Petroleum-based plastic has been widely used in many industries. However, it takes hundreds of years to degrade and causes widespread pollution to our environment. These problems led to the invention of bioplastics, which were comprised of natural biopolymers made from starch. The production of bioplastics from food-based starches such as tapioca and corn created competition between food and bioplastic production industries. Hence, this research study focuses on producing bioplastic from microalgae residue, which is a non-food based raw material that uses four different types of plasticizers: glycerol, sorbitol, glutaraldehyde and polyethylene glycol (PEG). Microalgae species for identification were obtained from the fish pond at the University Malaysia of Kelantan, before cultivating the species for 14 days. The microalgae residues were extracted through the centrifugation process. Three species were identified under the light microscope, Chlorella sp., Scenedesmus sp. and Monoraphidium sp. The production of bioplastic involved a manual stirring method using a hotplate magnetic stirrer, followed by drying the bioplastic in an oven at 60 oC. Results obtained showed that sorbitol and glycerol from microalgae are suitable to be used as a plasticizer for the production of bioplastic, however glutaraldehyde and PEG are not suitable. Bioplastics that used PEG and glutaraldehyde became cracked and brittle after the drying process. The characterization of bioplastics includes universal tensile testing machines, Fourier-transform infrared analysis and biodegradability tests being processed//undertaken on glycerol-based and sorbitol based bioplastic. Characterization of bioplastics proved that both glycerol and sorbitol have high potential for applications in daily human life. Bioplastics which used sorbitol as a plasticizer could be used in can be applied the production of plastic goods such as toys and household items due to its good resistance toward stress and minimal flexibility. Meanwhile bioplastics which used glycerol as a plasticizer could be applied to the production of plastic bags and plastic food wrap due to its elastic and flexible nature.

“…The oven dried leaves were grounded with a stain less steel Wiley mill and digested by a dilute sulfuric-salicylic acid and 30% hydrogen peroxide; subsequently total nitrogen was determined by the modified-Kjeldahl method (Jackson, 1958); phosphorus by spectrophotometer and potassium by flame photometer (Jackson, 1958). The nutrient uptake was calculated as the product of the nutrient concentration and dry matter yield of coffee seedling as described by Ibiremo and Akanbi (2016). Accordingly the leaf N, P and K -uptake were obtained by multiplying nutrient concentration of respective parameters by leaf dry matter for each treatment.…”

Nursery experiment was conducted at Haru Agricultural Research Sub Center (HARSC) of Jimma Agricultural Research Center, Western Ethiopia, to investigate dry matter yield and its nutrient uptake of Arabica coffee seedlings under different lime and coffee husk compost rates and establish optimum combination of theseagricul tural inputs that produce seedlings with better dry matter yield for field planting. The experiment was laid out in a factorial experiment arranged in randomized complete block design with three replications. The treatments included four levels of lime (0, 1.6, 3.2 and 4.8 t ha-1) and coffee husk compost (0, 5, 10 and 15 t ha-1). Nutrient uptake and dry matter yield data of coffee seedlings were collected and subjected to analysis of variance using SAS package and treatment means were compared at 0.05 probability using Duncan’s Multiple Range Test. The results revealed that lime and coffee husk compost rates significantly (P< 0.01) affected NPK uptake and total dry matter yield of coffee seedlings. The highest NPK uptake and total dry matter yield of coffee seedling were obtained from the application of 15 t.ha-1 coffee husk compost and combined lime and coffee husk compost at the modest levels of 3.2 t.ha-1 lime and 10 t.ha-1 coffee husk compost with a nonsignificant variation. From the study, it can be concluded that application of 15 t.ha-1 coffeehusk compost or combining 10 t.ha-1 of coffee husk compost and 3.2 t.ha-1 of agricultural lime could be a promising alternative amendment for acid soil management and production of vigorous coffee seedlings with high nutrient uptake and high dry matter yield in HARSC areas.
