State of the Wetlands in the Lake Simcoe Watershed Ontario Streams Technical Report No
July 2018 State of the Wetlands in the Lake Simcoe Watershed Ontario Streams Technical Report No. 2018-01 Alexander Kissel, Habitat Technician & Alice Choi, GIS Technician, Ontario Streams ontariostreams.ca Summary Wetlands in the Lake Simcoe Watershed are critical to the health of the Lake and its surrounding ecosystem. They cover 18.4% of the surface area around the Lake or 52 847 hectares (ha). About 62.4% of these wetlands have been evaluated using the Ontario Wetland Evaluation System (OWES) Southern Manual. The distribution of wetlands vary with fewer and smaller wetlands on the Oak Ridges Moraine (7.1% of surface area), the Schomberg Clay Plains (5.5%) and the uplands west of the the Lake (10.9 to 12.7%), contrasting with the larger valley and shoreline wetlands in the lowlands around the Lake (25.7%). Small wetlands play an important role particularly in the landscapes where they make up a large portion of the wetlands. A high resolution (15 centimetre pixel) analysis of aerial imagery from 1999/2002 to 2013/2016 for the Lake Simcoe Watershed has shown that many small wetland losses, and the occasional larger ones, add up over this time period to a loss of almost eight square kilometres or 773 ha (1.5% of the total wetland area). This loss is higher than previous estimates using lower resolution (30-metre pixel) satellite imagery which cannot pick out the smaller losses that have a large cumulative impact. The highest losses have been from agriculture (46.4% of all losses), following in descending order by residential (10.5%), peat extraction (10.4%), canals (9.6%), highways/roads (6.6%), industrial/commercial (5.7%), fill (4.6%), dug-out ponds (4.3%), recreation (1.6%) and aggregates (0.3%). -
Analysis of Promotion Policies for the Valorization of Food Waste from Industrial Sources in Taiwan
fermentation Article Analysis of Promotion Policies for the Valorization of Food Waste from Industrial Sources in Taiwan Wen-Tien Tsai * and Yu-Quan Lin Graduate Institute of Bioresources, National Pingtung University of Science and Technology, Pingtung 912, Taiwan; [email protected] * Correspondence: [email protected]; Tel.: +886-8-7703202 Abstract: Growing concern about circular bioeconomy and sustainable development goals (SDGs) for the valorization of food waste has raised public awareness since 2015. Therefore, the present study focused on the promotion policies and regulatory measures for the valorization of mandatory recyclable food waste from industrial sources in Taiwan, including the animal/plant production farms and food-processing plants. According to the official data on the annual statistics during the period of 2015–2019, it showed that the food waste from alcoholic beverage manufacturers (i.e., lees, dregs, or alcohol mash) and oyster farms (i.e., waste oyster shell) accounted for about half (about 250,000 metric ton) of industrial food waste generation in Taiwan. In order to effectively reduce the burdens on incinerators/landfills and their environmental impacts, the central governing agencies jointly promulgated some regulatory measures for promoting the production of biobased products from the industrial food waste valorization like animal feed, soil fertilizer, and bioenergy. These relevant acts include the Waste Management Act, the Fertilizer Management Act, the Feed Management Act, and the Renewable Energy Development Act. In addition, an official plan for building the food waste bioenergy plants at local governments via anaerobic digestion process, which was estimated to be completed by 2024, was addressed as a case study to discuss their environmental Citation: Tsai, W.-T.; Lin, Y.-Q. -

In response, major agencies have set goals to halt this loss and work to restore wetlands to varying degrees of function and area. To aid those agencies, this study was guided by four research questions: (i) Which physical and ecological landscape criteria represent high suitability for wetland reconstruction? (ii) Of common wetland suitability metrics, which are most important? (iii) Can a multi-criteria wetland suitability index (WSI) effectively locate high and low wetland suitability across the Ontario Mixedwood Plains Ecozone? (iv) How do best sites from the WSI compare and contrast to both inventories of presettlement wetlands and current existing wetlands? The WSI was created based on seven criteria, normalized from 0 (low suitability) to 10 (high suitability), and illustrated through a weighted composite raster. -

Moreover, resource recovery from these wastes has become the new focus of wastewater management, to develop more sustainable processes in a circular economy approach. The aim of this review was to analyze current sewage sludge management systems in Scandinavia with respect to resource recovery, in combination with other organic wastes. As anaerobic digestion (AD) was found to be the common sludge treatment approach in Scandinavia, different available organic municipal and industrial wastes were identified and compared, to evaluate the potential for expanding the resource recovery by anaerobic co-digestion. Additionally, a full-scale case study of co-digestion, as strategy for optimization of the anaerobic digestion treatment, was presented for each country, together with advanced biorefinery approaches to wastewater treatment and resource recovery.

International Journal of Environmental Research and Public Health Review Waste Mismanagement in Developing Countries: A Review of Global Issues Navarro Ferronato * and Vincenzo Torretta Department of Theoretical and Applied Sciences, University of Insubria, Via G.B. Vico 46, I-21100 Varese, Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-338-887-5813 Received: 6 March 2019; Accepted: 22 March 2019; Published: 24 March 2019 Abstract: Environmental contamination due to solid waste mismanagement is a global issue. Open dumping and open burning are the main implemented waste treatment and final disposal systems, mainly visible in low-income countries. This paper reviews the main impacts due to waste mismanagement in developing countries, focusing on environmental contamination and social issues. The activity of the informal sector in developing cities was also reviewed, focusing on the main health risks due to waste scavenging. Results reported that the environmental impacts are pervasive worldwide: marine litter, air, soil and water contamination, and the direct interaction of waste pickers with hazardous waste are the most important issues. Many reviews were published in the scientific literature about specific waste streams, in order to quantify its effect on the environment. This narrative literature review assessed global issues due to different waste fractions showing how several sources of pollution are affecting the environment, population health, and sustainable development. The results and case studies presented can be of reference for scholars and stakeholders for quantifying the comprehensive impacts and for planning integrated solid waste collection and treatment systems, for improving sustainability at a global level.

Trabold 1,* 1 Golisano Institute for Sustainability, Rochester Institute of Technology, Rochester, NY 14623, USA; [email protected] (J.T.S.); [email protected] (A.L.L.) 2 New York State Pollution Prevention Institute, Rochester Institute of Technology, Rochester, NY 14623, USA * Correspondence: [email protected]; Tel.: +1-585-475-4696 Received: 8 June 2020; Accepted: 21 July 2020; Published: 24 July 2020 Abstract: Using a commercially available dehydration unit, this study aimed to valorize various food waste streams from different sources in the Rochester, New York area. Dehydration of the food waste collected for the study helped reduce the weight of the feedstock by 70–90%, as the incoming waste streams were relatively wet. The output was materially characterized against end uses such as cattle feed, fish feed, and compost. The results demonstrated that, other than fertilizer, the remaining five end uses (compost, fish feed, cattle feed, pyrolysis, and pelletized fuel) were potentially compatible with varying waste feedstocks based on the parameters analyzed. Fish feed in particular was found to be the most compatible end use, as a number of attributes, including protein, fell within the optimal range of values. Pelletized fuel was also determined to be a viable application, as six out of eight sources of dehydrated food waste had higher heating values above the minimum U.S. standard level of 18.61 MJ/kg. Ultimately, this analysis showed that the composition of the food waste needs to be matched to an end-use application and sale of the product for dehydration to be a worthwhile valorization strategy. -

Healthcare Waste and Extended Producer Responsibility: the Specific Case of E-Medical Equipment
Issue 6, Volume 5, 2011 733 Healthcare waste and extended producer responsibility: the specific case of e-medical equipment Elisabeth Lefebvre, Alejandro Romero, Louis-A. Lefebvre known as product stewardship. We thus analyzed the Abstract — The extended producer responsibility implies more initiatives undertaken by the e-medical equipment than the mere take-back and recycling programs tailored towards the manufacturers to reduce the environmental impacts of their end-of-life management. It requires the producers to design products products when they are manufactured, used and finally that are environmentally friendly during all stages of their life cycle, disposed (when they become obsolete). We will present here namely manufacturing, usage or consumption, and final disposal. In empirical evidence gathered from e-medical equipment particular, it implies that products at the end of their useful life producers located in the US and Canada. The specific should be easily dismantled, recovered, reused, and recycled. This paper examines how the producers of electronic medical equipment objectives are as follows: 1) to gain a better understanding of (e-medical equipment) attempt to reduce the environmental impacts the initiatives undertaken by the of their products during its entire life cycle through different e-medical equipment producers to green their products, 2) to initiatives. The main objectives are as follows: to gain a better assess the relative importance of such initiatives, 3) to understanding of these environmentally proactive initiatives, to analyze the main drivers of these initiatives and 4) to examine assess their relative importance, to analyze the main drivers and to the key benefits derived from these initiatives. -

Mogollon, CML, Leiden University Dr. Jotte de Koning, Industrial Design, TU Delft 3 This page is intentionally left blank 4 Abstract Food waste is a global issue that causes various but significant global impacts, wasting millions of hectares of arable land, 0.75 to 1.25 trillion of cubic meter of water per year, and about 1.5% of the global energy production. In developed nations, food waste occurs mainly at the retail and consumer stage. By 2050, 80% of the global food consumption will take place within cities. Cities are also a key nexus of energy, water, and food flows. Amsterdam offers an interesting case study as the city does not have any comprehensive strategy to tackle the food waste produced within its boundaries. Yet, the city has shown ambitions in transforming itself into a sustainable metropolis with strong renewable energy and circular strategies. This study uses the Food-Energy-Water (FEW) Nexus approach, particularly suited to understand the interactions and interconnections between Amsterdam’s food flows and the energy and water systems.
