DIY Stackable Compost Bin

    Since I do not have enough space outside my HDB flat, mainly corridor or stairways, to increase compost bin capacity, meaning adding more compost bins, I decided to think of DIY stackable compost bin design for my needs. 

    I found a worthwhile Youtube video on this: 

    The design for the stackable compost bin is the closest of what I was thinking of using. This design just drills holes within 2 inches away from each other and only at the sides and top. No holes are drilled at the bottom of the bin. Even though there might be liquid coming out from the bins, that is another problem I need to solve but at least it gives me a head-start. 

    The stackable bins that I am planning to use are the Redmart (Red) or NTUC online (Blue) logistic containers, looking similar to the picture below.

    This type of containers are usually have depth so more compost materials can be added per bin and the materials is thicker compared to normal plastic containers. Such industrial stackable and nestable plastic storage container box are sometimes thrown away after grocery deliveries and it is possible to find them during dumpster diving once in a while. Since the Redmart and NTUC online are slightly different in size (NTUC being slightly bigger), I have not decided which one to use but I have an existing Redmart container outside my HDB flat for me to use straight away. I would likely start off with that Redmart container outside my HDB flat first. I kept a few NTUC containers in my study room and if needed, I might use them instead of looking for new ones.

    Another type of container is the new Redmart containers which is stackable and without the lids. This might provide more airflow but the depth is about three quarters of the above containers. For these container, I may need more containers to compost the same amount of compost materials. Another consideration is with bigger airflow, it might also attract flying insects or lizards coming into these containers. Others include losing moisture so I may need to add water more often compared to the earlier container. Maybe I just try both and see how it goes since I have one outside my HDB flat as well.

    I am still unsure how far I want to take this composting hobby and how long my enthusiasm will last. But at least for a while since I am farming for edibles.
