"A serving of juice generates up to 4.5 pounds of pulp, depending on the ingredients. So where does all the leftover cucumber, mint, kale, apple, and carrot go?
A single 16-ounce serving of cold-pressed juice generates, on average, 3.5 pounds of pulp waste. The amount of pulp waste estimated to have wound up in landfills last year totals 175,000 tons. The end result:
The methane generated as the pulp decays is equivalent to some 200,000 tons of carbon dioxide emitted into the atmosphere. (Methane’s potency as a green- house gas is 34 times that of CO2 on a 100-year scale)."
But of course the story is more complex, with some juicer companies composting their juice pulp (with various degrees of success) or saving food waste by using imperfect-looking fruits and vegetables which would otherwise by discarded by farmers, supermarkets and consumers.
