Why CETI Enterprises

Two generations. One plant. One partner who speaks both languages.

Many plants and family businesses are at a turning point. The people who built them want reliability. The people taking them forward want speed. You need both.

If you built the plant

You trust what has been proven.

You know your plant by its process: recovery, caustic, energy and people. You want it to run reliably and cost less per tonne, without risky experiments.

What we bring

  • Process and energy audits
  • Debottlenecking and capacity improvement
  • Training that passes your know-how on

CETI Enterprises speaks both languages.

Process engineers who understand digestion and precipitation, working alongside digital specialists who understand WhatsApp, AI and dashboards. Together we turn your plant's experience into a business the next generation can grow.

If you're taking it forward

You see what could be faster.

Enquiries scattered across phones, reports in spreadsheets, decisions waiting for a call. You want tools the whole team will actually use.

What we bring

  • WhatsApp CRM for sales and support
  • AI automation of routine work
  • Dashboards on your phone
Our journey

From bauxite to bytes.

How a team of alumina plant engineers became a partner for digital transformation, without losing what made them trusted.

Questions we hear

Before you get in touch.

We're a traditional plant. Is digital transformation right for us?

Yes, if it solves a real problem. We start with your process and your people, not with software, and suggest small, practical steps that prove their value before anything bigger.

Does my team need technical skills to use WhatsApp CRM or AI automation?

No. We set things up around tools your team already knows, such as WhatsApp and spreadsheets, and train them until they are comfortable.

Do you only work with alumina plants?

Our engineering roots are in alumina, hydrate, coal carbon and specialty chemicals. Our digital and AI services are for businesses of every size and sector.

Is the Bayer Process Masterclass online or at our plant?

Both. It runs online for participants anywhere, or onsite for your team, with modules tailored to your plant. See the full curriculum.

How much does it cost?

It depends on the scope. After a short conversation about your plant or business, we share a clear proposal with costs and next steps.

How do we get started?

Send us a WhatsApp message with a line about what you need, or call us on +91 83800 43065. We'll take it from there.
