From waste to alternative fuel

The production of refuse-derived fuel (RDF) from municipal solid waste (MSW) is an interesting alternative to the use of high calorific portion of MSW as fuel for energy production, elaborate Ramky Enviro Engineers.

M unicipal solid waste (MSW) is one of the high potential wastes to be used as a fuel for energy production due to extremely large quantity with low cost. The production of refuse-derived fuel (RDF) from MSW is an interesting alternative to the use of high calorific portion of MSW as fuel for energy production.

MSW can be used as co-fuel for biomass power plant or as a substitute fuel in industrial boiler and co-processing in cement industry. This helps to solve the problem of waste management and conserve energy, while reducing environmental impact and greenhouse gas (GHG) emissions.

The light combustible fraction (like paper, biomass, textiles, etc.) separated from the MSW is generally called RDF fluff. It will have a calorific value in the range of about 2,200 to 3,000 kcal/kg with 15 to 20 per cent moisture. About 28-35 per cent of RDF fluff is estimated to be generated from the dry segregated MSW. The material received after pre-segregation/sorting with greater than 100 mm size contains mostly combustible materials. Before sending for final preparation of RDF, the material will be stored in the RDF storage area.

RDF storage, processing and handling
Once sorted, the material is loaded and sent for RDF storage area after weighing. The storage is to be carried on the impermeable layer (i.e.; RDF storage facility) as the waste contains high moisture content and produces leachate. After storage of RDF, material is sent to RDF processing plant for further processing. RDF process includes:

  • Feeding
  • Shredding
  • Screening
  • Density separation.
  • Baling and fluff
  • Packing and dispatch

After presorting and coarse segregation process, the over material is put into the feeding conveyor. The feeding conveyor transports the RDF martial to the shredder unit. The material is then shredded and sent to the screening section for further processing. Afterwards, the shredder material is screened, and the dirt material is removed. After completion, the material is sent for air density separation. The high density material is then separated and the light fraction is used as a major fuel source.

This RDF is being co-processed in the cement industry. The cement industry kiln is capable of burning the MSW – RDF. Since the cement kiln has high-residence time and the high temperature range is around 1,200 to 1,500 degree Celsius, this will ensure 100 per cent combustion of RDF. Thereby, the vent out gas will contain less pollutant and it will meet the specifications stipulated by the regulator. All cement industries stack emission monitoring by CEMS and report is connected online to the respective SPCB.

In the current financial year, Ramky Enviro Engineers Ltd has dispatched around 20,000 MT of RDF from its Hyderabad site to various cement industries. The below-mentioned specifications are maintained uniformly to have better fuel efficiency. Specifications of RDF is sent to the cement industry as a fuel:

1.Gross calorific value to be maintained, i.e., 2,300 to 3,200 Kcal/Kg
2.Moisture content below 20 per cent
3.No metals or earth material which poses serious threat to the shredder and the cement factory kiln
4.Un shredder size above 200 mm thickness
5.Secondary shredder size reduction below 100 mm thickness
6.Chlorine <1.5 per cent

As per the Solid Waste Management Rule 2016, mentioned in Definition 38, RDF can be used by the cement industry as a better fuel source. This can replace the fossil fuel as an endangered source in nature. Moreover, the fossil fuel is the major source of greenhouse gas emission.

Methane is a particular potent greenhouse gas. Emission from the fossil fuel is the major source. The global warming potential of methane gas is 25 times than that of carbon dioxide, the methane emitting from land fill is huge and could create a havoc to the atmosphere. By using RDF, the potent air pollutant can be reduced drastically.

By reducing 1.6 kg of carbon dioxide by using per kilogram of RDF, a holistic MSW has a positive consequence on greenhouse gas emission derived fuel. European countries like Netherland, Switzerland and Norway use more than 83 per cent of MSW RDF for co-processing. In India, the RDF utilisation is below 1 to 1.5 per cent of the huge available source.

In cement production, the fuel cost is about 30-40 per cent. By using RDF, the fuel cost will be reduced drastically. A long way is required to replace RDF as a fuel source in Indian context. The cement industry can play an important role in the urgent global need for destruction of MSW to the greater extension. Due to the availability of huge quantity, the cement industry should come forward to use RDF, thereby huge fuel cost can be saved.

Impactful Branding

Published

Advertising or branding is never about driving sales. It’s about creating brand awareness and recall. It’s about conveying the core values of your brand to your consumers. In this context, why is branding important for cement companies? As far as the customers are concerned cement is simply cement. It is precisely for this reason that branding, marketing and advertising of cement becomes crucial. Since the customer is unable to differentiate between the shades of grey, the onus of creating this awareness is carried by the brands. That explains the heavy marketing budgets, celebrity-centric commercials, emotion-invoking taglines and campaigns enunciating the many benefits of their offerings.
Marketing strategies of cement companies have undergone gradual transformation owing to the change in consumer behaviour. While TV commercials are high on humour and emotions to establish a fast connect with the customer, social media campaigns are focussed more on capturing the consumer’s attention in an over-crowded virtual world. Branding for cement companies has become a holistic growth strategy with quantifiable results. This has made brands opt for a mix package of traditional and new-age tools, such as social media. However, the hero of every marketing communication is the message, which encapsulates the unique selling points of the product. That after all is crux of the matter here.
While cement companies are effectively using marketing tools to reach out to the consumers, they need to strengthen the four Cs of the branding process – Consumer, Cost, Communication and Convenience. Putting up the right message, at the right time and at the right place for the right kind of customer demographic is of utmost importance in the long run. It is precisely for this reason that regional players are likely to have an upper hand as they rely on local language and cultural references to drive home the point. But modern marketing and branding domain is exponentially growing and it would be an interesting exercise to tabulate and analyse its impact on branding for cement.
