\textbf{Abstract}
\begin{abstract}
\normalsize{
The study was conducted to document the experiences and to establish baseline information on the production of bio"=organic fertiliser using the Bio-Plus Activator in Biliran Province, Philippines. Within the span of two months, three batches of raw materials (\unitfrac[1]{ton}{batch}) were processed in the two production sites. Raw materials utilised included: batch 1- rice straw, goat manure, and carbonized rice hull; batch 2- rice straw, carabao manure, and carbonized rice hull; and batch 3- saw dust, chicken dung and carbonized rice hull.



	Using only manual labour, production activities (collection of raw materials up to bagging) requires 6 to 9 man"=days for every ton of raw material. The raw materials were processed inside a shed having a floor area of about 24 sq. meters. Decomposition period ranges from 22--27 days, while sweetening and curing lasted for 10 to 14 days. Raw material recovery ranges from \mbox{47.29\,\%} to \mbox{68.9\,\%}.



	The total N content of each of the three batches is comparable to that of the commercial organic fertiliser (1\%N, 5\%P, and 1\%K), so as with the total K content except for batch 2 which is a little bit lower. Total P content of each of the three batches were very low compared to the commercial organic fertiliser.



	Household level bio"=organic fertiliser production (1ton raw material/ month) is financially viable (NPV=4, 594.19, IRR=\mbox{28.73\,\%}, and BCR=1.03), but commercial production will yield higher financial benefit.



	Raw material sources available in Biliran, Philippines include rice straw, biodegradable kitchen wastes, sargassum species, saw dust and chicken dung. Farmers in Biliran have been using already organic fertiliser, which suggests that there is a growing demand of the product in the province.
