“…This result matched that the research results of the microalgae and the rice straw were done by previous researchers [23][24]. At a microwave power of 400 W, the maximum temperature and average temperature-rising rate were only 191 °C and 0.316 °C/s respectively.…”

“…When the microwave power was 500 W, the yield of bio-oil was maximised at 29.53 %. As the microwave power was increased to 700 W, it was reduced to 26.20 % because excessive microwave power resulted in a higher temperature in the tobacco stems, which promoted secondary pyrolysis of the steam of the bio-oil(s) [24][25].…”

“…The mechanisms involved in generation and modification of pyrolysis products from microalgae are still poorly understood. Hu et al [12] reported that when Chlorella vulgaris was pyrolyzed by microwave treatment, 35.8% of bio-oil was obtained at 1500 W microwave power. These authors also achieved a gas yield of 52.4% at 2250 W microwave power.…”

Pyrolysis-gas chromatographic mass spectrometry (Py-GC/MS) was used to determine the yield and chemical composition of the pyrolysis products of Schizochytrium limacinum. The pyrolysis was carried out by varying the temperature from 300 °C to 800 °C. It was found that the main decomposition temperature of Schizochytrium limacinum was 428.16 °C, at which up to 66.5% of the mass was lost. A further 18.7% mass loss then occurred in a relatively slow pace until 760.2 °C due to complete decomposition of the ash content of Schizochytrium limacinum. The pyrolysis of Schizochytrium limacinum at 700 °C produced the maximum yield (67.7%) of pyrolysis products compared to 61.2% at 400 °C. While pollutants released at 700 °C (12.3%) was much higher than that of 400 °C (2.1%). Higher temperature will lead to more pollutant (nitrogen compounds and PAHs) release, OPEN ACCESSEnergies 2013, 6 3340 which is harmful to the environment. Considering the reasonably high yield and minimum release of pollutants, a lower pyrolysis temperature (400 °C) was found to be optimum for producing biofuel from Schizochytrium limacinum.

“…Hu et al [81] showed the enhancement of the microwave-induced pyrolysis reactions of the microalga Chlorella vulgaris by mixing it with activated carbon, CaO, SiC and the solid residue obtained from the pyrolysis of the microalga. Under 1,500 W, the gas yields increased by 75.7, 50.0, 24.5 and 25.8 % with respect to the pyrolysis of the pure microalga.…”

Bioplastics production is a growing industry that offers an alternative to that of conventional fossil-derived plastics. Polyhydroxyalkanoates are biopolymers whose thermo-mechanical properties can be comparable to those of conventional plastics. Polyhydroxyalkanoates can be produced through the bacterial fermentation of carbon substrates, although to be commercially viable cheap renewable resources such as syngas (CO + H 2 + CO 2 ) from waste pyrolysis are required. Microwave pyrolysis has been demonstrated to have the potential of maximising both the gas production and syngas concentration. Hence it is an appropriate thermochemical route for further syngas fermentation. A combination of different factors, such as the type of waste, the moisture content, the pyrolysis temperature or the use of a microwave receptor makes microwave pyrolysis highly versatile, so that the syngas produced can be virtually tailored to the specific requirements of the bacteria.
