Waste Blog: "Possible Ways To Reduce Waste"

There is lots of waste all over the world it does not matter private or public sector. It all boils down to the production of a given product and as an ending result is waste.  Sustainable alternatives are always available and it just takes an extra step of our part to take those initiatives into effect. Of course one the benefits is less pollution, better air quality, and sustainable environment.
Hospital Waste
7000 tons a day
Type of waste:  “Red Bag” (contaminated with blood, urine, and/or other bodily fluids)
Possible Treatment for waste: "Process and autoclave system for size reducing and disinfecting contaminated hospital refuse" This patent claims to have developed a method and apparatus for comminuting and sterilizing infectious hospital refuse, where a size reduction process takes place within the same container used for sterilization through vacuumization and saturated steam pressurization at atmospheric pressure.

Biosolids Waste

Contain pathogenic microorganisms that cause infection
Type of Waste: land applications that increase the soil quality, but poor handling and management of an application process could harm the environment

Possible Treatment for Waste: "Biosolids flow-through thermophilic treatment process" This invention relates to wastewater treatment, and specifically to a method of treating wastewater sludge using a thermophilic treatment process. The process in this invention consists of two steps: the raw wastewater sludge is pumped continuously into a digester where the treatment process temperature of about 51 °C to 60 °C is maintained. The treated sludge from the first digester is then transferred to another digester where sludge is treated anaerobically, and temperature is not more than 2 °C warmer than the specific temperature in the first digester. The inventors had a total of 18 claims where the first claim describes the process of treatment and all the other claims are referred to the first claim which discusses the period of time for which sludge is exposed to a specified temperature. For a period of time, sludge is kept in first digester.
Industry Waste

Type of Waste: Numerous industries have increased over the years and the production of goods also increased to meet the rising population needs that increased waste emanating from industries.

Possible treatment for Waste:"Method and system for sustainable treatment of municipal and industrial waste water". The inventors claim to have invented a method and system for sustainable treatment of municipal and industrial wastewater. This process has hybrid continuous flow, cyclic operating, substantially constant level, and an activated sludge process with a symmetric functional cycle. There are different phases in the functional cycle which are cyclic, and repeat once the last phase is done.

Construction Waste

"Mobile system for recovering material from construction waste and demolition debris" The system includes a mobile wheeled framework that has at least one station for picking. A hook is mounted on the wheeled framework for selectively picking waste or debris from a construction site. A screen is disposed on the wheeled framework and is configured to receive the waste or debris from the hook. The screen sorts the waste or debris, depending on the size, into fines and oversized material. A conveyor transports the oversized material adjacent at least one picking station to allow removal of selected materials for further processing.

Agriculture Waste

"Method of treating liquid agriculturalwastes" In this process, liquid agricultural wastesuch as liquid manure is purified by a means of algae/bacteria mixture culture and subsequent rotifer culture in a separate stage. The algae/bacteria, which occurs in shallow open air ponds for a period of three to six days at an average temperature of 18 °C, will be used for this process. The algae/bacteria suspension in a rotifer culture mixture is adjusted to a pH of six to eight that can range from two to four days at a temperature of 20 °C. The first claim refers to the process of treating liquid waste, and the other ten claims refer to the conditions and other properties on how the algae/bacteria and rotifers are applied.
