Patent number: 9499440Abstract: An amount-reduction, harmless, disposal method for heavy metal waste gypsum (HMWG), which belongs to the technical fields of recycling economy and environmental protection. The HMWG used as raw material is subjected to processes of smelting fluxpreparation, lead smelting, fuming, and geopolymeric gelling, to realize amount-reduction, harmless and resources recycling utilization of heavy metal waste gypsum. The smoke containing sulfur dioxide produced in the smelting process is sent to the acid making system, and the produced dust with heavy metal is sent to the dedicated system for heavy mental disposing. The smoke dust produced in the fuming process is returned to the lead smelting system. The secondary HMWG produced in the acid making system would be returned to the preparation process of smelting flux. And the final products would be sulfuric acid and geopolymer material.Type: GrantFiled: March 13, 2014Date of Patent: November 22, 2016Assignee: UNIVERSITY OF SCIENCE AND TECHNOLOGY BEIJINGInventors: De an Pan, Shen gen Zhang, Ling jie Li, Bin Guo, Bo Liu

Patent number: 9496059Abstract: A method for securely and safely storing radiocontaminated waste matter and a container therefor are provided. Radiocontaminated waste matter and PSC are mixed and then retained and stored in a tetragonal cylindrical container tank 1 made of steel sheet, concrete, or PSC-containing concrete, so that the spatial gamma radiation dosage of the environment around the tank 1 becomes about the same as that of an environment or place which receives no fall-out radioactive substances. When a mixture of radiocontaminated waste matter and PSC is ashed, and the ash thus obtained is again mixed with PSC, and then loaded and stored in said container tank, the spatial gamma radiation dosage around said container tank is to be similar to that of an environment or place which receives no fall-out radioactive substances, and simultaneously both 134Cs and 137Cs are decreased, and as a result radiocontaminated waste matter can be securely and safely loaded and stored for a long-period of time.Type: GrantFiled: May 8, 2015Date of Patent: November 15, 2016Assignee: CORELEX SAN-EI CO., LTD.Inventor: Ai Van Tran

Patent number: 9492697Abstract: Tissue digestion methods and apparatuses that provide easy, safe and inexpensive disposal of biological tissue, for example animal carcasses and human cadavers, are disclosed. Embodiments include tissue digesters with elongated cylindrical vessels for holding digestive fluid and baskets for holding tissue within said vessel. Embodiments include baskets with perforations to allow circulation of digestive fluid around and about the tissue. In one form the basket holding the tissue is horizontally loaded into a horizontally disposed vessel. The vessel is then tilted to a more vertical orientation. Gravity helps to collect the tissue fragments in a sloped collection region of the basket, which is located near a mixer to allow continual agitation of the tissue fragments as they are digested. The tissue digester can operate efficiently at lower temperature and pressures, is mechanically less complicated, consumes less power and is less expensive to manufacture than conventional tissue digesting systems.Type: GrantFiled: April 29, 2011Date of Patent: November 15, 2016Assignee: Bio-Response Solutions, Inc.Inventors: Joseph H.
