N-Viro Way: Recycling Sludge From Sewerage

Currently, with the environmental temperatures rising high in urban areas and suburbs, people are driven to find havens of relief. One of the closest are bays. But, the waters of most peripheral coves are just too polluted with deluge of sewage sludge brought down by tributaries through rivers. Elsewhere, almost every river system or creek nearby could no longer satisfy peoples need to break away from daunting heat. To make the situation worst, expensive potable water supply is dwindling and estuaries have been turned into breeding ecosystems of pathogens rather than healthy biotic environment of aquatic flora and fauna.

There is only one rational way that tributaries could be sanctioned to adopt. This is the N-Viro way. In fact, N-Viro International Corporation has been in the market since 1993. At the other end of the stick, the company technique is not only aimed at making sewerage water potable, for both human and aquatic dwellers, but, also to make it sanitary for human recreation purposes, for relief from environmental surges in temperatures.

Apart from that, most people are not aware of the fact that sewage sludge is remarkably rich in renewable energy. In fact, it is one of the best sources of alternative energy such as clean coals. This is actually one of the company formulated products which could be presumed as opportunity fuels in the market since 1993 considering the low level of carbon emission from its usages. N-Viro technology collects the solids from sewage sludge by separation procedures. The solids are then purified of microorganisms and turned into clean coals for fuel and fertile soils for farming, gardening and landscaping purposes.

Conversely, practically using what are throw away from companies that are extensively using coal fossil fuels, water is purified. So, what are wastes to energy from fossil fuels’ utilization is a material to recycle water into vapor and make part of it available as clean tap water which could readily be safe and useful for human and aquatic consumption.

Low Back Pain, Limbs Weakness, and Poor Diet

For the past 4 years, I have been into what most people call low back pains and weakness of the limbs. At my age, I thought it was all about genetic inheritance. So, I took time looking after excellent preparations of herbal supplements in addition to low fat diet. But, my pains persisted and I really thought something more is going wrong.

Lately, or some 4 months back, I transfered residence. So, I got to be a bit strict with my budget to make both ends meet while living in a higher cost area. I can not sacrifice though my allocations for the basics. I just considered cutting down some edges for the kitchen without necessary losing sight of the proper diet which I have prefered. For so many years, I have sort of shied away from red meat considering the many health issues that came out about its consumption over and above the cost without really thinking of what I have been depriving my body.

Fortunately, two months back, I met some new acquaintances from the new neighborhood. One of them told me that nearby a store is selling fresh cuts of Halal beef. I enquired and check if it would be cost-efficient. HURRAH! So much was my glee that besides having cut some cost, I relish consuming almost half a kilo per week. Of course, I usually prefer it cooked as well-done steak with fruit juice, rice, and mango on the side. With this kind of diet, I have noticed I gradually have gone over those pains and weaknesses. I told my friend 'Imagine a cow'?
Have you seen one complaining of pains?
