Due to various government regulations, bio-based 1,4-butanediol is gaining popularity among manufacturers and end-users. These companies are under increasing pressure to demonstrate improved environmental practices by reducing carbon emissions and increasing business sustainability. Novamont claims that bio-based BDOs can reduce greenhouse gas emissions by 60% across the entire lifecycle compared to fossil fuel-derived BDOs. Furthermore, calculations by Qore, a joint venture between Cargill and HELM, show that QIRA, a next-generation BDO made from plant-derived sugars, can reduce greenhouse gas (GHG) emissions by 93% compared to existing manufacturing methods. Countries worldwide are taking various approaches to enact and declare policies to reduce greenhouse gas emissions. These regulations encourage the use of 1,4-butanediol. The biomaterials industry is expanding.
The European Commission has issued several legislative recommendations, one of which calls for the European Union to become climate neutral by 2050, with an interim target of reducing greenhouse gas emissions by at least 55% compared to 2019 levels by 2030. This target represents a significant increase of at least 40% from the original target. The European Union has set a target of a 55% reduction by 2030, and this new proposal reinforces the commitment made in the European Green Deal to implement a comprehensive plan by that date. Furthermore, this initiative is aligned with the Paris Agreement's goal of limiting global temperature rise to 1.5°C and pursuing measures to keep it below 2°C.
Numerous bio-based 1,4-butanediol production facilities and related businesses were initially proposed or launched. However, to date, little development or information disclosure regarding its production has occurred. Many automotive parts and components, such as steering wheels, front and rear end components, bumpers, and connectors, are manufactured in the automotive industry using bio-based raw materials, including 1,4-butanediol derivatives such as PBT. The pandemic has had a significant impact on the automotive industry, reducing demand for various automotive parts and components made from bio-based BDO derivatives and hindering market expansion. In the electrical and electronics sector, bio-based 1,4-butanediol derivatives are used to manufacture lamp holders for home appliances, housings for home appliances, reset levers for circuit breakers, and other components. During this epidemic, sales of electrical and electronic products have decreased significantly, impacting investment in this industry. The current halt in industrial activity is also a result of labor shortages at manufacturing facilities caused by social exclusion and isolation.
Polybutylene terephthalate (PBT) is produced by polymerizing bio-derived 1,4-butanediol (PBT), primarily produced by carbohydrate fermentation, with terephthalic acid. PBT is a semi-crystalline, white or off-white thermoplastic polyester with improved electrical resistance, chemical resistance, and impact resistance. Industries such as electrical, electronics, communications, information technology (IT), and automotive industries can benefit from PBT's unique properties. Prior to this, DSM investigated and compared bio-derived 1,4-butanediol (BDO) produced using Genomatica's process technology with petrochemical-derived 1,4-butanediol (BDO) for PBT synthesis. The company evaluated polymerization based on several variables, including net polycondensation time (PC time) and polycondensation time (PC time).
No significant differences were observed between bio-derived BDO and conventional BDO in any polymerization parameters. PBT produced using bio-derived BDO manufactured with Genomatica technology ideally fell within the industry-defined parameter range. Furthermore, the variability of both petrochemical-derived and bio-derived BDO was within the range of typical measurement error. In addition, the experiments showed remarkable similarities in the enthalpy of fusion and heat of fusion of bio-derived and petrochemical-derived PBT.
The global bio-based 1,4-butanediol market is segmented by application and end-use industry.
Based on application , the global bio-based 1,4-butanediol market is divided into two categories: tetrahydrofuran (THF), polybutylene terephthalate (PBT), gamma butyrolactone (GBL), polyurethane (PU), and other applications.
The tetrahydrofuran (THF) segment has the highest market contribution and is estimated to have a compound annual growth rate (CAGR) of 30.39% during the forecast period. Chemical building blocks such as BDO and THF are used in the manufacture of a variety of industrial, commercial, and consumer materials, including engineering plastics, polyurethanes, biodegradable polyesters, spandex, and other specialty materials. Tetrahydrofuran is widely used in many industries as a solvent for organic compounds and as a raw material for polymer manufacturing. The conversion of THF used as a monomer in the manufacture of polytetramethylene ether glycol accounts for approximately 50% of the world's BDO. Bio-based 1,4-BDO accounts for only a small fraction of the total compared to 1,4-BDO produced by conventional methods. Several technologies are used in the production of tetrahydrofuran.
Tetrahydrofurans are typically produced by hydrogenating or dehydrating furan or 1,4-butanediol. The development of bio-based 1,4-BDO production technologies has made it possible to produce THF in an environmentally friendly process that emits bio-based 1,4-BDO. However, some companies, such as Shandong Landian Biotechnology, produce bio-based THF by chemically converting succinic acid (SA) . Inorganic acid catalysts such as sulfuric acid can be used to dehydrate 1,4-butanediol. However, this presents problems such as the hazards of inorganic acids and their corrosive effects on reactors. Tetrahydrofurans can be produced from 1,4-butanediol using various acid catalysts. For example, alumina catalysts, silica-alumina catalysts, alumina-supported tungsten oxide catalysts, and heteropoly acid catalysts can be used in the dehydration process of 1,4-butanediol.
In polyurethane manufacturing, 1,4-butanediol is frequently used as a chain extender. 1,4-butanediol offers an excellent balance of hardness and flexibility at low temperatures. Compared to other diols, 1,4-butanediol excels in reactivity, linearity, and overall system compatibility. Polyurethane cast elastomers are mass-produced using 1,4-butanediol. The diverse physical properties of polyurethane make it suitable for numerous applications, including flexible and rigid foams, varnishes and coatings, adhesives, electropotting compounds, and fibers such as spandex and PUL. It is a material of choice for a wide range of end-user applications, including freezers and refrigerators, building insulation, furniture and mattress fillings, automotive parts, coatings, adhesives, rollers, tires, composite wood panels, shoe soles, and sportswear. Due to its increasing use as insulation, the PU foam segment is expected to expand significantly during the forecast period.
