Why Dustbin? • We wanted to take a product which is part of everyone’s day to day life…inside, outside, where ever they may go. • Dustbin is a product of daily use, but with very limited design interventions. • The regular dustbins used all around all followed the same form and similar mechanism Hence we chose this product to bring about something new to it.
What is a Dustbin…? • “Dustbin” is another name for a waste container a container for temporarily storing waste, and it is usually made out of metal or plastic. • It can be used in a variety of environments, inside or outside, based on the requirements.
Why do we need a dustbin…?
• To temporarily store trash/ garbage, without affecting the environment around it. • As we keep adding assets, we constantly require disposal of the wastes too. • To ensure neat and clean living environment…

Secondary Research Dustbin categories can be divided majorly into 2 categories: • For Outdoor use/ Public use • For Indoor use/ Personal use
Bins In Public Places – Some Categories DUMPSTERS • A dumpster is a large steel waste receptacle designed to be emptied into garbage trucks. • The word is a generalized trademark of Dumpster, a American brand name for a type of mobile garbage bin (MGB).
Wheelie Bin The "wheelie bin" is a waste container on wheels designed to make it easier for users to transport heavy loads of refuse to the curb or other pick-up point.

Activities and Interaction:
Inferences after Secondary Research: •
Dustbin as a product is very vast in terms of its design usage and functionality.
•
The following factors decide on the form, functionality and material of the dustbin design: – Whether it is being placed indoors or outdoors – Whether dustbin is being used for dry waste or wet waste – What kind of an environment it is being placed in – home, office, eateries, bathrooms etc. – What is the kind of user – kids, teenagers, youth, or a group of all these
•
To design a dustbin for public places would require a much deeper research and understanding of a lot of factors Disposal system
•
For residential interiors, there is more scope of exploring the basic form, mechanism and materials since the environment allows us to be able to do that
Hence, after the secondary research on dustbins, we focused our area of further research specifically to hostel interiors. The primary research conducted thereafter was based on the usage of dustbins within hostel room interiors, specifically studying the users of Alpana Hostel, NID PG Campus, Gandhinagar.
Primary Research: Purpose of survey/ research: • To understand the user, environment and behaviour with respect to a dustbin usage • To identify the activities and interactions of the user with the dustbin • To identify key problem areas that the targeted user might be facing • To understand user expectations • To analyse the possible placement locations for the dustbin
Visual Observations:

Activities and Interaction:
Research Analysis : • 80% of the people interviewed were students of Alpana hostel • 13 boys and 7 girls were interviewed • All students use dustbins – 70% keep them inside the room, while 30% keep them outside • The dustbins are cleaned and waste it disposed off by service providers • There are a variety of dustbins all around the hostel • Most people consider LID, HANDLE and EASE OF DISPOSABILITY while buying a new dustbin • Most students DO NOT use plastic bags inside the regular dustbins, but instead use a regular polybag as a waste container directly.
What issues we see… • Outside of the dustbin gets dirty • Inside gets dirty, and people unwilling to clean • Starts to smell • People use plastic bags on inside of the dustbins to collect waste – which is not sustainable to the environment.
• Open dustbins with biodegradable waste cause health issues • Insects find their way inside the dustbin – again health concern • Foot-presser lids don’t last long • Carrying handles are not present, or are inconvenient
• Dry waste and wet waste get combined, causing bad stink. • People too lazy to go to dustbins and throw waste. • Aesthetics not very appealing as per the environment • No standard dustbin or waste disposal methods
What users expect… • Dustbins which have self cleaning or disposable elements • Hygienic • Appealing aesthetics • Ease of disposability • Element of customization • Better if interactive!
Defining the Design Brief: Project Statement: • To design a dustbin for use in hostels – specially keeping in mind the setup of Alpana hostel, NID PG Campus, Gandhinagar
• To standardise the dustbins and waste disposal system throughout the hostel Problem Statement: • The design should aim at least possible hand contact by the user • It should ensure easy disposability of waste • Must require least cleaning and maintenance • Design should help to keep dustbins surroundings also clean • Good aesthetics

Moving Towards the Final Concept: Rough sketches :
Based on the initial idea of the form and functionality, we made various models and prototypes to understand the working and functionality. In order to make the correct to-scale model, the following things needed to be kept in mind: • • • • •
Sizes of the most commonly available polybag Technique to insert the polybag Load limit Wall mounting techniques Opening shape and form

FINAL PROTOTYPE BASED ON THIS CONCEPT…
Main Body :

Limitations of Prototype: • Plastic bag still being used; need to think of a more sustainable material to hold waste. • Design still requires hand contact • Initial concept was wall mounted , so not movable • Limited load capacity • Technique of wall mounting requires more exploration so it can hold the weight of the dustbin. • Not suitable for sharp objects. • The circumference of the current design is fixed, so the Polybag/ waste bag size is fixed • Too much material is being used for the basic concept – material use can be reduced with further explorations and prototyping.
Further Concept Generation: Based on the problem areas identified after initial prototyping, we further modified the basic concept for including improvements. Key problems areas identified for further improvements: • Plastic bag needs to be substituted. • The circumference needs to be adjustable or customizable • Must make the entire dustbin mobile, • Must have a lid
Concept 1: With Stand and Lid Sketches :
Software Rendering:
Concept 2: Key points : • The design has 4 slits instead of 2 in the cylindrical form • Hooks with metal rods are attached along the inside of the cylinder, passing through the slits • These 4 hooks can hold a polybag (on 4 ends), then the handle is pulled up, and the polybag fixes itself in the slits without direct human contact – on the inside of the cylinder • When pulled up through the slits, the sheet forms a pouch to hold waste • Once the pouch gets full, push the handle down again and remove the sheet to attach a new one.

Revisiting The Brief :
Concept 1 addresses the following problems: • Has a stand, so is movable • Has a lid • Has presser foot mechanism, so least contact
Concept 2 addresses the following problems: • Has a movable mounting concept, so is a good option. • No contact with floor, so floor remains clean. • Uses square sheets instead of polybags, so can be any material as per the user’s needs. • Since there are 4 hooks, and polybag is mounted on the inside, so more flexibility of size. • Since the waste bag is now inside, the outside can have good aesthetic additions in terms of graphics. • Has a concept of pushing up and down of hooks – so less contact of user with the bin’s body – only needs to attach sheet to hooks. • Easy disposability. • Requires lesser maintenance.
What Still Needs to be Addressed •
Limited load capacity
•
Still depends on the use of plastic sheets – although has the option of using a temporary alternative
•
The material around the edge will still tend to get dirty
•
Too much interaction between user and product
•
Marketing strategies have not been worked upon
•
Costing has not been analysed yet
