Cumulative Energy Demand

The environmental impacts of five waste management scenarios for polylactic acid (PLA)-based bioplastics and food waste were quantified using life cycle assessment. Laboratory experiments have demonstrated the potential for a pretreatment process to accelerate the degradation of bioplastics and were modeled in two of the five scenarios assessed. The five scenarios analyzed in this study were: (1a) Anaerobic digestion (1b) Anaerobic digestion with pretreatment; (2a) Compost; (2a) Compost with pretreatment; (3) Landfill. Results suggested that food waste and pretreated bioplastics disposed of with an anaerobic digester offers life cycle and environmental net total benefits (environmental advantages/offsets) in several areas: ecotoxicity (−81.38 CTUe), eutrophication (0 kg N eq), cumulative energy demand (−1.79 MJ), global warming potential (0.19 kg CO2), and human health non-carcinogenic (−2.52 CTuh). Normalized results across all impact categories show that anaerobically digesting food waste and bioplastics offer the most offsets for ecotoxicity, eutrophication, cumulative energy demand and non-carcinogenic. Implications from this study can lead to nutrient and energy recovery from an anaerobic digester that can diversify the types of fertilizers and decrease landfill waste while decreasing dependency on non-renewable technologies. Thus, using anaerobic digestion to manage bioplastics and food waste should be further explored as a viable and sustainable solution for waste management.

The organic fraction (mainly food waste) is typically the most abundant of the separately collected waste streams. The research aims at investigating the influence of different types of collection bag on the environmental performances of the food waste management chain in Italy. A comparative life cycle assessment (LCA) between two alternative systems based on paper or bioplastic collection bags was carried out. It included the collection bags manufacturing and distribution, their use at the household, the transportation of collected food waste and its subsequent anaerobic digestion, including the valorisation of useful outputs and the management of residues. The two systems were modelled mainly with primary data related to the current management system and to tests performed on bags. The LCA was performed with two different modelling approaches applied in the environmental product declaration (EPD) system and in the product environmental footprint (PEF) studies, respectively. In the scenario representing the average conditions, higher environmental impacts are shown by the use of bioplastic bags compared to paper ones with the EPD approach (+257%/+576%). With the PEF approach, the differences between the two systems are lower (−55%/+133%). Moreover, paper bags could allow for further impact reductions assuming a decrease of the food waste collection frequency, allowed by higher weight losses and a lower generation of leachate and odour during the household storage.

Mengembalikan sampah makanan (SM) sebagai kompos ke lahan pertanian dianggap sebagai salah satu opsi terbaik untuk memastikan keberlanjutan pertanian bagi kota-kota yang bergantung pada sektor pertanian sebagai tulang punggung dari modal pembangunan mereka seperti Kota Pagar Alam. Sementara pengomposan SM mudah dilakukan dalam skala kecil, membuat kompos dari SM di tingkat kota merupakan tugas yang memberatkan yang berarti perlu pengelolaan sampah yang tepat. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan kerangka kerja manajemen SM untuk Kota Pagar Alam berdasarkan metodologi Life Cycle Assessment. Variabel yang dimasukkan dalam kerangka adalah struktur usia rumah tangga, kebiasaan makan, pengeluaran makanan per kapita, penghasilan kepala rumah tangga, praktik belanja, perilaku pemisahan sampah dan sikap pada barang bekas. Temuan menunjukkan timbulan SM dipengaruhi oleh struktur usia rumah tangga serta pengeluaran makanan. Jumlah anggota rumah tangga di bawah usia lima tahun memiliki pengaruh lebih besar terhadap timbulan SM (Exp β = 5,04) daripada pengeluaran makanan per kapita (4,37) atau jumlah anggota rumah tangga yang berusia lima tahun atau lebih (2,16). Alasan mengapa rumah tangga tidak melakukan pemilahan sampah adalah terlalu malas, memiliki kesenjangan pengetahuan dan kurangnya fasilitas. Temuan menyarankan otoritas lokal untuk mengintegrasikan pengumpul sampah informal ke dalam sistem pengelolaan sampah dan menciptakan permintaan pasar kompos untuk mengatasi hambatan sosial yang ada. Studi ini menyimpulkan bahwa dimasukkannya struktur usia rumah tangga dan perubahan perilaku masyarakat dalam kerangka kerja manajemen SM sangat penting.
