In 2016, a study was conducted regarding waste heat potential in Pakistan. The research article, aptly titled “A Survey on Waste Heat Recovery: Electric Power Generation and Potential Prospects within Pakistan”, was published in the journal Renewable and Sustainable Energy Reviews, which is a peer-reviewed journal that publishes scientific research every year.
The survey is about waste heat recovery and how it can aid in energy consumption. It talks about using Thermoelectric Module in order to make waste heat into useful, electric energy. This has many benefits, including running loads, storing energy, exporting power, being environmentally friendly, and, most importantly, maintaining economic growth, all of which is important to MMG Pvt. Ltd.
The research paper goes on to review the relevant research that exists on waste heat recovery technologies, focusing mainly on TEG (thermoelectric generator). This new but rapidly growing technique has a simple structure, long lifespan, scalability, and a solid state operation. The paper also discusses the potential applications of thermoelectric generators in Pakistan, the country’s current energy status, and how waste heat recovery holds immense potential within the cement industry.
A MATLAB and Simscape simulation of a thermoelectric generator model in Officer Colony, Abbottabad, Pakistan, was used as a case study. The model simulates performance and generates data on their current, voltage, and power output. It analysed the potential of waste heat recovery in a residential community called Officer Colony, and studied 30 different homes. The researchers looked at various heat-related appliances, including cooking stoves, gas heaters, and gas geysers.
The study focuses on using thermoelectric generators to reduce the amount of heat wasted by these appliances by converting waste heat into useful electrical energy. Such innovative ideas are used by MMG Engineering Private Limited’s engineering consultants, who think of better solutions for their clients to decrease waste and increase efficiency.
The research concludes that TEGs are a promising technology for waste heat recovery and are a milestone in regard to waste heat potential in Pakistan. Although TEGs have high initial costs, they are cost-effective in the long term and are being commercialised in various industries and applications. Future efforts are needed to further improve and commercialise TEGs with higher efficiency. MMG Pvt. Ltd is aware of this advancement and makes use of it in their consulting with clients as they see fit.
