Pottery Shards and Fish bones
Pottery shards are numerous, as many people still use pots for all purposes including cooking. The pottery shards generated as garbage are reaching the soils and adding great value.
Fish is the most common thing for every Bengali to eat. The numerious fish bones generated as waste is also added to the soils. Almost in every hotel non-veg is served, and eating non-veg is very common in Bangladesh, all the bones generated as garbage also gets added to the soil. The biochar and plus (bones / pottery shards / ash / compost / etc.) are adding great value to the soils. As the rainfall is high majority of soils in Bangladesh are acidic. The ash is adding value to the soils in increasing PH towards neutral. Ash is sprinkled on many plants as insecticide / to repel.

How do we make a Good stove which can burn these many types of biomass in use?
Traditiona l stoves in Bangladesh has large pot rest gaps, where heat and fire is lost, making the stoves less effective. The only reason for having such large gaps is for throwing in cow-dung balls, other loose biomass and sticks.
Many stoves are portable, seen here a women selling steamed food in a local shandy.

Floods are most common in many parts of Bangladesh, many houses are found standing over water, in such areas almost all the stoves are portable, made on baskets, old buckets, etc.
