Pre-fieldtrip Homework

1. The Redwood Landfill provides a safe and environmentally sound space for waste disposal and has done so for the past 50 years. They take all sorts of waste but recycle about 50% of the materials brought to the site.
2. Some options that replace landfills are waste reduction and increased recycling. It is also possible to use incinerators as an alternative to landfills, where trash is burned rather than compressed and stored. This can cause high levels of pollution to surrounding areas and contributes to green house gases in the atmosphere.
3. Landfills are cheap and convenient, but they have flaws. There are often issues with the toxicity of what is put in them, and the pollution they cause to areas around the landfills. Trash is then sometimes burned, which pollutes the atmosphere.
4. The Marin Recycling Center handles all of the recycling done in Marin. They have a goal of zero waste, and have initiated the first curbside collection program to happen in the United States.

  1. Anna very short and succinct replies. Develop the alternatives to landfills more. For example incinerators are an option. What are the pros/cons of incineration?
