Int"od$ction Plastic pollution is one of the ma'or pro#lems that people $eal (ith re)ar$in) soli$ (aste. It involves the accumulation of plastic pro$ucts in the environment that affects human an$ (il$life #y $e)ra$in) the livin) con$itions of their environments an$ in result, them as (ell. Philippines ran*e$ thir$ hi)hest plastic )enerator in +sia after China an$ In$onesia in the year 2-. /-0 Davao City pro$uces an avera)e of -1. tons of (aste per $ay an$ five percent of these (astes are har$ plastics. /20 Plastic re$uction efforts have #een $one in some areas aroun$ the (orl$ (hich aims to lessen plastic consumption an$ pollution an$ promote recyclin) of plastics. 3he School of En)ineerin) an$ +rchitecture of the +teneo $e Davao niversity envisions its concern to(ar$s the prevention of the $e)ra$ation of the environment throu)h the initiative of the Center of %ene(a#le Ener)y an$ +ppropriate 3echnolo)ies 5C%E+3e6 (oul$ li*e to respon$ to the pro#lem of plastic (astes an$ to promote recyclin) of plastics (astes. 3hrou)h this, the research aims to respon$ to the university7s mission an$ vision (ith emphasis on "au$ato SI, as responsi#le ste(ar$s of  our home. Ob+ecti'es of t!e st$dy 3he o#'ective of the stu$y is to fa#ricate an$ test a shre$$er for the mini plastic recyclin) plant (hich is capa#le of supplyin) the recyclin) plant (ith sufficient reusa#le materials for mol$in) of usa#le items.

Significance of t!e st$dy 3he stu$y also aims to increase a(areness for plastic recyclin) to usa#le materials in the +teneo community as part of

Plastic shre$$in) is a very important part of recyclin) plastics. Plastic shre$$in) itself is very tric*y $ue to the $ifferent types of plastics as (ell as its )eometric characteristics. 9or the reasons a#ove, it is important to $esi)n a shre$$er #ase$ on the type of plastic to #e shre$$e$. /0 Plastic recyclin) in one of the fastest )ro(in) mar*ets cause$ #y scarcity of resources an$ increasin) ener)y costs. 3here are a lot of possi#ilities for the $aily plastic (astes (e pro$uce to #e reuse$. 3he #est e8ample is the PE3 #ottle (hich can #e recycle$ to yarns an$ fi#ers for the te8tile in$ustry, or fuel for #oilers since they have a hi)h calorific value.
