From waste to commodity: transforming shells into high purity calcium carbonate

Effects of experimental variables on conversion of cockle shell to calcium oxide using thermal gravimetric analysis

“…Production of cockles in Malaysia (Izura and Hooi, 2008). Table 1 Comparison of oxides content in sea shells and limestone (Li et al, 2009 reached 600e700 C. According to Barros et al (2009), sample will experience weight loss initially at 100e140 C due to the trapped moisture and once the temperature increased to 250e410 C, volatile matter will start to dissociate. Upon increasing the temperature up to 500e540 C, the remaining organic material also started to dissociate and finally at 650 C, the sample rapidly disintegrated into CaO.…”

Turning waste to wealth-biodegradable plastics polyhydroxyalkanoates from palm oil mill effluent – a Malaysian perspective

“…Thus, existing wastewater treatment system in palm oil mill is considered as one of the major contributors of green house gas (GHG) emissions in Malaysia. Nevertheless, to become sustainable, palm oil industries should adopt new green and clean technologies to reduce or prevent waste generation at source (Gomes et al, 2007;Klemes and Huisingh, 2008;Basiron and Ma, 2001) and reduce energy consumption and GHG emissions (Klemes and Huisingh, 2005) and finally to recover waste for the generation of resources (Barros et al, 2009;Catarino et al, 2007).…”
