MASARO technology presents a solution in solving the waste problem through an organic waste processing unit, known as IPPO (Organic Fertilizer and Feed Industry). The Masaro system characterises solid waste into five catagories including organic waste, low value plastic waste, incenerated waste, recycled waste, and hazardous waste. The organic waste will be separated into an organic fast-decaying waste to produce POCI (Special Liquid Organic Fertilizer) and KOCI (Special Liquid Organic Concentrate), and an organic slow-decaying waste to produce a compost. POCI is used as an organic fertilizer and its farming produces a higher production number, higher quality product, faster production rate while its production cost is lower. KOCI and compost is applied in the farm industry where the organic waste with low economic value is used as a raw material to produce new materials with higher economic value. These products can produce an environmentally friendly system and reflect the circular economy principle application. The organic waste is used as raw material for IPPO and its products form a circular economy through aplication in the farm industry that create lower cost production and sustainable development.

Photocatalytic oxidation is one of the technologies to overcome pollution that can be applied for air and water purification. TiO2 has been widely used as a photocatalyst, however, several disadvantages of TiO2 including low absorption of visible or solar radiation, rapid recombination of electron and hole as well as low stability limits its practical applications especially for wastewater treatment. Thus, to overcome this problem, this study aims to develop highly adsorbent photocatalyst using TiO2/SiO2 composites with sugarcane bagasse waste act as SiO2 source. The experimental results show that the photocatalytic performance of TiO2/SiO2 composite in the decolorization of methyl orange exhibits three-fold enhancement compared to neat TiO2. Several catalyst characterizations were obtained including X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray fluorescence (XRF). Characterization data show that a phase transformation was obtained from amorphous to crystalline phase by increasing TiO2 content. These results proved that the feasibility of SiO2 from sugarcane bagasse waste coupled with TiO2 can be utilized for wastewater degradation.
