DBL Sustainability Pillars


Social Responsibility: The Environment

Everyday DBL Ceramics, with its two state-of-the-art Waste Treatment plants, treats about 18,000 cubic meters of waste generated during its production process. Therefore, there is zero discharge of the wastewater into the environment by DBL Ceramics.

DBL Ceramics installed dust collectors at almost every stage of the production process to capture dust particles or powder generated during the production process. Moreover, rejected unfired and fired tiles are collected and stored in the right places for further production. Furthermore, all the waste that originated from the production floor is sent to the Waste Treatment Plant for treatment. Consequently, DBL Ceramics poses minimal environmental impact during the production process.

DBL Ceramics has incorporated the most updated machinery with energy-efficient motors (IE2/IE3), inverters to use energy rationally. Moreover, it has facilities like an energy cogeneration system to generate power from hot flow gas generated in Kiln. It can reuse the energy in other types of machinery like Tunnel Dryer, Horizontal Dryer and the Kiln itself. Doing so saves around 40 million cubic meters of natural gas every year. Furthermore, it is implementing the energy cogeneration system by 2022 to generate further energy from the Generator hot exhaust gas to reuse them in Spray Dryer which will elevate the yearly natural gas saving to about 230 million cubic meters from the existing number. Furthermore, instead of using normal T5/T8 tube light, DBL Ceramics installed LED light in the factory premises, saving around 0.44 Kw-H electrical energy per year.

DBL Ceramics uses natural resources rationally. Aiming at reducing underground and raw materials consumption, DBL Ceramics reuses wastewater, spray-dried powder, unfired rejected tiles and fired left tiles in the production process.

Due to complete vitrification in tiles due to high-temperature firing during production, they hold a longer useful lifespan in application than most other flooring materials such as Cork, Vinyl, and Laminate. This feature leads to a reduction in the amount of waste generated.

DBL Ceramics Committees

Collective bargaining agreement is not prohibited in DBL Ceramics. DBL Ceramics has formed multiple committees with more to make a trustworthy relationship between the workers and the company. These committees consist of representatives of both the employers and the workers. The committees hold regular meetings to promote mutual trust, understanding, and cooperation between the employers and the workers. They are working to effectively establish privileges and improve welfare services for the workers and their families.

DBL Ceramics is working towards SDG 15 (Life on Land) and DBL volunteers believe that Tree Plantation Program will help the Earth manage its Biodiversity through a better Carbon performance.

DBL Ceramics encourages good relations between workers and managers, through training on different topics including labor standards, leave days, working hours, wages, personal protective equipment, health and safety, environmental issues, welfare, and so

Innovations in CSR

Bandhan Fair Price Shop: to be expanded in DBL Ceramics:

Initiated in 2008, “Bandhan” is a fair price shop which serves low income workers with all the essentials and commodities at factory price of manufactures. The shop is aimed at reducing workers’ monthly expenditure burden and sheltering them from economic inflation. Any worker of DBL can buy items through zero-cash and on-credit transactions: the bills are simply adjusted with their salaries at the end of the month.

Bandhan was featured in the UN Global Compact’s Industrial Manufacturing document under SDG-1. Bandhan also earned DBL a membership to the Business Call to Action (BCtA), a global platform of the United Nations Development Program (UNDP) on inclusive and sustainable business (www.businesscalltoaction.org/member/dbl-group).

DBL Ceramics has also been onboarding “Bandhan” to help save the money and reduce the monthly expenditure burden of the workers.

Children’s Education Support Allowance (CESA):

A set of programs exist under the Children Education Support Initiative which focuses on accessibility to education for all the employees of DBL. These consist of:

  1. Recognition for meritorious students
  2. Sponsoring two children of each staff and worker whose monthly income is below BDT 25,000
  3. Providing career path counseling to students who have passed Higher Secondary education

In 2018, 88 students received acknowledgement and 8,365 students were provided scholarships worth BDT 44,762,360 from DBL. As a part of the esteemed conglomerate, DBL Ceramics has also been providing Children’s Education Support Allowance to the workers.

Natural Gas Saving Through Heat Recovery

Tunnel Dryer:

Hot exhaust gas from Kiln is extracted at about 120O Celsius. This exhaust gas is used to preheat the green tiles before entering into the firing furnace.

Doing so, DBL Ceramics Ltd. saves about 11,508.50 cft natural gas.

Flow Rate [kg/Day] Exhaust Temp. at Tunnel Dryer [°C] Green Tiles Temp [°C] Average Cp at 120 °C [kCal/kg] Saved Thermal Power [kCal/Day] Natural Gas LTP [kCal/Nm3] Saved Gas Flow Rate [Nm3/Day]
124,200 120 25 0.25 2,794,500 8,600 324.94

Thus, in 2 tunnel dryers, DBL Ceramics is saving 11,475.15x2 cubic feet Natural gas per day.

Preheating of Green tiles:

Hot exhaust gas from Kiln is extracted at about equal to or more than 200O Celsius. This exhaust gas is used to preheat the green tiles at the entry of the firing furnace before the tiles enter into the furnace to be fired.

Flow Rate [kg/Day] Exhaust Temp. at Kiln Entry [°C] Green Tiles Temp [°C] Average Cp at 200 °C [kCal/kg] Saved Thermal Power [kCal/Day] Natural Gas LTP [kCal/Nm3] Saved Gas Flow Rate [Nm3/Day]
125,040 200 30 0.25 5,314,200 8,600 617.90

Thus, DBL Ceramics Ltd. is saving about 21,820.933x2 cubic feet of natural gas consumption per day in two kilns.

Heat recovery from Kiln to Horizontal Dryer:

DBL Ceramics Ltd. is using hot flow gases from Kiln in three horizontal dryers.

Flow Rate [kg/Day] Exhaust Temp. at Horizont al Dryer [°C] Dryer Outlet Temp [°C] Average Cp at 500 °C [kCal/kg] Saved Thermal Power [kCal/Day] Natural Gas LTP [kCal/Nm3] Saved Gas Flow Rate [Nm3/Day]

Underground water saving Through 100% Wastewater Recycling

Recycle of wastewater for production process:

DBL Ceramics Ltd. is operating two WTPs namely glazing water treatment plant and polishing water treatment plant. We treat 100% of wastewater produced in the production process.

  1. Glazing water treatment plant: Recycling Capacity 12.5 m3/hr.

We are running the plant 22 hours per day. So, it is recycling 275m3/day of wastewater (3,011,250 m3/year) which we use again in the production process.

  1. Polishing water treatment plant: Recycling Capacity 360 m3/hr.

We are running the plant 22 hours per day. So, it is recycling 7,920 m3/day of wastewater (2,890,800 m3/year) which we use again in the production process.

By this way, DBL Ceramics Ltd. is conserving under water reservation and protecting the environment from pollution.

DBL Ceramics Ltd. is treating around 5,902,050 cubic meter wastewater per year.

Reuse of Wastage Tiles

DBL Ceramics Ltd. has a crusher plant to crush fired wastage tiles into small chips. Instead of dumping these defected tiles, DBL Ceramics Ltd., reuses these small chips in the production process. Thus, DBL Ceramics Ltd. dumps no wastage tiles into the environment to protect the environment from being polluted.

We use around 7-10% of fired rejected tiles per day which saves the same quantity of natural clay and stones.

DBL Ceramics Ltd. also uses the green wastage tiles/powder in the production process. It uses around 10-15 tons of green wastage daily.
