Plastic is a material that is used to a great extent. Nowadays Petroleum based plastics are widely used for the commercial purpose. This kind of plastics can take more than a century to degrade. Man made plastics have Polyurethane and Polyethylene polymers. It cannot be easily degraded by micro organisms as it don’t recognize as food. When burned plastics release cancer causing carcinogenic chemicals that are harmful to people and the environment. One eco friendly alternative the current commercial plastic is “Bio plastics”. Bio plastics are biodegradable plastics that have components derived directly from renewable raw plant materials. Seven type of bioplastics were made using various combinations of renewable raw materials and plasticizers. In this project, Cassava starch is used as a main biopolymer for the production of bio degradable bags.

<p>Plastic is a packaging materials that are widely used but has an adverse impact on the environment because it is difficult to degrade in nature. Production technology of biodegradable plastics from natural resources that have characteristic environmentally friendly has developed. Starch-based biodegradable plastic is a widely developed type because the production process is simple and the raw materials more readily available. The starch of cassava and sago has potential as a raw material of biodegradable plastic because of the availability and its characteristic. Also, to make starch as the main ingredient, plasticizers and structural strengthening materials are required to produce biodegradable plastic with excellent characteristics. The production stages of biodegradable plastics include mixing, heating, and casting. The starch-based biodegradable plastic that can apply to an environmentally friendly packaging material has an excellent opportunity developed in Indonesia.</p><p>Keywords: Starch, sago, cassava, biodegradable plastics, production technology</p><p> </p><p><strong>Abstrak</strong></p><p>Plastik merupakan bahan pengemas yang banyak digunakan namun berdampak buruk bagi lingkungan karena sulit terdegradasi di alam.

Negative Impacts

Fossil oil prices are soaring steeply due to the depleting petroleum raw materials. Extensive research has been carried out around the globe to develop efficient processes that can replace oil-derived polymers (conventional plastic) with bio-based polymers that originate from renewable resources. Fossil-oil based plastic products take decades to degrade, leading to the unwanted accumulation of plastic waste that can be seen all around. Further, greenhouse gases emission occurs during the production and destruction of synthetic plastic. Therefore, plastic waste has become a massive threat to the biosphere and needs to be addressed immediately. To overcome this issue, a new type of plastic can be produced from bio-resources that can fulfill even the energy demand in today's world. This new form of plastic must be accommodated fast in daily life, considering the range of applications of plastics. Biodegradable plastics made from renewable raw materials can retain all the benefits of petroleum-based plastic without having any negative impacts on the environment. Bioplastics are not toxic in nature and can easily decay back into carbon dioxide via degradation. The products made from bioplastics may be commercialized, considering their superior properties over conventional plastic. The discovery and implementation of plastic made from renewable raw material resources could be a giant leap into the sustainable future.

The work carried out focuses on the importance and characteristics of bioplastics, which is why the bibliographic sources consulted recall that the plastic manufactured from biopolymers has been increasing due to its practicality and in supporting the reduction of pollution of solid waste worldwide. Viable alternatives are currently being sought to replace packaging and coatings made from non-renewable raw materials, as these cause millions of tons of waste each year, damaging the environment. The production process of biodegradable plastics has a certain resemblance to the production of conventional plastics, it consists of a mixer of raw materials with additional components, for a subsequent blowing and sealing, passing through a quality control. One of the problems with conventional plastics is that they are manufactured from raw materials obtained from non-renewable resources, which each day becomes scarcer and therefore more expensive. Also the problem of persistence in the medium for very long times, which cause them to occupy space in sanitary landfills, which are causing problems in the country due to lack of space.

Ethylene glycol and propylene glycol are important representatives of polyols. On an industrial scale, they are obtained from petrochemical raw materials. Within a decade, significant efforts were made for the producing of polyols from biologically renewable raw materials - carbohydrates. The general trend for carbohydrate hydrogenolysis includes application of liquid-phase process with the use of modified metal-oxide catalysts, at 120-120 ° C and pressure of 3MPa or above. So high pressure is used for the reason to increase hydrogen solubility, and also due to the high partial pressure of low boiling solvents. We supposed that usage of high boiling solvents could allow hydrogenolysis to be performed at the lower pressure. Ethylene glycol and propylene glycol are of particular interest as such kind of solvent since they are both the main products of glucose hydrogenolysis. In this work, the process of hydrogenolysis of glucose and fructose over Cu / MgO-ZrO2 catalyst have been studied at temperature range of 160-200 °C and a pressure of 0.1-0.3 MPa in a flow reactor. The solvents were simultaneously the target products of the reaction - ethylene glycol and / or propylene glycol. Gas chromatography and 13C NMR were used for the reaction products identification. It was found that the solubility of glucose in propylene glycol is 21 % by weight, and in ethylene glycol 62% by weight. It was pointed out that the process of hydrogenolysis can take place at a pressure close to atmospheric. Under these conditions, the conversion of hexoses reaches 96-100 %. The reaction products are preferably propylene glycol and ethylene glycol. The total selectivity for C3-2 polyols is 90-94 %, that is higher than in the hydrogenolysis of glucose in aqueous solution.

The article deals with issues of monitoring, planning, organizational and technical support, economic regulation and improving the efficiency of the infrastructure for processing, recycling and disposal of waste, resource conservation and management of secondary resources, their use as secondary raw materials for production, services, work and power generation. The Russian Federation has significant potential for economic growth due to the efficient use of secondary resources from billions of tons of generated production and consumption waste annually. These ecologically unsafe anthropogenic objects can be characterized as a source of valuable renewable raw materials, material and fuel and energy resources. However, the scale and level of use of various types of secondary resources are characterized by considerable unevenness and depend on the demand for secondary raw materials, the resource value of the waste, the environmental situation arising from treating them as environmental polluters, on the real economic conditions that determine the profitability of each specific type. economic activities that use secondary resources for the manufacture of products, works, services, energy production. The methods of monitoring the industry for the treatment, disposal and disposal of waste are: information-analytical, information-statistical, sociological, geo-information. The legal status of the monitoring system of the industry for the treatment, disposal and disposal of waste is determined by the limitations of its functionality within the framework of the goals and objectives facing it.
