INTRODUCTION WHAT IS ENERGY Energy is the measure

INTRODUCTION

WHAT IS ENERGY? • Energy is the measure of the ability of a body or system to do work or produce a change. • The total amount of energy in the universe is fixed. Energy can neither be created nor destroyed. • However, the amount of energy available to do work decreases as it is transferred from step to step in a process. This is why using energy efficient methods is important!

POP QUIZ… This presentation includes an interactive component using Turning. Point software. You will be asked a series of questions at the start of the presentation and again at the end to help us measure your change in knowledge. Questions are answered by using the remotes handed out. Let’s do a practice question!

URBAN COMMUNITIES • 80% of the population lives in urban or sub-urban areas. • Urban land takes up 30% of land area. • Struggle with finding a place for everyone as more people move to urban areas.

URBAN RECYCLING • Usually requires little work from the resident other than paying a fee. • Funded by local government. • Most materials can usually be recycled including scrap metal and hazardous waste. • Processing is more intensive. • Cities can make money off selling recyclables to private manufacturers.

DUAL STREAM RECYCLING “Curb-Sorted" Mixed paper is sorted separately from metal, plastic, and glass.

SINGLE STREAM RECYCLING • All paper, cardboard, metal, plastic, and other recyclables are collected in the same bin. • Allows for greater collection efficiency and eliminates the burden on residents to sort recyclables. • Greater efficiency reduces GHG emissions from collection trucks. • Typically yields more recyclables collected.

RURAL COMMUNITIES • 20% of the population lives in rural areas. • Rural land takes up 70% of total land area. • Rural inhabitants struggle with maintaining population and economic opportunities as more people move to urban areas. • Often overwhelmed or pushed out by urban sprawl.

RURAL RECYCLING • Typically feature centrally located collection centers for residents to bring recyclables to. • Requires more input from the resident and may require driving some distance to get there. • May not take as many types of recyclables as cities, meaning many items don’t get recycled at all. • Operated by local government or private groups. • Sends collected materials to a regional, state, or private processing facility.

WHAT CAN BE RECYCLED?

WHAT CAN BE RECYCLED? Hazardous Waste • Includes cleaning chemicals, paints, automotive fluids, batteries containing heavy metals, and CFL bulbs. • When these items get thrown away instead of recycled, they can leach harmful contaminants into the environment. • Typically can be brought to a specialized HW facility or sometimes an auto-shop. o Check with Earth 911. com for your local center.

WHAT CAN BE RECYCLED? Metals • Includes food and drink cans, scrap metal, and aluminum foil. • Aluminum is 100% recyclable, meaning it can be recycled over and over. • Uses a fraction of the energy to make new cans out of recycled materials as opposed to new materials. • Aluminum cans are typically accepted by local recycling program. o Scrap metal may require drop off at a specialized facility.

WHAT CAN BE RECYCLED? Paper • Cannot be recycled indefinitely as the fibers eventually wear out. • Recycled paper can make over 5, 000 other products. • Usually picked up curbside or at centralized collection centers.
