“…From an environmental perspective, the industrial implementation of the current study could assist in tackling waste accumulation issues in Europe, especially Poland. Paper and cardboard waste comprised approximately 15% of municipal solid waste from 2012 to 2017, whereas plastics resamples were 18%, and this data is expected to witness a considerable rise in the next years [ 32 ]. The chemical composition of corrugated cardboard showed that our samples contained 58.2% cellulose, 9.6% hemicellulose, 10.0% lignin, and 22.2% other components, which were in good line with another investigation [ 33 ].…”

Bioplastics are contemplated as remarkable substitutes for conventional plastics to accommodate green technological advancements. However, their industrial production has not been fully implemented owing to the cost of carbon resources. From another perspective, valorizing different paper mill wastes has become a prominent research topic. These materials may serve as an affording sustainable feedstock for bioplastic production. Adjustment of cardboard waste hydrolysate as suitable fermentation media for production of bacterial polyhydroxyalkanoates (PHAs) has been investigated. Cardboard samples were defibered and dried before enzymatic hydrolysis. The enzymatic degradation of commercial cellulase was monitored over 15 days. Interestingly, 18.2 ± 0.2 g/L glucose yield was obtained from 50 g cardboard samples using a 1.5% (v/v) enzyme concentration. The samples exhibited maximum weight loss values of 69–73%. Meanwhile, five soil samples were collected from local sites in Lodz, Poland. A total of 31 bacterial isolates were screened and cultured on Nile blue plates. Analysis of the 16S rRNA gene sequence of the most potent producer revealed 100% similarity to Bacillus mycoides. Cardboard hydrolysates whole medium, modified MSM with cardboard hydrolysate and nitrogen depleted MSM with cardboard hydrolysate were utilized for PHA production, followed by PHA productivity and cell dry weight (CDW) estimation compared to glucose as a standard carbon source. An impressive PHA accumulation of 56% CDW was attained when the waste hydrolysate was used as a carbon source. FTIR and NMR analysis of the isolated PHA indicated that functional groups of the polymer were related to PHB (polyhydroxybutyrate). Thermal analysis demonstrates that PHB and PHB-CB (PHB produced from cardboard hydrolysate) have degradation temperatures of 380 and 369 °C, respectively, which reflect the high thermal stability and heat resistance compared to the same properties for a standard polymer. This is the first demonstration of full saccharification of corrugated cardboard paper waste for high-level production of PHA. In addition, the attained PHB productivity is one of the highest levels achieved from a real lignocellulosic waste.

Orlescu and Costescu [28] was also showed, domination share of biodegradable waste in Romania and Przydatek [29] also showed high contribution of glass in Poland (26%). The contribution of the last type waste in Bacau County was lower level of 5%.…”

In recent years, technology and innovation have also reached the field of waste. They provide an excellent opportunity to improve policies aimed at minimizing waste generation and achieving resource efficiency. However, the degree of introduction of innovative equipment and practices varies significantly from one territory to another. The comparative analysis carried out on within 5 years, showed noticeable changes in the counties in Romania and Poland initiated by the EU and national legislation which indicated an increase in the amount of waste recovered. However, the achieved efficiency of limiting the deposited waste was different at the level of exceeding 70 % and higher of 0.10 kg an average indicator of waste accumulation per capita in Bacau County. Two counties mainly difference composition of municipal waste with predominance of biodegradable waste (60 %) in Bacau County and glass waste (35 %) in Nowy Sącz County with raw material properties. Differences were also noticeable in the case of hygiene fees with exceed of average value 20 EUR in Nowy Sącz County. The gradual increase in the amount of recycled waste and covering all residents with hygiene services should be considered beneficial which indicates an improvement in environmental awareness.

“…The changing consumption patterns and growth in prosperity as well as rapid urbanisation have also contributed to the increases in per capita generation of waste, of late (World Bank, 2021). Meanwhile, the lack of places for treatment and disposal of waste have also led to a rise in the heaps of wastes in many countries (Przydatek, 2020).…”

PurposeThe paper focuses on Malaysia's huge waste challenges and how circular economy practices can turn that into increased and sustained economic growth.Design/methodology/approachPublished official reports on the country's sustainable development initiatives, policy statements from local authorities and government agencies as well as UN bodies and other secondary materials were sourced for this article.FindingsThe paper finds that Malaysia's waste can be used in generating wealth for the country if and when a conscious effort is made towards establishing a sound circular economy in the country. It also sees enormous opportunities that exist for cooperative models of social enterprises and business innovations.Originality/valueThe paper details the numerous policies and initiatives that the Malaysian government has embarked upon in recent times and scrutinises them to decipher the direction of country's bid for sustainable development. It also carries details of what can be done to achieve circularity as well as the benefits that can accrue from that.
