Organic food waste dumped in landfills
The sustainability challenge I am addressing revolves around organic food waste management generated by households. Specifically, I focus on organic waste, excluding leftovers, typically discarded directly into garbage bins dumped into landfills.
The negative impact is significant, spanning household financial losses, nutrient depletion, high disposal costs, and contributions to greenhouse gas emissions and environmental pollution.
As a business enthusiast, I am inspired by the untapped market potential. While many businesses and startups are targeting opportunities like plastic, paper, and even foil waste, there is a lack of clear solutions addressing organic food waste at the household level.
I think this contributes to more than one SGD
SDG 3: Good health and well-being
SGD 4: Affordable and clean being
SGD 11: Sustainable cities and communities
SGD 12: Responsible consumption and production
Explain your impact assessment on those four pillars: social, economic, environmental, and natural resources. And, explain how this assessment will influence your project concept and goals.
> Social impact:
1. Does your project address the need to reduce household organic waste and its associated environmental and economic impacts?
Yes, the project directly reduces the amount of organic food waste by using it as an input material for paper upcycling. This is based on each household's consumption.
2. Can your production process involve community participation or create opportunities for skill development and income generation?
It indirectly contributes to saving rather than income generation. Household users, mostly women, would use this solution on a micro level.
> Economic impact:
1. Can your upcycled paper product find a viable market and generate revenue to sustain the project and expand its reach?
There is an existing niche market for environmentally aware users. However, for scalability, this project could be done on a B2B scale with different specs that would suit a larger upcycling capacity.
2. How can you minimize production costs and ensure the upcycled paper is competitively priced compared to traditional paper products?
most of the paper we use is imported from other countries. However the household upcycling alternative nearly costs 0 material.
> Environmental impact:
1. How will your upcycled paper product encourage sustainable practices among consumers?
The process of turning waste into paper is engaging and fun, which will invite potential users to explore
2. How can you ensure the upcycled paper is biodegradable and compostable, minimizing its environmental impact at the end of its life cycle?
For now, I am not sure to which extent the alternative upcycled paper will be environmental. However, the newly created paper needs fewer resources overall.
> Natural Resources Impact:
1. Does the project ensure the responsible sourcing of organic peels?
yes, since it's resources inside each household based on usage and consumption (relative)
2. Does the solution ensure your production process minimizes the consumption of water and other natural resources?
Yes, since it solves the problem on a small micro level with limited resources and upcycling features
CONCEPT 1: FROM ORGANIC PEELS TO SOAP/CANDLES
I want to create a DIY molding machine for organic food peels, mostly vegetables, and fruits, so that I can upgrade the peels into a functional product used in households like soap and wax for home use only, not commercial use.
The cold process of wax-based product-making using a molding machine usually requires drying and grinding the peels, heating and blending with binders, molding, and cooling.
The process in steps:
Grinding the dry peels
Melting the peels with the binder
Pouring the liquid into the mold (mold part)
Cooling OR leaving it in the room temp. to dry
CONCEPT 2: FROM ORGANIC PEELS TO PAPER SHEETS
Creating a machine does the following
grinding/pulping the peels (this process requires water to create a paste) - (After the feedback, I decided to remove this part of the process, as it can be made as an external one.
Inserting the organic waste paste (The process will start from here)
Pressing/rolling the paste to create sheets
Drying the sheets to become usable
Construction Parts
For the chassies: laser cut plywood
For the roller: 3d printed part / presser: both would work
Input
(Sensing, Tactile Input, and/or Graphical Input)
Sensors:
Weight sensor to ensure the amount of used peels to create the required amount of sheet (main)
Temperature sensor to ensure the drying process, so that the sheet can be used (optional)
Tactile inputs:
A Screen like in the game kit to show the current status of the process.
For instance: grinding, pressing etc..
Action
(Physical and/or Graphic)
Physical:
Motorized grinding/pulping (blender-like) >> for the grinding process
Pressing: hydraulic system // pasta making like
Drying unit: fan for drying the sheets evenly to be ready for use
Graphic:
Screen display
Brain
Arduino to control the motor and the screen..
Power Management
12 V adapter for the motor I guess.
Describe how your project will leverage maker tools like laser cutters or 3D printers to reduce waste, and increase maintainability. Also, explain your choice of materials such as fabric, plastic filament, or recycled plastic sheets to support green innovation. Select materials with low environmental impact, and explain their relevance to your project.
3D printing: for the rollers that will create the paper by turning from a paste-like to a paper thickness-like. The reason why 3D printing is the most suitable is due to the cylinder form of the rollers.
The spinning handle knob (like the pasta machine) also will be created by 3d printing
Laser cutter: for the base of the project, and also for the tray that will act as a bed for the paper material to settle on and dry
The exterior that will carry the rollers will be made of plywood and laser-cutting
> This project will reduce waste by upcycling household organic waste every day. The project will turn the repurposed waste into upcycled recycled paper
Also, for the base part, recycled plastic can act better as an alternative for the plywood and more sustainable in case the peels can be extra moist

Concept 2 (post research and development)
After further research, I noticed that the DIY-making process needs water for the pulp (organic material) to get put together and create the paper. Plan A has a reservoir at the top above the rollers to feed the rollers with the material and then the motor rolls the rollers so the material gets thinner to the thickness of the paper.
However, this plan did not consider the water amount needed for paper creation while thinking that the process starts from top to bottom. In addition, the pulp material is too weak during the making process to be rolled and handled unprotected.
So, I decided to flip the material insertion process from bottom to top or from left to right.
As for the steps:
In an external bowl, the material will be prepared: the pulp (organic food waste after some grinding). Then add the needed amount of water to the pulp, maybe some binding material.
Afterward, place the prepared material on the plate and add a strainer sheet above and beneath.
Then, a press plate on the top before the pressing starts
Then, I will start running the knob for pressing, and then the paper material will squeeze out all the water inside.
Here's a close reference to a DIY paper kit for paper making using ready-made pulp material for the paper and pigment as an option. The whole process is considered manual, However, for creating a smart project, I will add motors and sensors for a usable

Enclosure/hard material:
an body for containing the motor
a tray for the pulp to settle and get pressed on
a pressing tray to be placed above the pulp tray
a tray from beneath that acts as a collector for all the water that will get squeezed out of the pulp
The roller and the knob
The paper material that will be the outcome will be in A5 size, so it will act as a constraint for all the needed material and functions.
3D printer filament: 50+ grams
laser cutting material: since the project involves dealing with water, I would recommend using plexi glass instead of plywood since plywood would absorb the water, thus not sustainable
