Effective Wastewater Treatment in Meat Processing industries


With the rise in the economy, meat consumption in India has grown. Nearly 70% of people in India prefer nonvegetarian food. In 2020, the population of India had consumed over six million tonnes of meat. According to the Ministry of Food Processing Industries, India accounts for 2.18 per cent of global meat production. It ranks sixth after China, The United States of America, Brazil, Russia and Germany.

The brewery industry is the most traditional industry that manufactures alcoholic beverages. Beer production requires a large quantity of water, especially in the brewing and filling processes. Even though the production process varies in the different breweries, these industries discharge significant effluents. The brewery industry is considered an important economic segment of the country. However, the byproducts generated, including mashing and yeast surplus, are responsible for causing pollution when mixed with the effluents such as sugar, soluble starch, ethanol and volatile fatty acids. 

With the increased requirement for food supply, biostimulants have become one of the most commonly used stimulants in the agriculture industry. With their recent popularity, traditional stimulants such as fertilizers and pesticides can be easily replaced due to the biostimulant’s unique method of influencing growth and development in more than one way. Compared to traditional fertilizers, Biostimulants offer much more potential growth by improving yields and crop quality.

The dairy industry is the largest polluter of water generating an estimate of 2.5 to 3 liters of wastewater for every liter of milk processed. The efficiency of wastewater treatment management for dairy industries is based on the daily volumetric loading and flow rates. However, it becomes complicated as each milk product requires separate technological cues, resulting in regular effluent composition change.

It’s no secret that the world’s fish stocks are in a poor state. Overfishing, trawling, ocean pollution and climate change have led to depletion in the number of fish in our oceans. Subsequently, the oxygen levels in our oceans have also decreased. Some scientists have even speculated that by 2048 there will be no fish left at all. So, could farmed fish be the solution?

Urban gardening is cultivating and processing food in and around urban localities. Urban gardening also involves animal husbandry, aquaculture, beekeeping and horticulture. Essentially, it is a conventional crop growing in a city setting. With urbanization and the desire of more people to do their farming where they live, urban gardening has become a popular and effective option – a departure from the conventional belief that crop production can only be done in rural areas.

With the alarming rate at which groundwater is disappearing, water is becoming a critical component. Clean water has become more critical than ever in today’s world. We know water covers 70% of our planet, and we always think it is plentiful. However, freshwater, i.e. the water we drink, bathe in and irrigate our farm fields with, is incredibly rare. Only 3% of the world’s water is freshwater, two-thirds of which are frozen glaciers or unavailable for our use. Around 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year.
