Calculate Embedded Emissions for Unwrought Aluminium (HS7601)

Enter your input

Payable emissions (tCO₂e/t)

Total CBAM Cost (€)

Notes:
There may be a difference when calculating the price with respect to import volume, carbon price, and benchmark emissions, as the embedded formula may result in minor variations due to decimal rounding. Therefore, the actual value may vary.

CBAM is applicable to trade volumes starting from 50 metric tonnes. For trade volumes below 50 metric tonnes, CBAM does not apply.

Usage Procedure – How to use the CBAM Calculator Sheet

Enter or update values only in the INPUT
PARAMETERS section (Highlighted in blue) , including
the carbon price, benchmark emissions, CBAM
chargeable percentage (as per the phase-in year),
and imported quantity.

The system will automatically calculate the payable
emissions and the total CBAM cost (€) based on the
inputs provided.

Notes:
• Change any input value to automatically update CBAM cost.
• Formula used: Carbon price × payable emissions × quantity.
• Model aligned with CBAM supplier-side illustrative methodology.

JNARDDC develops process to convert CFA into aluminium fluoride and high purity silica

EDITED BY : DEBANJALI SENGUPTA 2MINS READ

Jawaharlal Nehru Aluminium Research Development and Design Centre (JNARDDC), Nagpur has reportedly innovated a process to convert coal fly ash into useful products such as aluminium fluoride and high purity silica at laboratory scale.

So, now the current demand of aluminium fluoride, which is about 42,000 tonnes in Indian aluminium smelters, can be fulfilled by coal fly ash alone. This will help in saving natural resources, such as bauxite and sand, and lead to proper utilisation of coal fly ash. Aluminium fluoride is majorly used in the primary aluminium industry during the production of aluminium from alumina.

The coal fly ash (CFA) generation in India is about 200 million tonnes per annum containing 30 per cent alumina and 60 per cent silica.

The innovation of the process was based on 10 gram of CFA, which was interesting and promising, and prompted to submit a proposal to Ministry of Mines to set up a bench scale conversion facility.

CFA is one of the solid wastes generated in thermal power plants during the process of power generation. According to 2017 data, power generation by coal-based thermal power plants in India was about 218 Gwh that resulted in 195-200 million tonnes per annum of CFA generation.

A team of JNARDDC is working on its parameters, recycling of solvent, environmental sustenance and cost economy of the process under the guidance of institute director Dr. Anupam Agnihotri.
