City’s three innovators create bin that converts liquid waste into fertiliser






Pratik Harde, Prateek Malhotra and Ritu Malhotra

By Vikas Vaidya
In most houses leftover food is either dumped in sink, bathroom, toilet or by roadside. Often, food containers get stuck in drains leading to choking of drainage line making it difficult for anybody to clear it. The unclear drain, drainage lines and leftovers thrown by roadside pose health hazards to not only the dwellers but also other residents.
Taking cognisance of health and hygiene of citizens, three young Nagpurians have come up with a solution -- Ezy Liquid Disposal Bin and Ezy Vomit Bag -- to the growing
problem. Their innovation is not only useful in clean disposal of liquid waste but also in converting it in hybrid
fertiliser.
Acknowledging its usefulness, the product was adjudged ‘The Best Innovation’ by Godrej recently.
The young innovators are Pratik Harde, Prateek and Ritu Malhotra. The trio has founded ‘Innovations’ through which they have come up with three more products and acquired patents for the same.
Elaborating about the latest product, Pratik Harde said, “Liquid waste is one of the growing sanitation concerns around the world. India generates 62 million tonnes of waste every year, of which less than 60% is collected and around 15% is processed. The generated waste can be divided
Organic (all kinds of biodegradable waste), dry (or recyclable waste) and biomedical (or sanitary and hazardous waste). Waste from the hospitality industry consists of both wet (organic/biodegradable) and dry waste. The wet waste consists primarily of food waste, which can account for more than 50% of the hospitality waste (Curry). Million liters of liquid waste are generated each day in hospitality industry which is disposed in sewages or dumped in open areas.”
“We came up with Ezy Liquid Disposal Bin in which we have applied macro molecule pulp. It gets mixed with the liquid waste which is converted into semisolid and the end product is hybrid fertiliser. This hybrid fertiliser can be used as landfill closures, petrochemical spills, and other environmental clean-up projects. It reduces waste transportation (as the need to carry liquid waste somewhere else does not arise) and disposal costs from these operations by solidifying liquid waste while minimising an increase in weight and volume. We have received approval from Environment Protection Agency,” said Prateek Malhotra.
“It can be used by energy companies to solidify the liquid waste by-products of oil and gas drilling, and mining. wherever industry has a need to solidify a liquid waste stream – whether for manufacturing, maintenance or environmental cleanup,” pointed out Ritu Malhotra.
The unique characteristics of it is, besides their ability to absorb the highest volume of water or organic fluids, it resists biodegradation and retain their absorbed liquid under pressure; all of which it ideal for waste disposal in landfills.
Ezy Liquid Disposal Bin contents are non-toxic and non-hazardous (when mixed with fresh clean water you can eat it). Nausea is one of the common problems during travelling which creates discomfort to the fellow travellers but Ezy Vomit Bag does not have that issue. In fact, it emits fragrance.

foreign returned MBBS students not to be admitted in PG in State quota

· By Vikas Vaidya Though Medical Council of India (MCI) has relaxed the rule of giving Eligibility Certificate for the students wanting to study in foreign countries, the troubles have not ended so far. Now Maharashtra Government has refused to give admission in the State quota of Post Graduate intake. Due to severe shortage of MBBS seats in the country, most of the Indian students are opting for medical colleges in China, Russia, Central America, the Philippines among others every year. Getting the degree in these countries is relatively cheaper. A student can complete MBBS abroad in less than Rs 30 lakh. In the state, the student has to pay, apart from the fee, a donation of up to Rs 80 lakh to get a seat in management quota. All this totals to Rs 1.5 crore. Earliers these students had to obtain eligibility certificate from MCI. This data has been obtained from Board of Intermediate Education to verify the age and qualifications for doing MBBS in foreign countries. Now MCI has

    By Vikas Vaidya WHEN 45 year-old Kusum Wankhede of Kolhu village, Katol tehsil came to Indira Gandhi Government Medical College and Hospital (IGGMCH), nobody thought that her case would throw a light on new disease as far as medical fraternity of Central India is concerned. She had multi-organ dysfunction with involvement of liver, kidneys, lungs and meningitis and her platelets were reduced. Malaria and Dengue were suspected and ruled out by specific blood tests. Scrub Typhus was suspected when careful examination revealed a black mark (left by mite’s bite) called eschar was noticed over the patient’s right side of the chest. The eschar, which occurs at the site where the mite bites is the single most clinical diagnostic clue. Dr Prashant Joshi, Professor and Head, Department of Medicine, IGGMCH checked her and identified that she was suffering from Scrub Typhus, a new disease in human. It was identified earlier in other parts of the countr
