🛠️ The Sustainable Waste Engineering Challenge: A STEAM-Based Game ♻️🌍

💡 Concept:

Students (16 years old) will take on the role of environmental engineers tasked with designing an innovative, zero-waste system for a fictional city, school, or event.

They’ll apply engineering principles (systems design, prototyping, efficiency analysis) and creative problem-solving to develop high-impact waste management solutions.

🕹 Game Setup & Rules

• 📌 Teams: Groups of 4–5 students
  
  
• 📌 Objective: Design the most innovative and effective waste management system
  
  
• 📌 Time Limit: 60–90 minutes
  
  
• 📌 Winning Criteria: Highest points for engineering creativity, environmental benefit, and feasibility
  
  

🔹 Round 1: Waste Systems Analysis (Process Mapping & Engineering Flowcharts) 🗺️🛠️

💬 Challenge: How does waste move through the system?

• ✅ Task: Analyze a fictional location’s waste system and map it as a flowchart.
  
  
• ➤ Goal:
  
  
  1. Identify waste generation points.
     
     
  2. Diagram collection, sorting, and disposal paths.
     
     
  3. Detect inefficiencies or system gaps.
     
     

🎯 Points for: Logical layout, completeness, and system insight.

🔹 Round 2: Smart Sorting Mechanism (Mechanical & Systems Engineering) ⚙️🤖

💬 Challenge: How can sorting be automated?

• ✅ Task: Design a conceptual or physical prototype of a waste-sorting mechanism.
  
  
• Options:
  
  
  1. Conveyor system with color sensors
     
     
  2. Robotic arm that sorts by material weight
     
     
  3. Gravity-fed bin system for paper, plastic, and compost
     
     
• ➤ Goal:
  
  
  1. Choose components and layout.
     
     
  2. Justify your design based on reliability, simplicity, and effectiveness.
     
     

🎯 Points for: Feasible design, smart automation ideas, and practical integration.

🔹 Round 3: Upcycling Engineering (Product Design & Material Science) ♻️🧠

💬 Challenge: How can we turn trash into usable goods?

• ✅ Task: Select a waste stream (e.g., plastic, cardboard) and design an upcycled product or infrastructure piece (e.g., park bench, insulation panel, wearable item).
  
  
• ➤ Goal:
  
  
  1. Create a labeled sketch or basic prototype model.
     
     
  2. Describe tools, processes (cutting, molding, etc.), and safety considerations.
     
     

🎯 Points for: Innovation, durability, usability, and sustainability.

🔹 Round 4: Infrastructure Redesign (Civil & Environmental Engineering) 🏗️🌿

💬 Challenge: What physical changes can support better waste management?

• ✅ Task: Redesign a key area (e.g., school cafeteria, city square, festival venue) with embedded waste-reduction features:
  
  
  1. Smart bins
     
     
  2. Composting stations
     
     
  3. Waste-sorting zones
     
     
  4. Reuse stations
     
     
• ➤ Goal:
  
  
  1. Use spatial reasoning to draft a layout.
     
     
  2. Annotate features for flow efficiency, safety, and accessibility.
     
     

🎯 Points for: Space optimization, user-friendliness, and eco-effectiveness.
