Making the Decision
Choosing an engineering branch can be challenging, with so many options. It gets even harder when two branches are very similar and overlap. This makes it difficult to decide which one to pursue.
Imagine you're trying to choose between two sports: soccer and futsal. Both involve a ball and similar skills, but soccer is played on a larger field with more players, while futsal is played indoors on a smaller court with fewer players. The similarities and overlap between the two sports make it hard to decide which one to pick.
Today, we are looking at two closely related branches: "Chemical Engineering" and "Biochemical Engineering." We will explore what they study, their use, their applications, the industries that use them, available programs, the best colleges in India, and job opportunities.
Who is a Biochemical Engineer?
Imagine someone is sick and needs medicine to get better. Some medicines are made using tiny living things called bacteria or cells. These tiny helpers can produce important ingredients for the medicine.
A biochemical engineer knows how to use these bacteria or cells to make the medicine. They figure out the best way to grow the bacteria or cells and help them produce the medicine ingredients. The engineer ensures everything is done safely and correctly so the medicine works well and is safe to use.
Biochemical Engineering uses chemical engineering methods for industries that work with biological materials, like cells or parts of cells. For instance, it uses microbes and enzymes to make useful chemicals such as antibiotics. This field studies how cells work inside a reactor.
Employment Areas for Biochemical Engineers
Biomedical engineers work on new technology and medical advances to create devices and equipment that improve human health. For instance, they might develop software for medical machines or create computer models to test new medicines.
Biochemical engineers study different biological materials to create products like plastics, oils, paints, detergents, medicines, agricultural chemicals, and foods for people to use.
These workers deal with recycling, waste disposal, controlling water and air pollution, and public health problems. Environmental engineers also study and work to reduce the impact of acid rain, global warming, car emissions, and ozone layer depletion.
Biochemical engineers mainly work on creating systems to improve how food is produced, processed, packaged, stored, and distributed.
They work in laboratories, which can be either corporate or part of a research institution. They might work as metabolic engineers, using molecular genetics to enhance the production of metabolites and proteins. Others work as enzyme engineers, making chemicals and biochemicals using biocatalysts.
Bioengineering is a field that combines different areas of study and holds great promise for cancer research. It will help create new tools for diagnosing cancer, new ways to deliver drugs, and advanced techniques for growing tissues both inside the body (in vivo) and in the lab (in vitro).
Biological engineers work in chemical manufacturing, researching to make biomass conversion more efficient and cost-effective. They use microbial physiology, fermentation, enzymatic hydrolysis systems, process monitoring and control, thermochemical processes, and catalytic cracking to achieve this.
They work in labs that can be corporate or part of a research institution. Some might be metabolic engineers, using molecular genetics to boost the production of metabolites and proteins. Others might be enzyme engineers, creating chemicals and biochemicals using biocatalysts.
Scope and Salary of Biochemical Engineer
Fresh graduates in Biochemical Engineering can begin their careers with salaries ranging from INR 3,00,000 to 5,00,000 annually. As they progress in their careers and attain senior-level positions, professionals in this field can earn between INR 15,00,000 to 20,00,000 annually. The scope for biochemical engineering offers promising growth opportunities in various industries.
Chemical Engineering
Who is a Chemical Engineer?
A chemical engineer is like a chef in a kitchen who mixes different ingredients to make yummy food. But a chemical engineer mixes chemicals instead of food to make useful stuff like medicine, shampoo, or even car fuel! They use their knowledge to figure out the best ways to make these things safely and efficiently, just like a chef follows a recipe to make a delicious meal.
Chemical Engineering is a field that focuses on designing and managing factories where chemicals and other products are made from raw materials through chemical processes. It involves creating and operating industrial plants that produce various substances we use daily.
Employment Areas For Chemical Engineering
Chemical engineers work on various parts of plant design and operation. This includes safety checks, process design and analysis, modelling, control engineering, chemical reaction engineering, nuclear engineering, biological engineering, writing construction specifications, and creating operating instructions.
In the textile industry, chemical engineering is key in designing and creating new textile products that follow the latest fashion trends while being functional and affordable. As lifestyles change around the world, there is also a need to develop innovative textiles.
Chemical engineers in the minerals industry design, develop and manage processes to convert and refine raw materials into finished products.
Chemical engineers play a crucial role in manufacturing organic products like polymer fibres, films, coatings, textiles, cellulose, paper, dyes, explosives, rubber, rocket propellants, solvents, plastics, agricultural chemicals, pharmaceuticals, coal-based fuels, and petrochemicals.
Preparing plans that illustrate the layout of plant equipment for manufacturing fertilisers. Designing, overseeing, and installing different chemical plants, equipment, and machinery.
The primary role of chemical engineers is to design and solve problems in processes that produce chemicals, fuels, foods, pharmaceuticals, and biological products, among others. They typically work in large manufacturing plants to optimise productivity and ensure high product quality while keeping costs low.
Chemical engineers contribute to developing steel processes and products in steel mills. They may work in testing labs, conducting chemical analyses of steel. They also analyse reactions involving slag.

The scope and salary of B.Tech Chemical Engineering jobs depend on job title, experience, location, company, industry, and more.
Contrasting Biochemical Engineering and Chemical Engineering
Biochemical and Chemical Engineering are parts of chemistry with many similarities, but they focus on different things. Biochemical Engineering uses bioreactors to make food medicine and handle waste. On the other hand, Chemical Engineering uses raw materials to create finished products by altering their chemical or physical makeup, structure, or energy content through chemical processes.
Comparing the Two Fields
Both chemical and biochemical engineering programs typically emphasise core subjects like mathematics, chemistry, and physics. However, biochemical engineering programs also include extensive biology, microbiology, and biochemistry coursework. Students pursuing biochemical engineering should expect a curriculum that blends engineering principles with life sciences.
Chemical engineers need strong analytical skills, problem-solving abilities, and a deep understanding of chemical processes. They frequently tackle large-scale industrial challenges and must excel at managing complex systems.
Biochemical engineers also require strong analytical skills and a solid understanding of biological systems and laboratory techniques. Creativity and innovation are crucial in this field, as it often involves creating new products and processes using biological materials.
The demand for chemical engineers remains strong due to the ongoing requirements in energy, pharmaceuticals, and consumer goods industries. Chemical engineers are also playing a greater role in developing environmentally sustainable technologies as industries seek more sustainable practices.
Biochemical engineering is growing rapidly, especially in biotechnology and healthcare sectors. Advances in genetic engineering, synthetic biology, and bioprocessing are broadening the possibilities for biochemical engineers. This field is pivotal in addressing global issues such as healthcare access, environmental sustainability, and renewable energy.
Choosing between chemical and biochemical engineering depends on your interests and career goals. If you're intrigued by industrial processes, chemical reactions, and materials science, chemical engineering might be the best choice. However, if you are passionate about biology, biotechnology, and creating innovative solutions with living systems, biochemical engineering could be more suitable for you.
