Insight Statement

💡
Kids needs a way to compost because they can have fun while contributing to the refugee community.

Study on Precedents

The article introduced Bokashi Kitchen compost, a small bucket that could be placed in kitchen for composting. Activator is added after filling in compost material.
The blog introduced a project aimed to improve sanitation by reducing household garbage in refugee camps
A video of a compost enthusiast comparing 12 composters of different designs. Takeaway: horizontal rotation is better than vertical rotation. Ease of rotation is very important. Barrel has to be really sturdy. Handles fall off easily.

Waste management & Composting - Barrel composting, push the Topic free fertilizer waste is not as important for the recipient, understand culture s Relations to bad smell and deal with it, also look into farming Bugs from composting for Money or Food.

What are the food routines in the camp like? How will you integrate composting into the daily life?

Check out this reference regarding faster composting and biogas production: https://phys.org/news/2016-09-illinois-tech-scientists-aquaponics-farm.html There is definitely a need for that, making people understand of the processes is key.

To consider the implementation and how user's awareness.

It is interesting to be a playing device as well.

Good to think about incentive and education impact.

Good to think about the recyclable materials, and how to make the whole composting project more interesting and playful.

Concern about the education, because they currently always mix up organic and inorganic waste inside the camp

Source: Mike Zukerman, 2020/09/25 Session at HKU

Currently have human waste management plant, can think of how to integrate with.

Mentorship session with Cesar

Great prototyping! Low tech is awesome

Usage ? Type of food that go inside? ? Mixing the existing soil

Testing ? Start to store food Use scientific Method and make several samples with different waste makeup and observe over time

Context ? City, neighborhood? Wheels on ... mud? ? Social Structure, who would use it? ? Who owns it? ? Economic Model? ? Adding human faces?

Comments from Moury Rahman and Saiba Sahira
Really worth investigating as the existing waste management is less successful.
On VOLUME - They produce huge amount of waste, 10% of it is totally non-recyclable, 60% organic waste.
💡
Comment from Gisa Zippert: Where did you get this information? If they eat sometimes only rice and little vegetable how can a family produce 12 kg of waste? Is the amount of waste you mentioned produced in a day or a year?
On CURRENT WASTE MANAGEMENT- 2 Bins, red(inorganic) not and green(organic). There is a specific person to collect the waste. How our design position itself in the existing mechanism?
SPECIFICITY- Will the separation of waste too difficult to be understood? With practicality in mind, we are planning to narrow down the "waste recycled" from all food waste to 1-2 food. (say something which is a common in daily diet of Rohingyas). This ensure a manageable amount of food waste that can be efficiently composted. This can be considered as a pilot scheme to nurture the habit of composting which possibly can extend to more types of food waste

The Making: Prototype 2

(21/10/2020)

Updates

  • Reaching out for similar projects as precedents to learn from with the help from Cesar
Compost City/ A economical sustainable initiative of promoting composting in Cambodia
Pimp my Carroca/ An art project upgrading the recycle workers image through graffiti works on their carts
  • Starting discussion with our Rohingyan buddy(Arfat) to understand their habits, in particular the food culture and waste management.
Food preferrence of Rohingya People (according to ICCO)
Food preferrence of Rohingya People (according to ICCO)

Improving on our previous prototype

  • Larger container(32L) to prototype the actual household size
  • Improving the openings by adding hinges and locks
  • Focusing on heat and ventilation after hearing the advice from a friend who has experience in doing compost at home
  • Putting in food waste(limiting ourselves with vegetable scraps and egg shells) with some soil which serves as accelerator for the process

The Testing: Prototype 2 (30/10/2020)

We are placing the compost bin in the Rooftop Farm in HKU (edible space) with the generous help from Yuki Chan.

Meeting Session with Monorom, from Compost City Cambodia (2/11)

image

Draft on 19/11

Notes and feedbacks.

  • Compost City is a economically-sustainable initiative of promoting composting in Cambodia. Starting from homemade DIY boxes, Monorom kickstarted her project and has since attracted many citizens in Phnom Penh to begin composting.
  • started with a business competition, then modified as the first prototype is highly personalized thus expensive
  • second prototype includes: a kit of manual, 2 bins, tools
  • problem of the Compost Bin now: wobbling< turning< plastic deteriorate under sun. how to educate/ sustain.... waste: two composting bin, let the first one rest and avoid keep adding new organic matters daily. as easy as possible time consuming and poor drainage
  • how to empower compost collector
  1. interview e.g. fb vid
  2. start with equipment they use
  3. branding/ uniform

Necessary Instruments and Instructions

Instruments

  1. Label the compost bin. (magic tape, what can be recycled)
  2. any tray —removable tray for fertiliser
  3. paper bag to transport food waste to compost bin

Instructions

  1. Prepare Food
  2. Extract the appropriate food waste (egg shell, potato skin, )
  3. transfer the waste to the bin
  4. Putting in food waste(limiting ourselves with vegetable scraps and egg shells) with some soil which serves as accelerator for the process

Research on material available on site

Demand for composting?

→ making it to children playground

→ similar to the turnaround (to get water) (failed because it is too hard for the kids to turn)

Enough profitable returns?
