SOLID WASTE MANAGEMENT

Objectives

What is waste and how does it affect our environment?

How much waste do we have and where does it go?

What can I do to help? Waste Segregation Reduce, Reuse, Recycle

What is WASTE?

What is the ENVIRONMENT?

How does WASTE affect our ENVIRONMENT?

Kill animals by trapping them or mimicking food

Destroy habitats so animals don’t have a place to live

How does WASTE affect our ENVIRONMENT?

Waste never leaves the system until it degrades (which takes a long time!)

It can be transferred by runoff and once in the ocean washes ashore

How does WASTE affect our ENVIRONMENT?

Global Climate Change – Increase in Earth’s temperature Heat from sun trapped in atmosphere by

“greenhouse gases” Results in habitat destruction, increased

extreme weather events, plant/animal extinction How greenhouse

gases and solid waste are related: Burning of

plastics/waste releases greenhouse gases

Production of new materials (when items are not recycled)

How much WASTE do we have? Average Filipino generates 0.4kg

waste/day Population of San Antonio ~ 32,494

people

32,494 people X 0.4kg = 13,000 kg waste per day

8,000kg X 365 = 4,745,000 kg waste per year produced in SAN ANTONIO ALONE!

What do you DO with WASTE?

What do you DO with WASTE?

Archipelago of many islands

Many mountains and coastlines – not many ideal places to store solid waste

Runoff/leaching from improper storage can damage sensative and valuable ecosystems (eg. Coral reefs)

How can YOU help the ENVIRONMENT?

3 Principles of Waste Management -

Reduce Decrease amount of waste at the

source Reuse

Use a would be waste item again Recycle

Turn waste into something else

How can YOU help the ENVIRONMENT?

REDUCE

How can YOU help the ENVIRONMENT?

REUSE Durability = less waste GET CREATIVE!

How can YOU help the ENVIRONMENT?

RECYCLE – waste that can be traded in for money!

Glass Aluminum Plastic

Materials Recovery Facilities

Creating a Materials Recovery Facility (MRF) can be a great way to start the process of solid waste disposal in an evironmentally responsible way

Segregate solid waste for next level of processing: sell recyclables, compost biodegradables and reuse plastics

Environmental Club

Now that you know how to save the environment – pass on the information!

Starting an environmental club can inform and empower students to make better choices about their environment!

Environmental Club

EcoBank – School run MRF that sells recyclables to the

highest bidding junk shop Each student’s contribution is logged and at

the end of the school year they receive 75% of their contributions, and the school keeps 25% for student activities

In only 2 months a school in Batangas has raised >19,000 php
