According to the Lower East Side Ecology Center, the Department of Sanitation in New York City collects 13,000 tons of garbage everyday, and almost 5,000 tons – close to forty percent – account for organic materials that could be composted. Composting not only reduces waste, it also saves greenhouse gas emissions from refuse transport and provides nutrient-rich plant food for gardens, yards and parks. Because the health of the planet plays an important role in our own health, composting is something to be taken seriously and everyone can participate. Many urbanites wouldn’t consider composting compatible with city life, but surprisingly, it is.
Get Started
Worm bin composting requires few materials, little maintenance and less than three cubic feet of space. Properly managed, worm bins are discrete and odorless, and they do not attract pests. Bins can be tucked away inside a closet or pantry, under the kitchen sink, or in any shady spot, as long as the air vents are unobstructed and the temperature remains between 50 and 80 degrees Fahrenheit. A standard size bin, sometimes called a Worm Condo, usually measures 12 by 16 by 19 inches, but any lidded plastic container of similar size, with air holes and drainage holes, will work well.
To set up a worm bin, begin with bedding materials referred to as “greens” and “browns.” Greens are organic materials rich in nitrogen. These can include fruit and vegetable scraps, coffee grounds, coffee filters, tea leaves, tea bags and fresh green plant materials like wilted flower bouquets, weeds and grass clippings. Browns are rich in carbon. These include newspaper, office paper (nothing shiny), paper bags, cardboard, food-soiled napkins and paper towels, dryer lint, saw dust, wood shavings, egg shells, corn cobs, stale bread and dry plant material like fall leaves, dead pine needles and dried flowers.
Place up to three pounds of green materials in one corner of the bin. Shred some newspaper into one-inch strips (you will need about five newspapers if this is the only brown material you plan to use). Dip them in water and squeeze out as much moisture as possible. Separate the strips and drop them into the bin, along with any other browns, on top of the greens. Fill the container up to the bottom of the air vents, roughly three inches from the top. All of the greens should be covered by browns. The browns should have a fluffy appearance and allow for plenty of air circulation, creating a humid, but not wet, environment.
On top of the browns, add one pound of Red Wigglers – approximately 1,000 worms – and cover the container tightly. Ensure that the air vents at the top are open and unobstructed. There should be little drainage, but a small amount is normal, so place the bin on a tray lined with an old towel or newspaper to absorb any liquid.
To maintain the worm bin, place up to three pounds of greens in the bottom of the bin each week (a volume approximately equivalent to a standard size bread bag). Imagine that the bottom of your bin is divided into six equal areas and use one area each week. Rotate your disposals around the bin, returning to the first area six weeks later. Each time you add greens, be sure to place them at the bottom and cover them with browns.
After approximately four months, the bedding will begin to resemble crumbly black dirt and the compost will be ready to harvest. Move everything to one side of the bin and stop adding greens to this compost. On the empty side, add new greens and browns and continue composting.
Two weeks later, most of the worms should have moved over to the new bedding. Remove the compost and redistribute the browns to the empty side of the bin, adding more if necessary. Use the compost you harvested to feed plants, trees or grass. If you can’t use all of the compost yourself, donate it to local farms or community gardens.
Follow Four Rules
To avoid odors and infestations, follow four simple rules. First, maintain roughly equal amounts of greens and browns inside your bin, but always add slightly more browns. Greens are typically damp materials, and if there are too many, the environment will become too wet and foster microbial growth. If this happens, add more browns, which are typically dry materials, to absorb excess moisture.
Second, refrain from adding oily foods to your worm bin. This includes salad dressings, sauces, meat and fish scraps, cheese and other dairy products. Because fats and oils turn rancid more quickly at room temperature, they can become smelly.
Third, avoid adding the skins and peels of citrus and tropical fruits to your worm bin, or treat them first. Fruit flies often lay eggs on these fruits, and eggs that hatch inside a worm bin can quickly create an infestation. To kill any fruit fly eggs before they can hatch, freeze citrus peels and tropical fruit skins overnight or heat them for one minute in the microwave (and cool to room temperature) before adding them to your worm bin.
Fourth, avoid adding anything to the bin that might threaten the health of your worms and their ecosystem. This includes pet waste, diseased plants, pesticide-treated plant materials, pressure-treated lumber, glossy paper, charcoal, weeds with seeds, invasive weeds, dead animals, and inorganic materials like plastic, metal and glass.

The Lower East Side Ecology Center in New York City offers informative workshops like Worm Composting 101, a Children’s Wormshop, and Worm Composting for the Classroom, designed for teachers who want to start class projects. They sell materials, including Worm Condos and the Red Wigglers that love them, and accept donations of organic materials for composting (approximately 1,000 households currently donate six tons per week). The Center also offers a free composting hotline to answer questions and help troubleshoot problems (212-477-3155).
Visit their website at www.lesecologycenter.org or stop by their stand at the Union Square Greenmarket any day it is open (8 to 5 every Monday, Wednesday, Friday and Saturday) to get more information, register for a class, donate your organic waste, or buy some authentic New York City compost.
Preventing Swine Flu
The upper respiratory infection caused by the H1N1 influenza virus, commonly called the swine flu, has everyone on alert. Preliminary reports suggest that most cases are limited to mild illness and unless the virus mutates or combines with a more dangerous virus, an above-average incidence of death and disability are unlikely. Immunization efforts are underway but swine flu vaccines have sparked controversy and concern over questionable ingredients and inadequate safety information. My patients frequently ask me to make recommendations for alternatives to vaccination, so here I share some simple strategies to enhance immunity and prevent infection during swine flu season.
Common Sense
The swine flu is much like the regular flu. The symptoms are similar – fatigue, fever, chills, sore throat, cough, runny nose, headache, body aches – and like other influenza viruses, H1N1 is transmitted through contact with respiratory secretions of infected individuals, usually after coughing, sneezing or touching common surfaces. To prevent transmission, avoid touching your mouth, nose, or eyes and wash your hands often with hot, soapy water and lots of friction, for at least twenty seconds. Although people can become contagious before symptoms even start, use your best judgment and avoid contact with individuals who appear to be sick. If you are ill, stay home to prevent spreading the infection to others.
Good Nutrition
While a multiple vitamin-mineral supplement can provide the nutrients necessary for a healthy immune system, it is no substitute for whole foods. Eat a wide variety of fruits, vegetables, whole grains, beans, raw nuts and seeds. If you eat meat, choose pasture-raised and grass-fed animals. If you eat seafood, choose small fish that live in cold water, like anchovies, sardines, herring and wild salmon, and avoid large fish at the top of the food chain, like tuna and swordfish. Avoid processed foods, trans-fats, hydrogenated oils, refined carbohydrates like white flour and sugar, and excessive intake of alcohol. Unless you have kidney disease or your doctor has told you otherwise, drink plenty of fluids. The best choices are filtered or spring water and unsweetened herbal or green tea.
Sufficient Sleep
Getting enough sleep is important for a healthy immune system. A study published in the Archives of Internal Medicine found that healthy adults who slept at least eight hours each night had a higher resistance to upper respiratory infections. Participants reported their sleep duration and sleep efficiency (time spent in bed asleep) every night for two weeks before they were exposed to a rhinovirus known to cause the common cold. Those who reported less than seven hours of sleep per night were almost three times as likely to develop a cold than those who slept eight hours or more. Participants who reported poor sleep efficiency (less than 92 percent) were five and a half times more likely to come down with a cold compared to those who reported a high sleep efficiency (98 percent or above). Although this study focused on rhinoviruses, sufficient sleep is most likely an essential element in preventing other upper respiratory infections, like swine flu, as well.
Regular Exercise
Exercise can also impact immunity. One study, published in the American Journal of Medicine, followed 115 sedentary postmenopausal women for one year to study the effects of physical activity on resistance to upper respiratory infections. Participants were divided into two groups: one exercised for 45 minutes at a moderate intensity, five days each week, while the other attended one 45-minute stretching session, one day per week. Researchers concluded that the stretchers had a much greater risk of getting sick than the exercisers, by a factor of three in the final three months of the study. If regular exercise can increase resistance to upper respiratory infections in older women, there is a good chance it can be helpful for the prevention of swine flu in others.
Vitamin D
Studies have shown that vitamin D can stimulate the production of white blood cells responsible for identifying and destroying abnormal cells, like the H1N1 virus, and producing anti-microbial peptides that protect the respiratory system from infection. Studies have also shown that low blood levels of vitamin D are associated with an increased incidence to colds and flu. Vitamin D production is stimulated in the skin upon exposure to ultraviolet radiation and levels may be low during colder months when we spend less time in the sun. Blood levels of Vitamin D can be tested by your doctor and should ideally fall between 60 and 90 nanograms per milliliter (ng/ml). If levels are low, vitamin D can be taken in supplement form to increase immunity during cold and flu season.
Probiotics
Probiotics are healthy bacteria that normally live on our bodies and inside our gastrointestinal tracts. These supplements are most commonly used to treat digestive disorders but studies show that probiotics can also play an important role in respiratory tract infections. In a double-blind, placebo-controlled study published in Pediatrics, researchers followed 326 healthy children between the ages of three and five years taking a placebo or probiotic product (lactobacillus acidophilus alone or in combination with bifidobacterium) twice daily for six months. Compared to placebo, the kids who took probiotics experienced fewer cold- and influenza-like symptoms, including fever, cough and runny nose, and they recovered faster when they did get sick. They reported less illness-related school absences and required fewer prescriptions for antibiotics. If probiotic supplements can be protective against the flu, they may be useful in preventing the swine flu as well.
Botanical Medicines
Elderberry has a long tradition of use as treatment for upper respiratory infections and a recent study, published in Phytochemistry, supports its efficacy against the H1N1 virus. Researchers found that elderberry flavonoids can bind the H1N1 virus and block its ability to infect host cells. They concluded that its anti-viral activity is comparable to pharmaceuticals Oseltamivir (Tamiflu) and Amantadine.
Other herbal medicines used to prevent and treat viral upper respiratory infections include Astragalus root and medicinal mushrooms like reishi, shiitake and maitake. These botanicals have been used in traditional Chinese for thousands of years as restorative tonics, immune stimulants, and adaptogenic herbs that increase resistance to stress and illness.
Good Guidance
Like pharmaceutical medications, nutritional and herbal supplements are not appropriate for everyone. Before taking anything new, talk to a doctor trained in the use of natural medicines about contraindications, side effects, potential interactions, and the best dosage for you.
