Graphene Nanotubes Cut CO₂ in Conductive Materials

25 Apr 2026 CW Team

OCSiAl reports that replacing conventional conductive fillers with graphene nanotubes can reduce CO₂ emissions in conductive materials by up to 26 per cent, addressing a key sustainability challenge in material manufacturing.

Conductive polymers, widely used across electronics, automotive, healthcare, and industrial applications, typically generate significantly higher emissions than non-conductive materials. This is due to high loading requirements of traditional additives such as carbon black and multi-walled carbon nanotubes, along with energy-intensive processing and logistics.

Graphene nanotubes require only minimal dosage—often a fraction of a per cent—enabling more efficient material use and lower overall emissions. Depending on the application and polymer system, emission reductions can range from at least 5 per cent to as high as 26 per cent.

The findings are based on a Life Cycle Assessment conducted in line with ISO 14040/14044 standards, covering raw materials, transportation, processing, and waste across multiple sectors including construction, automotive, and energy.

The development reflects a broader shift towards advanced materials that combine performance with measurable decarbonisation impact, as industries move from sustainability commitments to implementation.

ABS Marine Sees CRISIL Credit Rating Upgrade

ABS Marine Services has secured an upgrade to its long term and short term credit ratings from CRISIL, reflecting improved profitability and revenue growth through long term contracts. CRISIL moved the long term rating from BBB+/Stable to A-/Stable and revised the short term rating from A2 to A2+. The action signals strengthened financial metrics and operational resilience. The company benefited from durable client relationships with firms such as ONGC and Schlumberger. The rating decision followed stronger cash flows and an enlarged bank loan facility, which increased from Rs 3,705 million (m..

Project BRAHMANK Marks 16 Years Of Strategic Roads In Arunachal

Project BRAHMANK is marking 16 years of work to establish strategic road and bridge links across Arunachal Pradesh, maintaining and developing 811 kilometres of roads and nearly 86 bridges that range from small culverts to large steel and arch bridges. These transport links are described as critical for ensuring year-round movement of defence personnel, equipment and essential supplies while improving everyday travel for people in remote villages. The project balances national security requirements with regional development by focusing on reliable access in challenging terrain. Notable enginee..

Longleng CSOs Give One Week Ultimatum Over Two-Lane Highway

Civil society organisations (CSOs) in Longleng district have demanded immediate restoration of the deteriorating Changtongya–Longleng two-lane road and sought a detailed status report on the stalled construction within one week. The demand followed a consultative meeting convened under the Phom Peoples' Council (PPC) to discuss welfare and development concerns. PPC president YB Angam Phom said prolonged non-maintenance had caused hardship to commuters and affected transportation, local commerce and the district's development. The meeting urged authorities to undertake immediate restoration a..
