Pollen Season

The season of pollen is upon us, and rough winds do shake the darling oaks of March. My car is covered in yellow dust, how about yours?
Did you know that Austin’s trees provide the city with 30.8% canopy cover? Here are some other stats about our urban forest:
  • Every year, Austin’s trees remove 1,253 tons of pollutants from the air, which is worth about $2.8 million in avoided human health costs.
  • Austin’s urban trees help capture stormwater and reduce runoff, which in turn helps to reduce the amount of pollutants entering our waterways
  • By providing shade for buildings, Austin’s trees account for $4.9 million worth of avoided carbon emissions from power plants each year. This saves Austin residents $18.9 million a year in energy costs.
  • Our trees help to mitigate climate change by storing 1.9 million tons of carbon, a service valued at $242 million. On top of that, each year they sequester an additional 92,000 tons of carbon, which is worth $11.6 million.

Second-Life Uses for Batteries

Batteries often get a bad rap, since they’re associated with toxic heavy metals, acid, and other pollution that can leak into the environment if they are not properly disposed of, i.e., put in a landfill. The upside is that batteries are some of the MOST recyclable items we use, often being 99 or 100% recycled into a new product!

I’d like to take a moment to shine a light on lead batteries, an unsung hero often viewed with suspicion in the environmental world. Although lead has numerous documented, detrimental effects on health and development, and is not a thing we really want to come into contact with on a daily basis (shout out to the IH folks!), there’s a reason it is so widely used, AND it’s a recycling superstar to boot!

Lead Acid Batteries yield the following materials:

  • Plastic, often used to make new battery casings
  • Lead, generally used to make new batteries
  • Water (seriously!) that is treated to clean-water standards and released into the sewer system
  • Sodium sulfate, which is used in laundry detergent, glass, and textile manufacturing

Lead-based batteries can be infinitely recycled. They are used to store renewable energy from wind turbines and solar panels, power over 1 billion vehicles worldwide, are used in 100% of hybrid vehicles, and, by 2020, will save the equivalent of 25 billion kg of CO2 by their use in vehicles.
