Waste Management

A One Day Design Challenge.
Chalkpiece along with School4Change school conducted a one day design challenge to reduce the amount of waste produced to 2kg from 6kg in the region of Thiruvotriyur


We are a group of Designers , incorporating and addressing the pressing need for experience design to solve Social problems. We aim at building a design-driven ecosystem where design augments emerging technology and bring in the next level of disruption for the innovative product.


School4Change is a NGO who have been running free night school for Government school students for the past 14 years in Thiruvotriyur. They work with a proper structured syllabus. Nearly 2500 students passed out from their night school.

Why Reduce Waste?

Improper methods of waste disposal leads to high environmental risks which have serious effects on our future.
Waste disposal involves various processes, including collection, transportation, dumping, recycling, and treatment of different kinds of wastes. The hazards of waste disposal and Awareness about the waste management has to be raised in every household and to every young generations
Waste Segregation
Design Thinking approach
Waste Awareness
Door Campaign
Reduce, Reuse, Recycle

Our Solution

Chalkpiece along with Design4School organized an event for School children to inculcate the ideas of waste management. The students were divided into teams, each team was given a problem statement and were asked to come up with a solution to reduce waste disposal.

House Hold Waste

The Team 1 emphasized about house hold wastes and how it can be reduced, reused ad recycled. The group of students created a model to collect wastes separately and took to the households to address their difficulties and collect feedback about the ideated model. The model was highly welcomed by the households and awareness was created among everyone including the kids on the importance to reduce waste generation and how to safely dispose them and recycle the things that could be without wasting them.

Class Room Waste

Wastes collected at school level can be made easier by implementing the process first in each classroom. The Students of team 2 came up with a creative idea to collect biodegradable and nonbiodegradable wastes separately. They created 2 prototype baskets with signs pasted over them to identify the type of waste and suggestions pasted above to reduce the production of wastes. Prior to this, a survey was conducted by the students in other classrooms and their friends and found that many of them did not know about the difference between biodegradable and non-biodegradable wastes. The prototype was then used to make them aware of the difference and as a result the kids in the neighborhood pledged to reduce the wastes and that they would separate them before throwing to ebale the 3R process.

School Waste

Students used the data collected from the school watchman and sanitarian and used it to come up with a prototype to segregate and reduce the amount of waste collected overtime. They came up with a simple, yet unique design with four compartments to collect chemical, food, biodegradable and non-Biodegradable wastes separately. The students inquired about the pricing to recycle per kg of non-biodegradable wastes from a nearby recycling shop. And came up with a neat pricing plan in order for the school to retrieve some They suggested an idea to use the biodegradable and food wastes to create manures. The overall idea was to implement Recycling and to utilize degradable wastes without any leftovers.

Shop Waste

In order to control the usage of plastics in large shops and shopping marts, the students of Team 4 came up with an idea to distribute paid recyclable bags and bottles. The idea was to distribute biodegradable bags and bottles to carry groceries, things and buy liquids like oil using a token system. The Machine specifically installed for this purpose can be used to get the bags and bottles by inserting a token which can be purchased from the store owner. This process may enable people to reduce the usage of plastic bags and plastic bottles when they shop. Also, liquids like oil can be purchased in the glass bottles and this in turn can reduce the usage of plastic packets used to distribute oil.

Road Side Garbage

All the wastes are collected and disposed by the corporation from households in a locality. Team 4 suggested an innovative way to overcome the difficulties of foul smell and waste disposal by creating a Garbage collector. They suggested separate vehicles to collect the two types of waste and rather than usual way wherein the vehicle is open this model would have a side slit to dispose waste and the vehicle would be covered to mask the foul smell. From the data collected in their locality it was visible that people there already separate the wastes. But the only problem was the was smell and difficulties they face to understand the type of waste. The students even went beyond and came up with an idea to create an App to track the vehicle and how manufacturers can print the whether the packaging and their product is biodegradable or not


The one day workshop had a great impact on the people of Thiruvotriyur. As a team overall we were able to reduce around 3 kg of waste per family and a total of around 40 kg of waste generated from families within 1km of the locality
