This paper focused on the evaluation of burning performance of the traditional organic insulation materials for external wall of building, such as XPS, EPS and PU foam. Results of full-scale fire testing showed that if the LOI of organic materials reach Class B2 requirements, and the organic insulating layer has been protected by thin plastering, then the fire will not spread during the full-scale practical fire testing.

Formation Design

The sandwich external wall panel is made of fireproof Paper Honeycomb Board (PHB) as kernel material, and the external surface is covered by colorful extruded steel board, while the internal surface is coated with the thermal insulating frothing ceramic board or the calcium silicate board, which works as the insulating layer or protecting layer of the panel. Two types of formation design are suggested, i.e., Type-A and Type-B. After corresponding thermal calculation, the maximum thermal transmission factor is determined as 0.424W/(m2• K), which complies with the threshold stipulated in the National Code for external wall panel used in cold climate area. The newly designed wall panel will save 65% of energy when compared with the traditional one made in 1980.

EPS, XPS and PU plates etc. are often selected as the insulating layer in external thermal insulation system. Although featured by good thermal insulation properties and low costs, these materials are provided with major fire potential. Therefore, fireproof treatment methods for the thermal insulation materials and fireproof structural measure for the system are proposed in this paper based on the combustion tests on the thermal insulation materials, so as to increase the fire protection safety of the external thermal insulation system.

Cone Calorimeter Test

This paper focused on the evaluation of burning performance of the traditional organic insulation materials, such as XPS, PU and phenolic foam. Cone calorimeter test indicated that PU showed a well flammability. After the combustion process, most of the XPS was melted, and most of the phenolic foam was burned. SBI test showed that the burning grade of XPS, PU and phenolic foam insulation board are in the region of grade B to Grade D, can not achieve grade A. All XPS samples can reach to level ZA3, however, some PU and phenolic foam samples can not reach to level ZA3.

The anaerobic digestion process converts organic materials into a methane-rich biogas. The KwaZulu-Natal region has the potential to attract a significant amount of industry. The objective of this research was to assess the feasibility of using anaerobic digestion as a treatment method for high-strength or toxic organic effluents. A strategy was developed to evaluate the degradability and toxicity of effluents and, ultimately, predict the efficiency of treatment in a full-scale digester. This paper details the strategy and investigates the degradation potential of a textile size effluent (COD ca. 140,000 mg/l). The ultimate degradability of the effluent was determined as well as the concentrations and volumes, which could be treated effectively. The inhibitory components of the size effluent were found to be Plystran (10 mg/l) and the biocide (5 mg/l). Anaerobic digestion was found to be feasible, on a laboratory-scale. These results are being applied for scale-up, to full-scale implementation in an existing anaerobic digester.
