Problems solved by technology

A lot of organic matter, especially meat, is not suitable as fertilizer because it e.g. emits a foul smell (sometimes intolerable)

Embodiment

[0041] 1. Production of meat-based water-retaining polymer composites

[0042] Prepare 100 ml of a 30% alkaline solution (5 g KOH and 25 g NaOH). During this (exothermic) process the water temperature rose from 23°C to 60°C. 100 g of organic waste (minced meat) was dissolved in the solution, which lowered the temperature of the solution to 55°C. The high temperature and highly alkaline conditions of the solution can result in a 6 log reduction in total viable count (see below). Once the temperature of the solution had dropped to 45°C, 30ml of acrylic acid was added. This raised the temperature to 62°C. After 5 minutes, 0.5 g of ammonium persulfate (APS) was added to the solution as a polymerization agent and polymerization occurred within 15 minutes. APS was added to the solution to raise the temperature of the solution to 70°C. The resulting complex had a pH of 7.7.

Abstract

The inventors provide a method of processing biological material into a water- retaining polymer complex, a water- retaining polymer complex obtained from said method, and the use of said water- retaining polymer complex to improve the water retention and / or nutrient content of soil. The method comprises the steps of providing said biological material, an alkaline solution and a monomer, then adding a polymerisation agent to form a water- retaining polymer complex.

Description

field of invention [0001] The present invention relates to the processing of biological material. Background of the invention [0002] Following the outbreak of bovine spongiform encephalopathy (BSE) in the 1980s and the subsequent ban on the use of meat and bone meal (MBM) in animal feed, several attempts have been made to create useful end products from dead livestock. In Europe, certain MBMs are used as ingredients in pet food. Furthermore, MBM is increasingly being used as an environmentally sustainable coal substitute for the production of renewable energy or as a fuel in cement kilns. However, MBM has only about two-thirds the energy value of fossil fuels such as coal. Thus, unfortunately, most MBMs are simply placed in landfills or incinerated. [0003] The inventors of the present invention have noticed the fields linking MBM disposal / use and soil conditioning / fertilization. Conventional inorganic fertilizers have the great disadvantage of being highly water solu...
