3D Concrete Printing Technology in Affordable Housing

ЁЯФ╣ Why in News & Recent Development

The Andhra Pradesh government is set to deploy 3D Concrete Printing (3DCP) technology to construct residential houses for beneficiaries under the Pradhan Mantri Awas Yojana-Gramin (PMAY-G) scheme. This marks a paradigm shift from conventional masonry towards automated construction methodologies in public welfare housing.

ЁЯФ╣ Key Conceptual & Analytical Details

3D Concrete Printing is an advanced form of construction-scale additive manufacturing where a computer-controlled robotic printer directly translates digital Building Information Modelling (BIM) designs into physical structures. It operates by extruding specially formulated cementitious materials through a nozzle in successive horizontal layers. The technique heavily relies on advanced material science and automation to ensure that the wet mix maintains precise extrudability, buildability, and rapid setting times without collapsing under its own weight.

ЁЯФ╣ Strategic Importance & Future Impact

The primary benefits include unprecedented construction speed, substantial reduction in material waste, and the elimination of traditional timber or steel formwork. Furthermore, the development of low-carbon inks and material reuse frameworks is crucial to mitigate the environmental footprints associated with increased cement consumption. In India, this technology holds immense potential for affordable housing missions, disaster-relief shelters, remote-area deployments, defense fortifications, and rapidly erected public facilities.

Jawahar Dweep Marine Oil Terminal

ЁЯФ╣ Why in News & Recent Development

The Jawahar Dweep Marine Oil Terminal has been officially declared plastic-free by the Mumbai Port Authority, securing the distinction of becoming the first oil terminal in India to completely eliminate single-use plastics across its operational expanse.

ЁЯФ╣ Key Conceptual & Analytical Details

Jawahar Dweep, historically known as Butcher Island, is a restricted island situated off the coast of Mumbai, Maharashtra, located approximately 8.25 kilometers from the Gateway of India. Most of the island is covered with thick vegetation, featuring a prominent hillock rising from its center. Functioning as one of Mumbai Port's primary marine oil terminals, it handles bulk crude oil and petroleum products across its five active jetties, supported by fully automated systems for liquid bulk handling.

ЁЯФ╣ Strategic Importance & Future Impact

Crude oil unloaded at Jawahar Dweep is safely stored in massive oil containers on the island before being transported via dedicated underwater and land pipelines to Wadala in Mumbai for downstream refining. Achieving a single-use plastic-free status sets an exceptional environmental benchmark for critical maritime industrial infrastructure and heavy port logistics across the country.

Coppersmith Barbet: Rare Color Variant Sighting

ЁЯФ╣ Why in News & Recent Development

A rare colour variant of the Coppersmith Barbet, a commonly seen green bird across the Indian subcontinent, has been recently photographed on the outskirts of Hyderabad, generating immense interest among ornithologists and wildlife conservationists.

ЁЯФ╣ Key Conceptual & Analytical Details

The Coppersmith barbet (scientific name: Psilopogon haemacephalus), also known as the crimson-breasted barbet, is a small, brightly coloured Asian bird belonging to the barbet family (Megalaimidae). It is distinctly recognized by its repetitive, metronomic call that sounds strikingly similar to a coppersmith striking metal with a hammer. Morphologically, it features a black-bordered yellow face, a red forecrown, and a red throat patch, with upper parts in grass green and underparts in yellowish-green streaked with darker green.

ЁЯФ╣ Strategic Importance & Future Impact

As resident birds across the Indian subcontinent and Southeast Asia, they typically inhabit gardens, groves, and sparse woodlands, carving out nesting holes inside trees. Their stable ecological presence across varying terrains makes them vital indicators of urban and rural arboreal health.

Rashtriya Vayoshri Yojana (RVY)

ЁЯФ╣ Why in News & Recent Development

The Union Ministry of Social Justice and Empowerment recently distributed 662 essential aids and assistive devices valued at over тВ╣10 lakh to senior citizens under the flagship Rashtriya Vayoshri Yojana (RVY), reinforcing the central government's commitment to geriatric welfare.

ЁЯФ╣ Key Conceptual & Analytical Details

Launched in 2017, the Rashtriya Vayoshri Yojana is a Central Sector Scheme fully funded by the Central Government. It is specifically designed to provide free assisted-living devices to senior citizens belonging to the Below Poverty Line (BPL) category whose monthly income does not exceed тВ╣15,000, with a specific focus on senior citizens aged 80 years or older receiving devices directly at their doorstep.

ЁЯФ╣ Strategic Importance & Future Impact

Eligible elderly beneficiaries receive specialized physical aids such as walking sticks, wheelchairs, hearing aids, spectacles, artificial dentures, and crutches based on assessed medical needs. The financial expenditure for implementing the scheme is drawn directly from the Senior Citizens' Welfare Fund, while execution is spearheaded by the Artificial Limbs Manufacturing Corporation (ALIMCO).
