challenge 1

Responsible and innovative use of materials and reduction of non-biodegradable waste

This is an engineering challenge that involves the responsible use of materials and innovations that will ensure that the materials can be recycled and reused. The challenge is to develop a product, solution that addresses the resource challenge, or a system to recover and reuse materials.

 

You might start by considering the questions, what waste streams you are familiar with or can see impacting in your local community, what scientific knowledge could tackle the problem, and how to meet the requirements of easy to use, economical affordable, safe and environmental friendly, etc.

 

Your solution should be consistent with the theme of World Engineering Day 2022

Build Back Wiser–Engineering the Future.

Examples Include:

Extraction of precious materials from mobile phones
and e-waste.

Development of new materials that are strong and biodegradable.

Reuse of rubber, polyurethane and other polymers that do not biodegrade easily.

Development of materials from natural resources such as fast-growing bamboo and other timbers.

UN Sustainable Development Goal

The Challenge addresses the UN Sustainable Development Goal 12

Responsible Use of Resources

Our planet has provided us with an abundance of natural resources. But we have not utilized them responsibly and currently consume far beyond what our planet can provide. We must learn how to use and produce in sustainable ways that will reverse the harm that we have inflicted on the planet.

Participants may nominate additional SDGs that are addressed as part of their solution.

BACKGROUND

There is an imperative to manage the transition away from certain waste streams, as a solution which has a positive impact for the environment may actually have a negative impact on vulnerable communities.

If the ‘more-sustainable’ alternative is not also affordable and appropriately-designed, this could limit access to important products for some communities. For example, some single-use plastic products such as menstrual pads and baby nappies are currently often much cheaper per unit than alternatives made of more environmentally-friendly materials.

It is imperative to mitigate impacts on low-income communities by providing economical alternatives which are also good for the planet.

Examples in Practice

  • Tackling harmful tyre emissions 
  • Turning waste crustacean shells into biodegradable, compostable products, providing a plastic packaging alternative 
  • Clothes that grow with children
  • Extraction of gold and precious metals from mobile phones
  • Reuse of polyurethane foam for manufacture of acoustic tiles
  • Extraction of biosolids from wastewater streams for energy generation, reducing landfill
  • Reuse of tires in steel making, as a source of carbon 
  • Turn waste into green building materials

Submission Guidelines

This guidelines has been designed to support the development of an engineering solution that demonstrates a considered response to one of the engineering challenges and also how one or more of the UN Sustainable Development Goals (UN SDGs) are advanced through engineering.

Solution Considerations Overview

The success of an engineering project depends on much more than just the technical feasibility of the initial concept but also consideration of human factors, environmental context, cost and economic benefits, etc., are very important to the successful implementation of any innovative and ‘technically-sound’ idea.

 

Below are a series of considerations we recommend you factor into your solution to ensure it is appropriate to the context where it is to be implemented. You might ask yourself these questions a few times throughout the development process – it’s okay if you don’t have all the answers right away! How can you build on your original idea, to improve it each time?

 

Most effective technical solution for the context

 

  • Is the technical solution the most appropriate and effective for this context? Take the time to show what alternatives were considered and why you are proposing this solution as the most appropriate. What was the process you went through to determine this idea was the best one? How have you demonstrated the technical feasibility of this solution?

 

  • How might you construct and/or implement the project? Is your solution one that considers local capacity for ongoing management, repair, and maintenance? As much as possible, does your solution or system proposal align with locally available expertise?

 

Environmental sustainability outcomes

 

  • What Sustainable Development Goal does your solution idea contribute to? How? Are there any relevant indicators that might be useful to incorporate into your submission? Have you considered the carbon footprint of your proposed product or system?

 

  • What impacts, both positive and negative, will your solution have on the local environment? What measures would you propose be put in place to mitigate any negative impacts?

 

  • Consider the long-term sustainability of your project proposal. What is the life-cycle of your project or solution? What measures could be put in place to ensure either successful continuation into the future or a successful end-of-life process?

 

  • Have you considered the use of locally available materials that are contextually-appropriate and environmentally-friendly wherever possible? Transportation of project materials and availability of materials which might be required for future maintenance are a significant consideration for projects in many locations. Where might your proposed materials be sourced from?

 

  • Have you considered the resiliency of your solution to climate change and disasters?

 

Engagement of key stakeholders

 

  • Who are the individuals, organisations, or networks who might be impacted (positively or negatively) by your idea? What might these impacts be? Now think again, is there anyone you haven’t included?

 

  • How would you propose a project implementing team engage and consult these stakeholders throughout the project? Think about the initial solution right through to implementation. What avenues are there for community members to become involved? What form(s) of community engagement might be required for your particular solution?

 

Are there any ethical considerations – such as adverse impacts to the environment, economy, social inclusion, culture, community, resource use, that warrant consideration?

 

  • Incorporation of cultural and social factors, specifically the integration of indigenous knowledge or practices

 

  • Does your solution align with and/or celebrate the cultural and social practices of people who live and work in your project context?

 

  • If relevant to your proposal area, what might Indigenous-led solution look like?

 

How has your team utilised digital tools, for example to develop models of your proposed solution as part of the solution. Also how the team has utilised ICT in the process of putting forward your submission.

 

Cost estimates and economic and non-economic benefits

 

  • What is an estimated cost of the project? Think about the ‘capital expenditure’ (initial cost to start) and ‘operational expenditure’ (ongoing costs over time), which might include materials, implementation costs, operation/program delivery costs, and maintenance costs. What trade-offs might you be making in your cost assumptions? 

 

  • Are there are any potential economic and non-economic benefits to community stakeholders which could result from the project?
