Jnana Prabodhini, an Educational organization based in Harali, Solapur, visited Vigyan Ashram. They saw the incinerator designed for 5-6 pads and recognized their need for it. They placed an order with us, and afterward, DIC Heads decided to entrust me, to fulfill this responsibility. They had envisioned creating an entrepreneur who could help take the sanitary napkin incinerator—developed at the Ashram—further in the market.

Accordingly, Dr. Dixit Sir, who is the head of DIC, asked me to fill out a Google form, and here it is –

Title of project :–

       LPG Based Sanitary Napkin Incinerator (5-6 Pad).

Responsible Person :-

Siddhant Said.

Introduction / Background :–

  • Inadequate disposal of sanitary napkins leads to hygiene issues and environmental pollution.
  • Schools and hostels often lack proper disposal facilities, increasing health risks.
  • The LPG-based incinerator provides an eco-friendly, hygienic solution for sanitary napkin disposal.
  • Compact design (70×30 cm) makes it suitable for small spaces like hostel washrooms.

Need of the Project :-

  • Traditional disposal methods can cause blockages, odors, and unhygienic conditions.
  • The principal of a school having girls’ hostel requested a solution to address these issues.
  • This incinerator offers a safe, discreet, and efficient disposal method, reducing waste to minimal ash.

Objectives :-

  • Provide a safe, hygienic disposal method for sanitary napkins.
  • Reduce environmental impact and health risks from improper disposal.
  • Ensure compact, user-friendly design for hostel use.
  • Promote eco-friendly practices in waste management.

Idea :-

  • Develop a compact LPG-based incinerator for 5-6 pads.
  • Use LPG for quick, clean incineration that reduces waste to ash.
  • Ensure ease of use and safety in design, ideal for small spaces.

Methodology :-

  • Design: Design a 70×30 cm incinerator and make its BOM.
  • Purchase: Purchase the required material.
  • Fabrication- Build a system for efficient incineration.
  • Testing: Ensure it handles 5-6 pads effectively and operates safely.
  • Installation: Set up in the hostel & train users and maintenance.

Client & Funding details :-

       Gauri Kapre.

Possible end-users :-

       Hostel Girls.

Starting date & Ending date :–

       02/10/2024 To 18/10/2024.

I took on this project and began working towards its completion.

Initially, I planned to use an Arduino board for the control unit. However, one of our DIC alumni, Er. Vrushabh Zunjurkar, who was also involved in the development of the incinerator, suggested the idea of creating a custom PCB using the XIAO board for control. Dr. Dixit Sir agreed with this approach and called Vrushabh to design the electronics for the incinerator. With this new direction, we got started on the project.

When starting the project, I first created a Rough sketch to get a clear idea of the dimensions and where each part would be assembled.

After that, I prepared a bill of materials, listing all the necessary components, their costs, and sources. To purchase the required parts.

After creating Bill of Materials. I made a Tentative quotation, which we sent to Dnyanprabodhini.

After receiving their confirmation, We then began working on the electronics. First, we checked how much current and voltage the spark plug in the burner needed. Based on that, we should designed the circuit.

We operated it at different voltages like 3V, 4V & 5V to figure out the maximum current it needs. Then, we used that information to design the circuit.

Then I took a piece of metal sheet and bent it on all four sides to make a support.

Then I Cut 1/2 Inch Square tube at 45 degree to make door.

and then welded it like this to make a door.

Then To make the inner chamber I created the part in SolidWorks as per drawing, and then converted it to DXF format. With Mahesh’s help, cut a 2.5mm sheet on a plasma cutter.

Then I bent it using a bending machine.


Then I joined the two plates of the inner chamber together using CO2 welding. Then, I smoothed out the sharp corners by grinding them down.

Then I started designing outer shell

Actually, I was planning to build the outer chamber at the ashram itself. But due to a lack of bending machines, I decided to have it built outside. I’ll get it laser-cut and bent because laser-cutting has a better finish. We have a plasma cutter at the ashram, so I’ll laser-cut it.

After making cutting bending Files i started to take quotations from different different laser cutting and bending Companies.

Among them we chose kakade laser & here is their Order.
