Our problem statement is ‘How might we automatise a plastic waste sorting bin which can sort recyclable plastic from non-plastic and plastic trash for households and schools, such that plastic recycling can be more convenient and effective, increasing recycling rates. In response, we have created a plastic waste sorting bin which can automatically sort an object placed on it into plastic or non-plastic (including plastic trash). After detecting its material, the lid of the bin will be tilted to an angle such that the lid is open and the object can fall into the correctly-labelled container. We used Arduino (to code the control of the lid of the bin) and Tensorflow (to detect between plastic and non-plastic objects).

The problem we have identified is that restaurants are unable to use up their food products before the expiry date, leading to food wastage.
Our proposed solution is to aid our consumers in better managing the products that they have purchased and ensure that they can use up these products before the supposed expiry date.by Green Food Truck

How Can we provide a safer, more convenient approach to planting, especially in HDB units? Our Changer Lego encourages a neater alternative of planting targeted mostly at people residing in HDB units, compared to carrying it out in the common corridors or in unsafe places like the ledges of each unit

The trash chute trash root is a prototype that makes use of biomimicry to trap trash deposited on the high tide lines of coastlines. Currently, much of Singapore’s coastlines are riddles with trash and TCTR helps to trap trash that would otherwise be scattered on the high tide lines of the beach. TCTR makes collecting trash a thousand times simpler as larger pieces of trash that is normally scattered at the high tide line of the beach would be trapped in the root like structure of TCTR while smaller trash would be caught in the net below. Thus the trash is collected such that it can be easily cleared by volunteers at a later date

We wanted to design an application for households so that they can greatly reduce their food wastage via improving their resource management. So we made an inventory tracking system, which can also create shopping lists and remind users of their food’s expiry dates. It sends notifications to the user when something is expired/is about to expire. A unique function to our app is its ability to double-check the user’s shopping list on whether they are going to buy something they already have in the inventory

The Gas Buster Cycle is a new rendition of the biogas machines sold in the market. It is small, less smelly and easily customisable, which makes it ideal for usage in Singaporean restaurants, hawker centres and homes. From organic food waste, we can generate cooking gases through anaerobic decomposition. Hence, it is a renewable, sustainable and clean form of energy that can reduce consumption of Liquefied Petroleum Gas (LPG).
