RCB (Lump Form): Contains 85–95% pure carbon, leading to superior heat generation and combustion efficiency.
Charcoal: Typically contains 60–80% carbon, resulting in comparatively lower thermal output.

RCB (Lump): Offers a calorific value of 7000–8500 kcal/kg, making it highly efficient for high-temperature industrial processes.
Charcoal: Has a lower calorific value (5000–7000 kcal/kg), making it less energy-dense.

RCB (Lump): Denser structure leads to a slower, more sustained burn, allowing better control in furnaces and longer heat retention.
Charcoal: Burns faster due to its porous structure, often requiring frequent feeding and causing heat fluctuation.

RCB (Lump): Ideal for steel re-rolling mills, billet/rebar production, cement kilns, and high-heat industrial boilers due to consistent heat release and low volatility.
Charcoal: More suitable for low to medium temperature uses such as cooking, artisanal furnaces, or traditional kilns.

RCB (Lump): Promotes circular economy by recycling tyre waste and reducing landfill and pollution.
Charcoal: Can contribute to deforestation and biodiversity loss if biomass sourcing is not sustainable.

RCB (Lump): Though it may contain moderate sulphur and higher ash, emissions can be controlled with filters. The ash is often rich in metals like zinc and iron, which can be recovered.
Charcoal: Emits higher volatile organic compounds (VOCs) and contributes more to air pollution if used in large-scale setups without emission controls.

RCB (Lump): Offers higher energy output per kg, making it more cost-effective over time in large-scale industrial use.
Charcoal: Though sometimes cheaper upfront, it requires more volume to achieve the same energy output, increasing total consumption.
