AbstractThis paper presents a recent study on recycling poly-ethylene-tetraphylate (PET), known as plastic waste material in Ghana, to wealth. Composites were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plastic-coated aggregates. The composites produced were reinforced with 4.5 wt%, 9.0 wt%, 13.6 wt%, and 18.0 wt% PET. Mechanical properties of the fabricated composite samples were studied with a Universal testing machine for optimization. The work demonstrated that shredded PET plastic waste material acts as a strong binding agent for bitumen that can improve on the shelf life of the asphalt. From the results, 13.6 wt% concentration of PET was shown to experience the maximum compressive strength and flexural strength. Besides, water resistance was shown to increase with PET concentrations/weight fraction. From the data characterized 13.6 wt% of PET plastic gives the optimum plastic concentration that enhances the rheological properties of bitumen. The implications of the result are therefore discussed for the use of 13.6 wt% PET in road construction.

We are facing a lot of environmental issue right now. One of the environmental problem is household and industrial waste such as plastic. Plastic waste is becoming a widely recognised environmental problem. The government of Samarinda has been banned plastic bags in grocery stores in order to reduce plastic waste as determined by Mayor Regulation No. 8 of 2019. Lots of people are looking for reusable shopping bag. One of the alternative to plastic grocery bag is burlap bag. The traditional market sellers often sell their grain in burlap sacks and may be willing to give away the unusable sacks. Burlap is very useful and has many specific application, like grocery bag and pouch. Burlap grocery bag can be adorned with patch, embroidery and beads. The aim of community service is to teach housewives to design and apply patch onto the burlap grocery bag, as traditional market waste, in order to increase the value of product. The result of the class is : improved their skill in designing and creating patch on burlap bag. It is hoped that the class will support the potential of creativity industry by reusing the waste material.

Abstract This paper presents an exergy-based sustainability analysis of manufacturing roof tiles from plastic waste in Uganda. This work focuses specifically on the developing country context and on utilizing waste material. A summary of the current Ugandan plastic waste situation, environmental and health issues associated with plastic waste, current means of recycling plastic waste into new products, and an analysis of the Ugandan roofing market is presented. The total exergy consumed to produce one batch of 75 tiles is over 240 MJ, the potentially recoverable exergy is nearly 17 MJ (8% of consumed exergy), and the realistic recoverable exergy is over 6.4 MJ (nearly 3% of consumed exergy). Recycling plastic waste into roof tiles saves a net 188 kg of CO2 from entering the atmosphere per batch when compared with open burning. If all of Kampala’s plastic waste was converted to roofing tiles, nearly 560 tonnes of CO2 could be saved per year.

Shoot Emergence

Plastic waste material continues to present environmental challenges throughout the world.  Of greatest concern is their disposal in agricultural soils where they interfere with soil fertility due to its inability to decompose fast.  Specifically, the research examined under experimental conditions the crop germinative emergence of (Zea mays L.) and finger millet (Eleusine coracana (L.) Gaertn) as affected by plastic waste material commonly disposed in urban and rural environments of Kenya.  The plastic types were identified by their thickness of 30 microns. The experiment was laid out in a 2 by 1 Randomized Block Design (Latin Square) with two replicates in plots each measuring 1m x 1m.  The data collected involved determination of emergence percent cover. The date of planting was noted and records were taken from the day first shoot emergence was observed in controls for 10 days.  Percent emergence measurements was done for at least 10 days and this involved taking of vertical photographs of each plot from the day first shoot emergence was observed in controls.  Assumptions of normality were found to be satisfactory and the set hypotheses were supported by the results. In the overall, there were significant differences (P<0.05) between E. coracana planted in soils mixed with 6 microns thick plastic material and the ones planted in controls. The EPC mean for the E. coracana planted in soils mixed with 30 microns thick plastic material was 25.78%, while controls had 75.58%.  There were significant differences (P<0.05) between Z. mays in soils mixed with 6 microns thick plastic material and the ones planted in controls. The EPC mean for the Z. mays planted in soils mixed with thick plastic material was 41.52%, while that of control groups was 86.18%.  In conclusion, there were a significant difference (P<0.05) in effects of 6 microns’ thick plastic material on germinative emergence of the two food crops, that is; E. coracana and Z. mays and hence the study recommends that, plastic waste material of any thickness should be avoided on farmlands where Z. mays and E. coracana are grown.
