“…The authors concluded that cellulose performed better, but WP-N was more economically viable. In another work, recycled PP was mixed and hot-pressed with printed and unprinted WP to determine the effect of the ink on the material properties [ 70 ]. The presence of ink generated better interfacial interaction between the polymer and the filler due to its iron oxide content, thus improving the composite’s mechanical strength (tensile 37.9% and flexural 17.8%), tensile modulus (38.5%), and water resistance (25.5%).…”

This review focuses on polymeric waste-paper composites, including state-of-the-art analysis with quantitative and qualitative discussions. Waste paper is a valuable cellulose-rich material, produced mainly from office paper, newspaper, and paper sludge, which can be recycled and returned to paper production or used in a new life cycle. A systematic literature review found 75 publications on this material over the last 27 years, with half of those published during the last five years. These data represent an increasing trend in the number of publications and citations that have shown an interest in this field. Most of them investigated the physicomechanical properties of composites using different contents of raw waste paper or the treated, modified, and cellulose-extracted types. The results show that polyethylene and polypropylene are the most used matrices, but polylactic acid, a biodegradable/sourced polymer, has the most citations. The scientific relevance of waste-paper composites as a subject includes the increasing trend of the number of publications and citations over the years, as well as the gaps identified by keyword mapping and the qualitative discussion of the papers. Therefore, biopolymers and biobased polymers could be investigated more, as well as novel applications. The environmental impact in terms of stability and degradation should also receive more attention regarding sustainability and life cycle analyses.

“…Nowadays, it has become attractive to use natural cellulose fibers instead of synthetic fibers in composite materials due to their environmental properties and low costs. Besides various cellulose fibers, wood flour, 1 sawdust, 2,3 paper mill sludge, 4,5 old newspaper [6][7][8] and cellulose wastes such as sugar cane, 9 corn cob, 10 straw 11 are used as filling materials in plastic composites. One of the most significant recyclable components of the solid waste stream is old newspaper.…”

The study investigates changes in the mechanical, thermal, morphological and physical properties of recycled low density polyethylene (LDPE) composites made with percentages (10 wt%, 20 wt%, 30 wt.%) of old newspaper fiber (ONF) and waste engine oil (WEO) (1 wt.%). The composites were manufactured by a single screw extruder. Adding WEO up to 20 wt% of ONF had a positive effect on the flexural properties, while the incorporation of WEO up to 10 wt % of ONF showed an affirmative effect on the tensile properties of the composites. The highest flexural strength was achieved in A3 (13.19 MPa) and B3 (12.3 MPa) samples for ONF added composites and ONF/WEO composites, respectively. Adding to the WEO decreased the water absorption values of the recycled low density polyethylene composites. Differential scanning calorimetry analysis showed that the addition of 1% WEO, the crystallinity of the composites decreased to about 30%. In the light of the results, the WEO could be successfully used with old newspaper in a polyethylene matrix.Highlights The highest tensile strength was achieved in the B3 sample (with WEO). The highest flexural strength was achieved in the B3 sample (with WEO). The highest tensile was obtained from the A3 sample (without WEO). The highest flexural strength was obtained from the A3 sample (without WEO). The crystallinity of the composites decreased to about 30%.

“…Pesman ve Güleç (2019) atık ofis ve gazete kâğıdı-atık PP kompozitleri üzerine yaptıkları çalışmada gazete kâğıdı lifi kullanılan örneklerde kontrole göre eğilme direncinin 28.3 MPa'dan 25.1 MPa'ya düştüğünü belirlemişlerdir. Bu sonuçlar bu çalışmadaki sonuçlar ile benzerlik göstermektedir[23].Şekil 5'de kompozitlerin eğilmedeki deformasyon oranları görülmektedir. Grafiklerden deformasyonun atık gazete kağıdı lifi ilavesiyle düştüğü görülmektedir.…”

“…%10 atık kağıt lifi ilavesi ile direnç değeri yaklaşık 19 MPa'ya kadar düşmüştür. Aynı atık PP'nin kullanıldığı bir başka çalışmada atık PP'nin çekme direnci 17.2 MPa olarak ölçülmüş ve %50 atık gazete kağıdı ile 10.8-14.9 MPa aralığına kadar düşüş gözlenmiştir[23].Şekil 6. Lif-PP kompozitlerinin çekme dirençleriÇekmede elastikiyet modülünde durum biraz daha farklı olup dolgu oranının artışı ile birlikte elastikiyet modülü her iki grup için %20 lif oranına kadar artmış %30 oranında ise bir miktar azalmıştır.…”

Bu çalışmada lignoselülozik dolgu maddesi olarak atık gazete kâğıdı lifi, bitkisel atık yağ kullanılmış, polimer olarak da geri dönüştürülmüş polipropilen kullanılmıştır. Atık gazete kâğıdı öğütülüp ve yaklaşık 24 saat boyunca 60˚C˚'de kurutma fırınında bekletildikten sonra %10, %20 ve %30 oranlarında geri dönüştürülmüş polipropilen ile karıştırılmıştır. Atık bitkisel yağ ise %2.5 oranında ilave edilmiştir. Karışımlar 170°C,175°C,180°C,185°C ısı kademelerinde ayarlanmış olan ekstrüzyon makinasına konulmuştur. Ekstrüzyon yöntemiyle üretilen kompozitlerin mekanik ve termal özellikleri belirlenmiştir. Atık gazete kağıdı lifi oranının ilkin eğilme mukavemetini azalttığı, daha sonra ise arttırdığı gözlenmiştir. Termal özelliklerde atık bitkisel yağ kullanımının olumlu etkisi olup ısıl direnci arttırmıştır. DSC analiz sonuçları incelendiğinde, atık gazete kağıdı lifinin kristalenliği arttırdığı sonucuna varılmıştır. Bu çalışma ile tümüyle atık olan bileşenlerin kompozit üretiminde kullanılabilir olduğu ve vaks gibi atık bitkisel yağların kullanılabileceği sonucuna ulaşılmıştır.
