Sustainable Development Goals & a Circular Bioeconomy

The Sustainable Bioproducts & Bioenergy Program Program Goals

1. Create a professional development program for high school teachers 2. Promote awareness and interest in Bioeconomy Careers with bioproducts and bioenergy lesson activities for high school STEM disciplines.

SBBP Program Overview for Teachers

Bioproduct/Bioenergy Lesson 1: Energy Diagram

1. 2 min: Think, Pair, Share on renewable/nonrenewable energy resources 2. Short whole class discussion on energy resources 3. Compare Sankey Diagram 2008 vs 2018 and identify 4 changes between the two diagrams and present findings. Discuss why you think the changes occured.

Bioproduct/Bioenergy Lesson 2: Carbon Footprint and Recycling Projects

Sanjana Sharma’s Video 11 minutes

Why? Conserve natural resources Free up landfill space Reduce green- house gases Save energy

• f paper was recycled in 2018

Bioproduct/Bioenergy Lesson 3: Recycling Paper

Types of Contaminants:

• color
• staples
• paperclips
• sticky-notes
• ink
• dirt
• etc.

Bioproduct/Bioenergy Lesson 3: Recycling Paper

• 1. Blend paper into recycled pulp slurry
• 2. Remove ink particulars using flotation and the addition
• f a surfactant
• 3. Make a handsheet of the “cleaned” pulp
• 4. Quantify contaminate removal
• 5. Optimize contaminate removal using a design of

experiment

• a. Possible variables to change: amount of

surfactant, length of flotation, water temperature

Flotation 1. Tear one sheet of paper and blend for 45 seconds 2. Move blender to aluminum tray 3. Fill blender to the lip with water 4. Add 5 drops of surfactant 5. Place air pump into blender and turn on for one minute while scraping the foam over the side

• f the blender as it bubbles up

Making a handsheet 1. Submerge handsheet mold in water inside the plastic tub 2. Add the pulp into the handsheet mold 3. Lift mold carefully and allow to drain then place on flat surface 4. Remove the top of mold 5. Place 2 blotters on the wet pad and press with hand 6. Remove blotters and lift the sheet

• ff the handsheet mold

Reflection on Activities

1. What are your major takeaways from these activities? 2. Could you envision implementing similar activities in your teaching/learning environment? 3. Do you have suggestions for modification/differentiation for other teaching/learning environments? 4. Other comments and questions?
