Food waste is daily generated in significant amounts around the world, implying the depletion of natural resources and the emergence of environmental pollution issues if discarded without valorization or utilization. In this regard, food waste management poses an important challenge in the circular society. Based on the official statistics and the national laws and regulations database in Taiwan, this study analyzed the on-line reporting amounts of collected food waste since it has been officially designated as one of the mandatory recyclable wastes. Furthermore, the regulatory measures for promoting food waste utilization in Taiwan were addressed to valorize it for the production of value-added resources and also prevent the spread of African swine flu. It showed that the collected amounts of food waste from residential and commercial sectors in Taiwan significantly increased from about 168,600 metric tons in 2003 to the maximal amount (i.e., 834,500 metric tons) in 2012, reflecting the regulatory promulgation and promotional measures. Based on the joint efforts by the central governing authorities (including the Environmental Protection Administration, the Council of Agriculture, and the Ministry of Economic Affairs), this study also examined the regulatory promotions for utilizing food waste as an available resource for the production of value-added resources (i.e., organic fertilizer, pig feed, and bioenergy). Through the central governing authority, local governments, and private recyclers, about 2000 metric tons of food waste in Taiwan was recycled every day, which can not only mitigate the pressure on waste incineration and disposal systems, but also conform to the trends of environmental sustainability and circular bioeconomy. Therefore, the Taiwan government is currently supporting the establishment of anaerobic digestion and aerobic composting plants for turning food waste into organic fertilizers and biogas-to-electricity because they have been evaluated as the best options of food waste valorization.

<p>As a region with the largest oil palm plantations in Indonesia, Pelalawan Regency is highly potential to develop a program of oil palm-cattle integration. Pelalawan has implemented the program legitimated by Regent Decree Number KPTS./524/Disnak/2012/472 regarding Zoning Regulation on the development of Oil Palm-Cattle Integration. The program of oil palm-cattle integration itself has been the basis for the Decree of the Minister of Agriculture Number 105 Year 2014 regarding the Integration of Oil Palm Plantation and Beef Cattle Farming. Moreover, the integration system of oil palm-cattle gives a lot of benefit to farmers, for example the utilization of manure as organic fertilizers could reduce farmer’s expenses for chemical fertilizers and the cattle can be an asset for them. Products made from the integrated program are solid manure, liquid organic fertilizer, fodder, biogas, and beef. To improve the competitiveness of those activities, we can analyze the value chain which includes product design, inbound logistics, operations, outbound logistics, marketing, sales, services and supporting activities. By using a value chain analysis, this study aims to provide recommendations for strengthening programs which could be implemented to improve the value-added of the products.</p><p> </p><p>Keywords: oil palm-cattle integration, value chain, value-added, industrial cluster</p>

Konsep pengelolaan sampah telah lama berubah dari pemusnahan atau pembuangan menjadi pemanfaatan. Namun konsep ini belum diikuti dengan langkah nyata oleh pemerintah. Kepedulian terhadap kelestarian lingkungan telah mendorong beberapa kelompok masyarakat, lembaga atau institusi untuk bergerak aktif dalam pemanfaatan sampah. Universitas Andalas sebagai lembaga pendidikan tinggi terkemuka di Pulau Sumatera sudah saatnya mengambil peran aktif dalam melakukan pengelolaan sampah yang berwawasan lingkungan. Timbulan sampah yang cukup besar yaitu 28 m3/hari pada tahun 2012, yang diproyeksikan akan menjadi 34 m3/hari atau 9 ton/hari pada tahun 2017, menawarkan potensi cukup besar untuk dimanfaatkan. Pada tahun proyeksi 2017 dari total timbulan sampah, 26,6 % (2,4 ton/h) adalah sampah makanan, 9,8 % (0,9 ton/h) adalah sampah penyapuan taman/jalan, 30,0 % (2,7 ton/h) adalah sampah plastik, 25,3 % (2,3 ton/h) adalah sampah kertas, 1,5 % (0,1 ton/h) adalah sampah kaleng, logam dan besi dan 6,9 % (0,6 ton/h) adalah sampah lain-lain (tekstil, karet, kayu, kaca dll). Dari total sampah makanan dan penyapuan halaman/jalan, 33,7 % berpotensi untuk menghasilkan kompos sekitar 1,2 ton/hari, 2,1 % (0,2 ton/h) dapat dimanfaatkan untuk proses biogas dan sisanya 0,5 % (0,05 ton/h) ditimbun di TPA. Sampah plastik dan kertas sebesar 55,3 % dapat dimanfaatkan kembali atau dijual ke PT. Semen Padang sebagai tambahan bahan bakar unit kiln. Dari 1,5 % sampah kaleng, logam dan besi, 1,3 % dapat dimanfaatkan kembali atau dijual ke pihak ketiga sedangkan sisanya yang hanya sebesar 0,02 ton/h dibuang ke TPA Air Dingin. Selanjutnya, sisa timbulan sampah sebesar 6,9 % yang berupa sampah tekstil, karet, kayu, kaca dan lain-lain dapat dimanfaatkan sebagai bahan bakar alternatif pada kiln PT. Semen Padang. Jika konsep ini dapat dilaksanakan, maka Universitas Andalas dianggap mampu melakukan pemanfaatan sampah hingga 99,3 %. Kata kunci: Pemanfaatan sampah, kelestarian lingkungan, pengelolaan sampah yang berwawasan lingkunganABSTRACTManagement of solid waste has been changed from dumping to utilization. However, this concept is not fully applied yet by the government. Environmental sustainability awareness has been stimulating some community groups and institutions to actively involve in waste utilization. Andalas University as a leading higher education institution in Sumatera Island must give active contributions in solid waste management for environmental sustainability. Solid waste generation of 28 m3/day, which is projected to be 34 m3/day or 9 ton/day in 2017, offers huge enough potency for utilization. From the total solid waste generation in 2017, 26.6 % (2.4 ton/day) is food waste, 9.8 % (0.9 ton/day) is garden/road waste, 30.0 % (2.7 ton/day) is plastic waste, 25.3 % (2.3 ton/day) is paper waste, 1.5 % (0.1 ton/day) can, metal and iron waste and 6.9 % (0.6 ton/day) is micellaneous waste (textile, rubber, wood, glass etc). 33.7 % of food waste and garden/road waste may be recycled to compost around 1.2 ton/day, 2.1 % (0.2 ton/day) may be utilized for biogas and the rest 0.5 % (0.05 ton/day) is sent to TPA Air Dingin. Plastic waste and paper wich is 55.5 %, may be used for additional fuel for kiln unit of PT. Semen Padang. From 1.5 % can, metal and iron waste, 1.3 % may be reused or sold to third party while the reset (only 0.02 ton/day) must be disposed to TPA Air Dingin. Furthermore, the rest of waste generation account for 6.9 % composed of textile, rubber, kayu, kaca dll may be used as alternative fuel for kiln PT.Semen Padang. If this concept is practiced, then the Andalas University is considered capable of utilizing their waste up to 99.3 %.Keyword: Utilization solid waste, environmental sustainability, management of solid waste

Changes in soil organic matter (SOM) are slow and difficult to monitor, usually apparent after few decades. Recent changes in the agriculture had its influence on soil, including the soil organic matter content. About 60% of soil in Nepal now have low organic matter content. Agriculture Perspective Plan (APP) was focused more on the concept of green revolution to increase the chemical fertilizer inputs, however, the scenario is changing. Use of organic fertilizers is promoted extensively by government and different organizations with a target of increasing SOM content from 1.92% in 2015 to 4% by 2035. This paper aims at analysing the current status, targeted goal and the challenges faced in the augmentation of the soil organic matter using data available. Achieving this target requires an addition of extra 2.244 ton/ha of organic matter on a yearly basis for 20 years. The average amount of organic matter (2.5-3 ton/ha) applied is lesser than a single season grain harvest. 4.69% of sites had high soil organic matter in fiscal year 075/76 which slipped to 2.64% in 2076/77. The sites with low soil organic matter increased from 12.73% to 15.31%. The causes behind the SOM decline varies according to different agro-ecological zones like soil erosion, residue burning, imbalanced fertilizer use, defective FYM production etc. Findings suggest precise technologies required to be adopted to tackle with the different niche specific causes of soil fertility decline. Despite the complete nutrient content, bulky nature of organic fertilizers sets a major drawback regarding their transportation, distribution and commercialization. Government of Nepal is promoting organic fertilizer use by subsidizing their production cost by 50%. Following integrated nutrient management (INM) techniques, sustainable soil management practices (SSMP) and promotion of use of locally available resources can play a huge role in making the technology sustainable to the farmers.

AbstractIn recent times, research attention is focusing on harnessing agricultural wastes for the production of value-added products. In this study, the valorization of Carica papaya (Pawpaw) fruit peels was evaluated for the production of quality organic fertilizer via anaerobic digestion (AD) while the effects of the fertilizer on maize crop were also assessed. Pawpaw peel was first pretreated by thermo-alkaline methods before AD and analyses were carried out using standard methods. The resulting digestate was rich in nutrients and was dewatered to form solid organic fertilizer rich in microbes and soil nutrients. When applied to maize plants, organic fertilizer showed a better effect on plant traits than NPK 15–15–15 fertilizer and without fertilizer application. These were more pronounced at mid to high organic fertilizer applications (30-to-60-kg nitrogen/hectare (kg N/ha)) rate. Comparison between the values obtained from the field experiments reveals that the organic fertilizer showed better performance in all parameters such as the number of leaves, leaf area, plant height, stem girth, total shoot, and root biomass, and length of the root. However, the chemical fertilizer outperformed all the organic fertilizer applied rates in the average highest size of the corn ear by 1.4%. After harvesting, nutrient elements were found to have bioaccumulated in plant organs (leaves, stem, and root) with the highest values being 29.7 mg/L for nitrogen in the leaf and this value was reported from the experiment with 50 kg N/ha. For phosphorus and potassium, the highest concentrations of 7.05 and 8.4 mg/L were recorded in the plant’ stem of the experiment with 50 kg N/ha. All the treated soils recorded an increase in values of all nutrient elements over the control with the highest values recorded in the experiment with 60 kg N/ha. In soil with 60 kg N/ha, the nitrogen, phosphorus, and potassium increased by 28, 40, and 22% respectively over the chemical fertilizer applied experiment while different levels of increases were also recorded for all other macro and microelements in all the experiments. Thus, agricultural practices by using anaerobic digestates as organic fertilizers is a sustainable method to overcome the dependence on inorganic fertilizers high rate.

Despite numerous discussions between scholars and policymakers, food waste (FW) remains a great concern. European Union alone discards 88 million tons of edible food annually, and when energy, inputs from technosphere and nature, labour, waste management of edible as well as inedible parts are assessed, it amounts to significant environmental and economic impacts. Additionally, food waste is considered a social problem and a matter of food security. Since food waste is a problem of the whole foodstuff supply chain, a holistic approach for its management must be taken. For this reason, an industrial ecology (IE) concept can provide a systemic approach that might be an interesting solution for tackling issues associated with such a biogenic food waste stream. The application of IE brings novelty to the research, because the IE approach is typically used for heavy industry that is concentrated in close proximity. The idea behind the IE approach is to prevent as much food waste as possible, then exploit homogenous sub-products for value added product (either food product or not), and, eventually, to obtain energy (or value added products) via fermentation and produce organic fertilizers of a great agronomical value. The results of investigation showed that numerous prevention and technological solutions can be applied to reduce environmental impact, and when available practises are coupled with IE elements, it brings the management approach close to natural ones. The key IE elements in the model are dematerialization and industrial symbiosis; however, other elements, such as restructuration of energy systems and policy alignment, are also present. As a result of the model application, an economically sound, zero food waste management could be obtained in a region
