“…These emissions vary depending on the distance from plantation to plant and the type of biomass processing as the processes of drying, pelletization, and torrefaction may dramatically increase the emissions associated with bioenergy. A study on the island of Flores found that pellet processing accounted for nearly 60% of total emissions from the production and combustion of sorghum pellets 48,49 . The capital investment required to expand pellet production potential, expand torrefaction or RDF production, or retro t coal plants for optimized co-ring may disincentivize retirement of coal plants, further extending the life of coal plants and offsetting any emissions reductions made by substituting coal with biomass 31,49,50 .…”

Reducing emissions in Indonesia’s energy sector requires mitigating coal plant emissions while avoiding land use change emissions. Given Indonesia’s abundant biomass resources, co-firing biomass presents an opportunity to reduce carbon emissions using agricultural residues, forestry waste, and municipal waste. We investigate whether available biomass waste is sufficient to meet feedstock requirements for co-firing at a range of ratios, whether demand can be met throughout the year and across the archipelago, and resulting emissions reductions. We conducted a feasibility study for each captive and non-captive coal plant in Indonesia, evaluating suitable biomass waste feedstocks including wood (both forest residues and industrial by-products), rubber, sugarcane, oil palm (kernel shell and empty fruit bunches), rice husk and straw, and municipal solid waste. Our results indicate that incorporating biomass waste into coal plants can reduce carbon emissions and contribute to the country's renewable energy targets without additional deforestation. However, while existing biomass waste is sufficient to meet co-firing demand at low ratios, competition with alternative uses and limited biomass supply in eastern provinces, where coal capacity is growing, preclude meeting demand at higher ratios. Our study provides insights into seasonal and spatial waste availability across Indonesia, and potential land use impacts and emissions reductions.

“…Thermal energy content values between 3-25 MJ/kg are reported for different ISS. [15][16][17][18] The calorific value expresses the energy content of the solid phase in the sludge. The sludge to be disposed of is generally dewatered and contains approximately 15-30% solids by mass.…”

“…The analysis involved proximate, ultimate, and ash element tests. The results showed that when sludge (20%) is mixed with bottom ash(40%) and biomass(40%) it can be a substitute fuel instead of coal 16 Kliopova et al investigated the possibility of producing solid recovered fuel (SRF) using composted and screened (10-40 mm) SS and biomass waste. In the study, it was stated that the materials intended to be used as fuel contain lower humidity and higher C ratio after composting.…”

Industrial sludge must be disposed of by incineration or storage methods. It is possible to produce energy by incinerating the sludge after drying. However, some sludges cannot be incinerated due to their low calorific value and/or high pollutant load. In this study, a novel process in which sludges with high calorific value and other sludges are mixed, dried and processed to produce solid fuel without using any additives is described. A technical and economic model of the process was established and feasibility analysis was carried out for different capacities. According to the results of the study, with the increase in capacity, the cost for the unit capacity and the return for the unit capacity increase. Most of the plant's income comes from waste disposal. When the investment is made with equity, the payback period is shorter than 2 years for wet feeding capacities of 1 ton/h and above. The cost of the investment increases more than 2 times when 50% of the investment cost is supplied by a bank loan. In this case, the payback period is also increasing. In order for the profitability of the facility to be sustainable, the composition and amounts of sludge produced in the region should be analysed. In this study, it is assumed that the types and amounts of waste that will come to the facility are capable of filling the facility's capacity and providing the required calorific value standards.
