Problem Statement:
Lack of awareness hinders community engagement in ongoing projects; individuals are unaware and unable to contribute effectively especially as students and the general public.
Introducing a collaborative website connecting stakeholders, project managers, and individuals. Visitors can fund, join, create, search projects, view impact and progress and actively participate in discussions and project tasks – fostering a community-driven approach to project awareness and contribution. Students can also visit the website for research and study where they can search projects and view their impacts. This is not just collaborative but also educational. We have already started working on our website. We have worked on the idea for 4 months and made a lot of reports such as SRS report, SDD report and testing too.

Introducing our revolutionary solution for a healthier planet and healthier you! We are extracting beta carotene, also known as pro-vitamin A, from the waste of palm trees that is usually burned or thrown into the Nile.

Renewable Energy Placement Optimizer

Team members:

The solution we have come up with is a tool that can tell the user the optimal location to put a renewable energy source. For instance, the user might give it a boundary of land where the energy source may be placed. The tool then utilizes AI and ML to pinpoint the places where solar panels or wind turbines would produce the most energy. The end users would range from homeowners wanting to be off-grid, to utility companies looking to build a new wind or solar farm, to government agencies looking for the best places to zone into residential areas that can be energy-self-sufficient like for the homeowner wanting to be off-grid.

Our proposal is to manage food waste in cities through a platform that connects producers with business establishments and city beautification initiatives through inventory monitoring. Biodegradable waste for compost from business establishments will be collected through city garbage collection which may then be used by farmers for planting produce, schools, foundations and city initiatives focused on beautification and carbon sinking. This network can reduce food waste and contribute to sustainable development in cities. Data monitored from users such as producers, businesses, and supermarkets, and private individuals will be used to assess their eligibility for a green score through blockchain technology. Companies may also research to create innovative materials from discarded biomaterial waste along the supply chain.

We believe that our solution promotes the food waste prevention aspect through harvest optimization by identifying imperfect & surplus produce, reshaping consumer environments through community composting which has the potential for recycling of waste-derived biomaterials through innovation.
