Description : | CSIR-Advanced Materials and Processes Research Institute (CSIR-AMPRI), Bhopal has developed a technology for making Evergreen Hybrid Ply and Composite Wood, using Parali (agro waste) and industrial waste particulates / fibres. This technology was developed with multiple objectives for multifunctional application as well as in view of effective use of Parali (agro wastes) and industrial wastes such ash marble wastes and fly ash. The findings of the research paves ways to introduce new materials to the society contributing to the National Forest Policy of Ministry of Environment and Forest (MoEF), Government of India for development of wood substitute for building application so that consumption of timber in building and house construction can be minimised. Furthermore, this will be a potential solution for effective utilisation of different agro-industrial wastes such as paddy straw, wheat straw, marble wastes, red mud, fly ash and other mineral, metallurgical wastes leading to solves various environmental threats associated with management of agro industrial wastes, deforestation and ecological imbalance.
For making Evergreen Hybrid Ply and Composite Wood, agro wastes primarily Parali (paddy straw/ stubble) and wheat straw, and industrial wastes, mainly marble wastes, fly ash from Thermal power plants, red mud from Aluminium industries were used as a primary raw material with natural fibres in polymeric system (Polyester / epoxy resin). The approach and concept for making this Evergreen Hybrid Ply and Composite Wood is unique and have not yet been developed universally for practical commercial utility both in developed and developing countries. Two international patents have been recently granted each in Eighty Countries on this technology.
The performance of Evergreen Hybrid Ply and Composite Wood would vary depending on the raw materials quantity, quality, particulate- fibre ratio, particulate / fibres – binder ratio, type of polymeric system and processing and manufacturing conditions. Evergreen Hybrid Ply and Composite Wood can be made in single stage fabrication process as solid material as well as two stage process as sandwich composite of required performance. The demonstrated results revealed that high quality and glossy finish composites under single stage operating condition can be achieved using about 60% agro-industrial wastes. The innovative composite materials have variety of application potential for infrastructure in construction sector, locomotive (train) and other transport system (Bus, ship etc.) and infrastructure as doors, false ceilings, flooring, architectural wall panels, partition and furniture etc. The Evergreen Hybrid Ply and Composite Wood is stronger, environmental friendly. Addition of agro-industrial wastes particulates and fibres enhances the surface finish, density, flexural modulus and resistance to abrasion. The Evergreen Hybrid Ply and Composite Wood are durable, resistance to weather, corrosion, water, moisture and is termite, and fungus free composites. The composite materials are fire retardant, self-extinguishing nature, cost effective and maintenance free materials. Evergreen Hybrid Ply and Composite Wood has potential to use as an alternate material for wood / timber, plastic, synthetic wood such as MDF Board, particle board and ply wood and all other conventional materials used in furniture industry.
The technology is ready for commercialisation. A technology document has been prepared which would be delivered to the licensee. This technology document describes about the process know how for manufacturing Evergreen Hybrid Ply and Composite Wood, which includes the details / specifications of raw materials such as (i) different agro-industrials wastes, fibres, particulates and polymeric system (ii) casting, fabrication of composites and curing (iii) performance of Evergreen Hybrid Ply and Composite Wood, (iv) requirement of primary equipment and machineries for manufacturing of Evergreen Hybrid Ply and Composite Wood in commercial scale.
This technology would provide holistic solution to stop Parali burning and contribute for Atmanirbhar Bharat in creatingemployment and income and improving the livelihood of farmers and rural people in the state of Haryana and Punjab, where huge quantity of Parali has been burned which creates major smog and air pollution to the National Capital Delhi and NCR. This technology is o ne of the country most wanted innovation at this juncture as a game changer technology to provide multidisciplinary solutions to address multiple problems and contributing to National Program on Make in India, Skill and Clean India Mission program leading to job creation and environmental safety.
For this technology two International Patents namely (i) A glossy finish sandwich composite and process for preparing the same (Grant No. 201811047389 , WO 2020/121319 A1, 18 June, 2020) and (ii) High performance glossy finish green hybrid composites with variable density and an improved process for making thereof (Publication No: 201811016873. WO2019/211862A1)have been filed and granted.
In pursuance of the license agreement with M/s. Shubh Green Sheet Pvt Ltd, Bhilai, CG, on the Primary know-howto Mr. Arun Kumar Sahu and his collegium partner Mr. Ashok Kumar Verma, training and satisfactory demonstration for manufacturing Evergreen Hybrid Composites of Parali (Agro Wastes) and Industrial Wastes (Evergreen Hybrid Ply and Composite Wood) have been given to seven of his officials at CSIR AMPRI Bhopal during 16-21 October 2020 and the officials / trainees are fully satisfied with the working of the process and the know-how given to them. Mr. Arun Kumar Sahu, the CEO M/s. Shubh Green Sheet and his officials have showed confidence in this technology and conveyed that they will soon to setup industry in Bhilai, CG for commercial production. |
