Hay Drying
B41 Agrotech Sdn Bhd constantly strives to achieve efficiencies and develop new opportunities, by identifying synergy between related processes and their inputs and outputs. The oil palm produces a lot more biomass than just fruit bunches. We have already proven the fronds to be safe and valuable as a roughage cattle feed. The plantation also grows other useful feed plants including various grasses, the leguminous ground cover mucuna, and wild or cultivated tapioca. Unfortunately these resources mostly go to waste because of their seasonal availability and the limited capacity to use them at the time. In order to fully utilise them within the plantation ecosystem, and even better to utilise them outside the confines of SPAD plantations - ie as saleable commodities - they need to be dried and packaged for convenient storage and transport. They need a significant input of energy to reduce their water content. On the one hand we have great feed resources going to waste for lack of drying, and on the other hand we have a lot of energy going to waste in the palm oil mill. Let's put these resources together and capture their value by making a commercial product.
The problem of poor animal production in the very presence of wasted feed resources is found throughout Malaysia. Wouldn't it be great if the SPAD and B41 Agrotech team could be the first in Malaysia to solve the problem ! Malaysia's capacity for animal production will escalate dramatically.
SPAD has indicated that they are considering the potential for a palm frond pelletising factory (OPF pellets). Our proposal for a hay drying plant will be a first step in this direction, but without the million dollar price tag associated with it. In fact, we believe that the further step to a pelletising plant will be totally un-necessary, because the demand for baled hay in Malaysia will be greater than the export potential for OPF pellets. As a first step, we have invited Mr Singh, the Batu Niah Mill manager, to begin considering designs and costs of a general purpose biomass dryer in the mill.
Biogas, Woodgas & Charcoal
SPAD has indicated an interest in producing Biogas from feedlot manure. This is indeed an excellent idea, but is it any better than using the manure for compost or worm farming ? To answer this question we need further research, and to this end a trip to Indonesia (Pontianak and/or Surabaya) is required. We need to view the systems already operating there, especially to study the gas capture, storage and utilisation procedures and equipment.
However, once again seeking synergies, we may find an even better resource at our fingertips, again in the huge amount of biomass produced from the oil palm tree. The EFB, press fibre and kernel shells from the mills, the pruned fronds in the plantation, and bare leaf stalks from the feedlot, could all be converted to woodgas, producing enough energy to power a town the size of Batu Niah itself. If not fully gasified, they could be partly gasified, yielding another by-product in the form of charcoal. Partial gasification and charcoal production is a lower level technology, which can share the gas capture and storage systems of biogas production.
We have produced charcoal from palm leaf stalks to prove it can be easily done. Charcoal has a base value as a soil conditioner, returning carbon and minerals to the soil in a lower volume than the alternative mulch or compost. With marketing efforts, higher values for "activated" charcoal or charcoal briquettes could be achieved, and there may even be opportunity to sell "carbon credits" when charcoal is returned to the soil as a means of carbon sequestration.
Together, SPAD and B41 Agrotech could become Malaysia's leader in the practical application of Biomass Energy Technologies. This is very relevant now, after the recent Copenhagen Conference.
