Hi Jonathan,
Common agricultural by-products include:
– Coffee husks
– Rice husks/hulls
– Coconut shells and wastage
– Banana leaves and peels
– Wastewater associated with crop production can also be considered
Additionally, I recommend researching crops that are commonly grown in Timor-Leste’s climate and the byproducts that may be associated with them.
Non-organic by-products include predominantly single-use plastic from imported packaged goods.
I hope this helps.
Kind regards,
Evelyn
