Concentration of waste, which is difficult to use at small facilities, etc., through expansion of waste treatment areas and effective use of energy, etc.
As waste amounts are small in municipalities, etc., with small populations and treatment facilities are small in size, it is difficult to use waste for efficient recovery of heat and power generation, etc. On the other hand, when waste is collected and treated in large-sized facilities, higher efficient heat recovery rates can be realized and electricity can be sold. It is the transportation of waste that becomes a challenge in the case of expansion of treatment. However, by making RDF, moisture is reduced and weight is about 1/2 and volume is about 1/5 ~ 1/7 and as it has no odor and can be stored for long periods of time, and concentration costs can be reduced.
Efficient recovery and effective use of unused waste energy
By making RDF, as continuous stable incineration can be performed at high temperatures, heat energy from incineration can be recovered at a high rate of efficiency and power can be generated. The Fukuyama Recycling Power Plant operates at a power generating efficiency of 28.1%, which is much higher than that of ordinary waste incineration facilities having power generation facilities.
Reduction in carbon dioxide by using unused waste energy for power generation
When using heat (renewable energy) generated in connection with incineration of waste and highly efficient power generation is performed, electricity can be sold to other facilities, etc. As power generation by thermal power plants is not required to generate the same amount of electricity generated by incineration, use of fossil fuels such as coal can be constrained and carbon dioxide emissions can be reduced by that amount.
Reduction in final disposal amounts by turning incinerated ash into melted slag
Incinerated ash is typically landfilled at final disposal sites, but in the case where ash is turned into melted slag, this conversion can be effectively used as civil engineering materials, etc., and the life of final disposal sites can be extended.
Promotion of zero emissions by recovery of energy, effective use of slag, metals and reuse of discharged water, etc.
Fukuyama Recycling Power Plant incinerates RDF waste, sells thermal energy as electricity and collects incinerated ash as melted slag and metals and sells these resources. Water discharged from the facilities is reused, etc., to realize resource recycling society by zero emissions.
Reduction in environmental loads by dioxins, etc., through stable continuous incineration at high temperatures
By making RDF, it is possible to stably incinerate waste with less moisture at high temperatures. This is useful for not only energy recovery but also for detoxification of hazardous substances and constraining generation of dioxins, etc.
Cost reductions in waste treatment by effective use of recovered energy, slag and metals
Through expansion of RDF, as unused waste energy is efficiently recovered, power is generated and incinerated ash can be recovered and sold as melted slag and metals, total costs required for waste treatment can be reduced.
