might look different for universities with a more moderate climate. And even if one might not be able to do much about it (in this case, it’s up to the Property & Facilities Division … unless you can adjust the air conditioning in your room? If someone’s working at the UQ and could comment on this, please do so!), it’s good to be aware of this.
And one can definitely try to do something about the remaining 68%, i.e. the use of water for sanitary purposes and for the usual lab processes. For example, when you clean the labware, run the dishwasher only once it’s fully loaded or don’t let the tap water run all the time. Or at least not at full throttle – usually a reduced flow rate is still more than enough. Look at the example given in the fact sheet, where a test with reduced flow rates for autoclaves indicated a possible reduction of 62%, which translates into savings per autoclave of over $2,000 a year. Not bad at all, isn’t it?
Also, some of your cooling lab equipment might work with much less water. Again, the fact sheet give a nice example here: instead of letting the water run through the cooling apparatus just once, it’s possible to circulate it a few times before the water becomes to hot and goes down the drain.
Besides all the helpful tips, this fact sheet taught me that there might be some equipment using water that I wasn’t even aware of. And awareness is the first step, isn’t it? So, let’s be more aware about when and where we’re using water. And then let’s take the next step and take actions to reduce our water consumption!

So you’re thinking of herb gardening, or maybe you tried it last year and it was an utter disaster? Have no fear. There are a few simple mistakes that many herb newbies make (and I know, because I made most of ’em myself). Master these simple and practical tips for herb gardening and you’ll be using your own fresh herbs like Mario Batali in no time.
Fresh herbs are one of the greatest ways to increase the taste of your food healthfully. I often toss whatever leafy herbs are hand liberally into a salad to add unexpected variations in flavor (basil, oregano and dill are all great choices). Fresh herbs can add punch to sauces or create intensely flavorful crusts for roasted meats. While fresh herbs are now regularly available at grocery stores year round, growing your own herbs is a great way to build mastery over your food. Growing herbs at home can be easy whether you live in a house in the suburbs or an apartment in the city.
Let it be known that I have the blackest of thumbs. I routinely kill houseplants and whether from too much love or too much neglect I never really know. Moreover, I live in a condo in Chicago, so I only have pots on my back fire escape as my city “garden.” In fact, I’ll argue that it is my black thumb that gives me the bona fides to give beginner gardeners tips, because I have figured out how to grow herbs and am painfully aware of every lesson I learned along the way.
It surprises me how often I bump into friends who are flummoxed about some aspect of herb gardening. And strangely, I feel there are few practical guides to growing herbs on the internet for someone just starting out. Most of the advice is geared towards high end gardeners who can make sense of soil PH and whatnot. When I was starting out, what I really needed was some sort of herb gardening for dummies. So here is my quick and practical advice for growing herbs for beginners. Continue reading “Ten Mistakes New Herb Gardeners Make (and How to Avoid Them!)”
